Active Center Differential (ACD) Operation Check

ACD OPERATION CHECK

1.
CAUTION:
Before connecting or disconnecting scan tool, always turn the ignition switch to the LOCK (OFF) position.

Connect scan tool to the data link connector. (Refer to Reading and Clearing Diagnostic Trouble Codes.)

2. Start the engine.

3. Position the steering wheel in a straight ahead direction.

4. Drive the vehicle at 20 km/h (12.4 mph) or less, carry out the scan tool actuator test (item No.05), and forcibly activate the ACD. Then, turn the steering wheel 180° or more to the right or left, and check that tight corner braking occurs.
NOTE:

- The forced activation (item No.05: ACD operation check mode) is continued for 1 minute, then it will be cancelled automatically. Also, using the clear key on the scan tool, the activation can be forcibly cancelled.

- When the ACD functions are stopped due to the fail-safe, the forced activation cannot be performed.

- The occurrence levels of body vibration and noise caused by the tight corner braking phenomenon will differ depending on the conditions of tire and road surface.

- If the tight corner braking phenomenon does not occur, the system may have an abnormality. Therefore, check the hydraulic pressure.
