When pulling away and accelerating in forward gears (4WD mode)
Manual Transmission (ITUC):
1. Raise the car with all four wheels (see ch. 1).
2. Start the engine and warm it up to normal operating temperature (the radiator fan will turn on at least twice).
3. While the engine is running at idle speed, shift into 1st gear and disengage the clutch.
4. Securely apply the parking brake.
- If the engine stalls, the 4WD system is OK.
- If the engine continues to run, there is a problem with the 4WD system. Check differential fluid. If everything is in order, replace the differential-torque distributor housing assembly.
Automatic transmission (AKP):
1. Raise the car with all four wheels (see ch. 1).
2. Mark either the front or rear driveshaft.
3. Start the engine and warm it up to normal operating temperature (the radiator fan will turn on at least twice).
4. While the engine is running at idle speed, shift to position 1.
5. Securely apply the parking brake and measure the time required to turn the driveshaft 10 times.
- If the measured time is greater than 10 seconds, the 4WD system is OK.
- If the measured time is less than 10 seconds, there is a malfunction in the 4WD system. Check differential fluid. If everything is in order, replace the differential-torque distributor housing assembly.

3. Start the engine and warm it up to normal operating temperature (the radiator fan will turn on at least twice).
4. While the engine is running at idle speed, shift to R.
5. Securely apply the parking brake and measure the time required to turn the driveshaft 10 times.
- If the measured time is greater than 10 seconds, the 4WD system is OK.
- If the measured time is less than 10 seconds, there is a malfunction in the 4WD system. Check differential fluid. If everything is in order, replace the differential-torque distributor housing assembly.
When decelerating in forward gear (2WD mode)
1. Place chocks under the front wheels, lift the left rear wheel and secure it to the safety bars as shown.
2. Grasp the wheel and continuously turn it counterclockwise for more than one turn.
- If the force to rotate the wheel does not increase, the 2WD system will operate normally when decelerating in forward gear.
- If the force to rotate the wheel gradually increases, there is a malfunction in the system. Check differential fluid. If everything is in order, replace the differential-torque distributor housing assembly.
