At the beginning of the movement or during acceleration in forward gears (4WD mode)
1. Raise the vehicle with all four wheels off the ground.
2. Mark the cardan shaft.
The label can be applied to any cardan shaft (#1 or #2).
3. Start the engine and warm it up until the radiator fan operates twice.
4. At the speed of x.x. set the automatic transmission selector lever to position 2, press the low hold switch to engage 1st gear.
5. Firmly tighten the parking brake and measure the time required to turn the driveshaft 10 times.
- If the measured time exceeds 10 seconds, the 4WD system operates normally at the start of a movement or during acceleration in forward gears.
- If the measured time is less than 10 seconds, the system is faulty. Check differential fluid. If everything is in order, replace the differential-torque distributor housing assembly.
At the beginning of the movement or during acceleration in reverse gear (4WD mode)
1. Raise the vehicle with all four wheels off the ground.
2. Mark the cardan shaft.
The label can be applied to any cardan shaft (#1 or #2).
3. Start the engine and warm it up to normal operating temperature (the radiator fan will turn on at least twice).
4. At the speed of x.x. set the automatic transmission selector lever to position R.
5. Firmly tighten the parking brake and measure the time required to turn the driveshaft 10 times.
- If the measured time is more than 10 seconds, the 4WD system operates normally at the beginning of the movement or during acceleration in reverse gear.
- If the measured time is less than 10 seconds, the system is faulty. Check differential fluid. If everything is in order with it, replace the housing of the differential-distributor, torque assembly.
During deceleration in forward gears (2WD mode)
1. Place wheel chocks under the front wheels, jack up one rear wheel and jack it up.
2. Grab the lifted wheel and continuously turn it in the direction corresponding to the vehicle moving forward, more than one revolution.
If the force to rotate is not increased, the 2WD system operates normally during deceleration in forward gears.
If the force to rotate gradually increases, the system is faulty. Check differential fluid. If everything is in order, replace the torque distributor differential housing assembly.
During deceleration in reverse gear (4WD mode)
1. Place wheel chocks under the front wheels, jack up one rear wheel and jack it up.
2. Grasp the raised wheel and turn it continuously in the direction of the vehicle's backward movement for more than one revolution.
- If the force to rotate gradually increases, the 4WD system operates normally during deceleration in reverse gear.
- If the force to rotate does not increase, the system is faulty.
Check differential fluid. If everything is in order, replace the differential-torque distributor housing assembly.
