Automatic transmission
When starting off or accelerating in forward gears (4WD mode)
1. Raise the vehicle on all four wheels.
2. Place a mark (A) on either propeller shaft #1 or propeller shaft #2 (B).
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. Apply the parking brake securely and measure the time it takes to turn the propeller shaft 10 times.
- If the measured time is more than 10 seconds, the 4WD system is normal.
- If the measured time is less than 10 seconds, there is a malfunction in the 4WD system. Check the differential fluid. If everything is OK with it, replace the differential-torque distributor housing assembly.
When starting off or accelerating in reverse gear (4WD mode)
1. Raise the vehicle on all four wheels.
2. Place a mark (A) on either propeller shaft #1 or propeller shaft #2 (B).
3. Start the engine and warm it up to normal operating temperature (the radiator fan will turn on at least twice).
4. With the engine running at idle speed, shift to the [R] position.
5. Apply the parking brake securely and measure the time it takes to turn the propeller shaft 10 times.
- If the measured time is more than 10 seconds, the 4WD system is normal.
- If the measured time is less than 10 seconds, there is a malfunction in the 4WD system. Check the differential fluid. If everything is OK with it, replace the differential-torque distributor housing assembly.
Manual transmission
When starting off or accelerating in forward gears (4WD mode)
1. Raise the vehicle on all four wheels.
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. Apply the parking brake securely.
- If the engine stalls, the 4WD system is OK.
- If the engine continues to run, there is a fault in the 4WD system. Check the differential fluid. If everything is OK with it, replace the differential-torque distributor housing assembly.

Automatic transmission (AT)/ Manual transmission (MT)
When decelerating in forward gear (2WD)
1. Place chocks (A) under the front wheels, lift the left rear wheel and secure it to the safety stand (B) as shown in the figure.
2. Grasp the wheel and continuously turn it counterclockwise more than one revolution.
- If the wheel rotation force does not increase when decelerating in forward gear, the 2WD system operates normally.
- If the effort required to turn the wheel gradually increases, there is a fault in the system. Check the differential fluid. If everything is OK with it, replace the differential-torque distributor housing assembly.

- If the wheel rotation force does not increase, the 4WD system operates normally when decelerating in reverse gear.
- If the effort required to turn the wheel gradually increases, there is a fault in the system. Check the differential fluid. If everything is OK with it, replace the differential housing and torque distributor assembly.
