Lada Kalina does not engage reverse gear: reasons, reverse gear, diagram

During operation, the owners of the domestic Lada Kalina model identified a transmission flaw; reverse gear does not engage. There are several reasons that cause a malfunction of this nature. A modern car is stuffed with electronic devices, one of which can also serve as the initiator of this breakdown.

In our article we will try to touch in detail on the problem when the reverse gear in the transmission unit does not engage. Let's consider the reasons that cause this malfunction, as well as methods that allow you to independently find and eliminate the unpleasant defect.

Is there no way to engage reverse? What are the reasons?

At the very beginning, you should not rush and frantically dismantle and disassemble such a complex unit as a gearbox if the reverse gear does not engage. You should take a closer look at the shift lever; perhaps the reason is hidden there. The link paired with the cardan in the switching mechanism are quite often the culprits of such a breakdown. There is no way to do without a viewing hole here.
Among the probable reasons when the reverse speed does not work may be a failed release bearing. However, such a development of events would inevitably lead to the inability to normally engage any gear, and the process itself would be determined by the presence of crunches and difficulties.
Also, when the reverse gear does not work, the reverse gear locking mechanism on the Lada Kalina may break down. To determine whether there is a malfunction, you will need to remove the shift lever handle and visually inspect this unit.
There are frequent cases of damage to the wiring that is connected to the solenoids of the reverse stage locking unit. Let's talk about this moment next.

How to fix the problem

All these problems will not allow you to drive safely. Therefore, it is urgent to repair worn elements.

Repair reverse gear chain

Most problems are related specifically to the wiring, which could have a break.

Starting at the fuse box, check the voltage at fuse 21. If everything is in order, then check the connector, which is located in the shift lever, under the leather cover. To do this, be sure to close the circuit by lifting the locking ring up.

If the problem remains unresolved, check the voltage at the solenoid and at its switching chips. To do this, you will have to unwind the twist of wires that goes from the fuse to the solenoid.

Adjust the rocker drive

Sometimes, to eliminate problems with gear shifting, you just need to adjust the rocker drive.

The problem associated with selecting reverse gear is solved by loosening the rocker clamp and placing the selector lever in the reverse gear position. After this, the clamp is tightened again.

The adjustment process can be entrusted to an authorized dealer. The masters will set the backstage in the correct position, this will take no more than 10 minutes.

Replace the plastic bushings of the gear shift mechanism

An extraneous rattling sound in the gearbox can irritate the owner. It's all due to the plastic bushings of the scenes.

To replace it, you need to remove the soft cover from the gear shift lever and unscrew the bolt that secures the lever with the rocker. Then you should dismantle the old worn bushings and install new ones in their place. It is advisable to use fluoroplastic bushings - they are more durable compared to factory ones.

Reverse gear "Lada Kalina"

After this procedure, extraneous sounds from the scenes will disappear, and reverse gear will engage more clearly.

Adjust or replace clutch cable

If the gears no longer engage clearly, you can try adjusting or replacing the clutch cable. For this:

Open the hood and remove the air filter housing, after first disconnecting the air flow sensor.
Remove the clutch cable from the fork.
Remove the driver's side front wheel. Now it is possible to remove the cable mounting bracket to the gearbox.
To remove the bracket from the cable, unscrew the plastic adjusting nut.
Remove the clutch pedal by removing the clamp securing it.
Pull the clutch cable through the interior. Install the new cable in reverse order.

To adjust the cable, you need to look at the gas, brake and clutch pedals. They must be on the same level. If the clutch pedal is not level with the other pedals, then tighten the adjusting nut located on the clutch fork. Bring the pedal to the same level.

Repair the box

The problem may be hidden inside the box. This is usually due to wear on the gears and stabilizers.

Dismantling and repairing the locking mechanism

About theory.

The solenoid power circuit in the Lada Kalina car includes a switch ring located in the gear selector handle. The device operates as follows. By lifting the ring, the driver activates the power supply to the solenoid, which in turn causes the reverse speed control unit to unlock. Access to activating this transfer is now open. When the lever is moved to the required position, the limit switch located on the Lada Kalina transmission housing is activated. This allows you to activate the rear brake lights and an audible warning signal sent through the interior speaker.

Malfunction of the electrical wiring connecting the gearbox

Since the solenoid is directly connected to the vehicle ground, you also need to check the operation of the fuses. Reverse gear may not engage due to damage to one switch. Here it is advisable to use a multimeter and perform a “test” of the conditionally burnt element. If there is nothing at hand, then you can simply close the contacts. But you should be extremely careful, because if we are talking about a short circuit in the wiring, this can even lead to a fire.

Every car owner is required to have spare fuses with him in case of emergency. It is better to close the contacts with it, having first removed it from another power circuit. After this, the engine starts, reverse gear is engaged and an attempt is made to move. If the car moves forward, then the problem lies deeper.

Repair process

If reverse gear is lost, the following procedure must be performed. By participating in the circuit of the fuse link “F21”, +12V power is sent to the winding of the solenoid “L1”. There is a switch “S1” in the handle, which closes the ground contact, which causes the solenoid coil to activate.
The fuse we are interested in is located inside the mounting block and is installed in the eighth socket of the LADA Kalina, if you count from the left. The current strength for this insert is 10A. If suddenly the fuse turns out to be faulty, then replace it with a similar insert with the specified characteristics.
Next, we check the switch itself. For this purpose, lift the handle cover and find the connector. It is connected directly to the switch. We carefully disconnect.
We take a regular paper clip and use it to close the corresponding contacts in the connector.
We make an attempt to engage reverse gear on the LADA Kalina, and when this action was successful, we conclude that the switch is unsuitable. If we fail, then we continue to diligently search for the source of the trouble.
Remove the solenoid connector and insert two pins into its contact grooves. Now we call for help with a tester, which we use to measure the voltage. The display of the device should display the number 12 (naturally, Volts). We load this local circuit by connecting a light bulb. A 5-watt device will be sufficient. If the lamp refuses to light, then we are dealing with a break. The presence of voltage here can be explained by the presence of resistance resulting from the natural formation of copper oxide.
In 99 percent of cases of wiring malfunction, expressed in fractures or breaks in the supply wires, the cause is the harness, which is located next to the clamp on the pallet.
We dismantle this clamp by carefully squeezing its fastening elements.
Disconnect the rear brake light switch connector. We take out the tourniquet. Remove the insulating tape from the corrugated shell and remove the wires. If there is a break, it can be easily detected.
Using wire cutters, we pinch off the remains of the damaged wiring and install new wires, which we select with a similar cross-section. We recommend soldering the connecting node itself. Now let's isolate. Alternatively, you can use a new corrugation. Our goal is to prevent moisture penetration during operation.
We fix the harness with a new plastic clamp.
We connect the previously removed connectors and turn on the power to the solenoid.
The presence of a malfunction within the solenoid itself is a rather rare case, but possible. To check, we use the same tester. We measure the resistance at the terminals. Its value should be 2.2 ohms. If it turns out that the solenoid is the culprit, replacing it will require draining the transmission oil. Some dodgers manage to do without draining. After dismantling, they, with a deft movement of their hands, plug the hole with a suitable gag, and before installation, they sharply remove it. A slight loss of oil will still occur, but these crumbs can be topped up without any problems.
When installing the solenoid on the Lada Kalina, do not forget to lubricate the threaded part with sealing glue, otherwise after a while the oil will begin to treacherously ooze out of the box.

Fuse F21 is a 10A fuse in the fuse block, 8th from the left. Take it out and check it with a tester. If it is defective, replace it with a new one.
Check the switch by lifting the cover on the handle. This will free up access to the connector connected to the switch. Disable it carefully.

Reverse gear does not engage on Lada Kalina reasons

Using a paper clip, we close the contacts of the connector from which the wires are lowered under the floor of the car. Try to engage reverse gear. If this works, the switch is broken.

Lada Kalina reverse gear does not engage

Disconnect the connector from the solenoid and install 2 pins into it. Use a tester to change the voltage. The device readings should be 12 Volts. It is worth charging it with a light bulb (5 Watt or 12 Watt). If it does not light up, then there is an open circuit, and the voltage arises due to resistance formed due to copper oxide. Very often, breaks and fractures occur on the harness in the place where the clamp is located on the pallet.

Why does the reverse gear of the Lada Kalina not work?

Remove the clamp by pressing its fastenings at the bottom.
Disconnect the connector from the stop switch and remove the harness. Remove the electrical tape from the corrugation, after which you can remove the wires. In the event of a break or breakage, characteristic signs will be noticeable.
Use wire cutters to disconnect the wires and connect them of similar cross-section and diameter. The twist should be soldered and insulated (you can use heat shrink). If necessary, put on a new corrugation. This is done so that moisture does not penetrate inside, otherwise it is possible that all the troubles will happen again. The harness should be secured with a plastic clamp.

Connect the connectors and check the operation of the solenoid. Failure of this element is quite rare. To check it you need to connect a tester. The resistance should be 2.2 Ohm. If the cause of the malfunction lies there, you will need to drain the oil from the box. One option is to quickly block the hole with something and install a new solenoid. In this case, it is important to apply sealant to the threads so that oil does not ooze down the threads during operation.

Other reasons

If all of the above manipulations did not lead to the expected result, and the reverse gear disappeared, then it remains to perform a few more testing techniques, namely:

It is possible that a malfunction has occurred in the fastening mechanism of the gear selection unit. We check and fix it.
The fixing bolt has received irreparable damage and does not perform its function. We change.
The spring in the gearbox broke and the reverse gear disappeared.

As you can see, the reasons may be different, but the danger and trouble in these three situations is that it will inevitably be necessary to dismantle the transmission unit itself.

Why the Lada Kalina stopped turning on: reasons and solutions

Failure of the locking mechanism fuse

Since this device in the Lada Kalina is of electronic origin, it is first of all worth examining the electronic systems. To do this, you need to check the condition of the corresponding relay and fuse, which are located in the mounting block. Its cover is located under the handle for turning on the dimensions. Open it and evaluate the functionality of the fuse responsible for the operation of the transmission reverse lock circuit.

The documentary designation of the required element is F21. The current rating of this component is 10A. The location can be seen in the photo below.

F21 (10) - the fuse you need

To determine the true cause, remove the fuse from its socket and carefully analyze the condition of the jumpers. If the part is damaged, the integrity of the jumper will be compromised.

Option to solve the problem: replacing the fuse with a new one is the only way.

Important! If a newly installed mechanism quickly fails, then the cause must be sought in the solenoid.

Magnetic switch failure

As a rule, such breakdowns are not so common due to the fact that the magnet itself is a fairly durable spare part and has a sufficient working life. However, if the reverse gear fails, it would not be superfluous to check it too.

Lada Kalina reverse gear failures and how to fix them

There are quite a few reasons for the failure of the rear gear of the Lada Kalina. And it is not always easy to find out the origin of this breakdown. Reverse speed in cars that are equipped with a large number of electronics and sensors is generally not activated when problems arise specifically with the electronics.

Reverse gear does not engage: reasons

Let's start setting up the car with the simplest thing. Before a global search for a breakdown, it is necessary to check the serviceability of the gear lever; it is probably the one that has failed. The cardan and rocker often break. Maybe the splines just “licked off”, or maybe the tension of the clamp has decreased. All these problems can only be removed from the inspection pit.
If engaging the gears is difficult and they “crunch,” then the problem lies in the release bearing, but this is unlikely.
Failure of the reverse gear can occur when the reverse locking mechanism fails. To confirm your assumption, you need to dismantle the gear shift lever together with the dashboard and inspect everything thoroughly.

Often the problem with reverse gear failure is the failure of the transmission lock solenoid wiring. It may break or break. You can fix this problem yourself.

Repair of the rear gear locking mechanism Lada Kalina

Current is supplied to the solenoid through the switch ring. It is located on the gear lever. When reverse gear is engaged, the ring rises and the solenoid is turned on, the rod is pulled into the solenoid and reverse gear operates. Then the limit switch located on the gearbox turns on, and the rear brake lights light up, accompanied by an intermittent beeping sound inside the car.

Materials and equipment for repairs

To fix a faulty Lada Kalina gear shift, you will need:

Heat shrink or electrical tape.
Car key for 36.
A piece of copper wire.
Tester for checking the presence of voltage.
Soldering device.

The work on repairing the rear gear of the Lada Kalina takes place in several stages:

Solenoid control: diagram

On the Lada Kalina gearbox, the solenoid control circuit consists of the L1 solenoid itself, 10 A fuse F21, and switch S1. A current of 12 V is supplied to the solenoid through a fuse. Then the circuit is closed to ground at the gear lever and the solenoid coil begins to operate thanks to the switch. Fuse F21 is located in a special fuse block, it is the eighth on the left side. It must be removed and checked for functionality using a tester. If the fuse is faulty, you need to replace it with a new one.

If everything is in order with the fuse, you need to make sure that the switch is operational. It is located under the pen cover. It is necessary to pull out the connector from the switch and use a paper clip to close the contacts in the connector. You can try to put the car in reverse. If everything works, then the cause was a faulty switch. But the reverse gear may not engage, then you will have to look further for the reason.

Remove the connector from the solenoid and place two small pins in it. We measure the voltage using a tester. It should be 12 V. Also, to check, turn on a 5 W light bulb at 12 V. The absence of light indicates a break, and the voltage comes from the resistance formed by the oxide film.

Mostly, the harness fails at the point where the clamp is installed on the pallet. To eliminate this type of damage, you need to remove the clamp, disconnect the connector from the stop switch and remove the entire harness. You will see that the entire corrugation is wrapped with electrical tape. It must be removed and the wires pulled out. If the wires are broken, you will see it immediately.

The defective wires must be cut off with wire cutters and new ones of the same diameter must be connected and the cross-sectional size must also be the same. To ensure a reliable connection, the twisting area must be soldered. If the corrugation also does not inspire confidence in you, then it also needs to be replaced, otherwise the problem will soon arise again due to moisture ingress. The harness must be secured with a plastic clamp.

Reverse gear on Lada “Kalina”: causes of malfunction and repair options

Some car owners are faced with an unpleasant situation - the reverse gear on the viburnum does not engage. In most cases, this happens at the most inopportune moment. Vehicle owners are concerned about why this happens and how to get rid of the problem. Below we will consider in detail all the possible causes of the malfunction, options for determining the location of the breakdown, and ways to fix it on your own.

Main reasons

If the reverse speed on a Lada “Kalina” vehicle has disappeared, we recommend immediately checking the quality of the transmission oil. Sometimes this substance loses its properties and changes consistency. With these changes, jamming is felt during gear shifting.

The main reasons that provoke a situation when reverse gear does not engage on the Lada Kalina include:

problems with the gear shift lever. Most situations are characterized by malfunctions in the rocker and driveshaft. Sometimes a breakdown can be caused by a weakening clamp or a violation of the integrity of the splines. To make an accurate determination, you will need to place the vehicle over the viewing hole;
malfunctions in the reverse gear locking mechanism. You can determine for sure whether the reverse speed on the Lada “Kalina” has disappeared because of this by removing the lever - the gear selector and the casing between the front seats. The driver can visually inspect the mechanism;
The release bearing needs adjustment. This is the least likely cause of a breakdown, since with this parameter switching is carried out with great effort and is accompanied by an unpleasant crunching sound.

Most often, the reverse gear on the viburnum does not engage due to breaks and refractions of the wires in the gear blocking system.

Algorithm for determining and debugging the blocking system

Before you start solving the question of why the reverse gear on the Lada “Kalina” does not engage, you should learn a little about the theory of the functioning of the locking system.

Power to the solenoid wiring is supplied through a special switch ring located on the gearshift handle. The principle of operation is as follows: the driver lifts the switch, which activates the solenoids, then the rod is pulled inward. Such actions lead to the fact that the reverse gear is unlocked.

After carrying out such manipulations, the car owner is able to switch the reverse gear; to do this, it is necessary to move the shift knob. Then the “limit switch”, which is located on the box, is activated, and the reverse signals light up, emitting a characteristic sound in the cabin.

To fix the problem you will need the following tools:

copper wire and soldering iron;
tester;
insulating tape (heat shrink);
wrench marked “36”.

Connection diagram for Kalina

The control circuit for the locking mechanism looks like this - a current of 12 volts passes through a special fuse. It is supplied to the solenoids, after which the circuit is closed using a switch on the lever. Then the solenoid coil starts up.

The debugging procedure occurs according to the following steps:

the required fuse is located on the safety block on the left side, it is the eighth in the list. You need to get it out and diagnose it using a special tester. If the unit malfunctions, it will need to be replaced;
We check the switch itself directly. To do this, you will need to lift the cover on the gearbox. Below it is a connector connected to the switch. Unplug slowly and carefully;
short the contacts using a paper clip. After this, you should try to switch to reverse gear. If the actions lead to the desired result, then the obstacle is a malfunction of the switch. If the rear one does not work, continue to determine the reasons;
Remove the plug from the solenoid and place 2 pins inside. Next, using diagnostic equipment, measure the voltage. The device should provide information that the voltage level is 12 volts. When connected to a 5-watt light bulb, a light signal should appear. If there are no changes, it means that there are breaks in the wires somewhere. In such a situation, the voltage is due to the resistance generated by the copper oxide. Most often, breaks and refractions are located in the section of the harness where the torpedo is located;

Voltage level measurement

remove the clamp. To do this, you need to squeeze the latch at the bottom;
Next you will need to disconnect the plug from the switch. After performing these manipulations, it is possible to pull out the tourniquet completely. Remove the insulating tape from the corrugation and analyze the wiring. If there are breaks or refractions, you will note visual signs;
damaged wires are removed using wire cutters, and in their place place new ones with the same cross-section and diameter. We recommend soldering the twisted area and applying insulation using heat shrink. If you wish, replace the corrugation with another one. Make sure that moisture does not get on the wiring;
After connecting all connectors, you can check the functioning of the system.

A broken solenoid is not a common problem. To determine this malfunction, you must connect a tester. When the device operates correctly, it will show 2.2 Ohm data. If the parameters do not match, you will need to drain the car oil from the gearbox.

There is an alternative option without removing the oil, but it requires certain skills and abilities. In such a situation, it is necessary to quickly close the hole through which the substance is escaping and place a new part. After installing the new solenoid, we recommend applying a sealant compound to the threaded area. If you skip this step, the substance will soon begin to flow through the threads.

Possible problems

Sometimes it happens that the diagnostics described above were carried out, but the result did not change - the Lada Kalina does not engage reverse gear. Then there are the following possible explanations:

The spring in the gearbox is damaged.
The mounting screw has been cut off.
There is a problem with the gear selection system locking mechanism.

The negative consequences in such situations are that eliminating them will require mandatory removal of the box. This type of debugging requires special knowledge and skills that are not always within the power of a car enthusiast.
