Fluid - Differential: Testing and Inspection

RESERVE TANK FLUID (FOR ACTIVE CENTER DIFFERENTIAL AND ACTIVE YAW CONTROL SYSTEM) (CHECK FLUID LEVEL)

FLUID LEVEL CHECK

[WHEN THE SCAN TOOL IS NOT USED]

1. Remove the trunk room side trim lid on the right of the trunk room.

2. If the vehicle has been run, leave it for 90 min. or more in an ordinary temperature {10 - 30°C (50 - 86°F)} to allow the accumulator internal pressure to drop.
NOTE:
If the ambient temperature is 10°C (50°F) or less, allow more time to leave the vehicle to stand idle.





3. Check that the oil reservoir fluid level is in between MAX and MIN.
4. If the fluid level is not in between MAX and MIN, fill the specified fluid.
Specified fluid: DIAMOND ATF-SP III
5. Install the trunk room side trim lid.

[WHEN THE SCAN TOOL IS USED]

1. Remove the trunk room side trim lid on the right of the trunk room.

2.
CAUTION:
Turn the ignition switch to the "LOCK (OFF)" position before connecting or disconnecting the scan tool.

Set the scan tool to the 16-pin data link connector. (Refer to Reading and Clearing Diagnostic Trouble Codes.)

3. Turn the ignition switch to the ON position.

4. Using the scan tool, forcibly activate the hydraulic unit (item No. 03) to reduce the pressure inside the accumulator.
NOTE:

- With the forced activation (oil level check mode), the hydraulic unit direction valve is operated 20 times to right and left, and then the operation is canceled automatically. Also, using the clear key on the scan tool, the activation can be forcibly canceled.
- When the functions are suspended by the fail-safe function, the hydraulic unit cannot be forcibly activated.





5. Check that the oil reservoir fluid level is in between MAX and MIN.
6. If the fluid level is not in between MAX and MIN, fill the specified fluid.
Specified fluid: DIAMOND ATF-SP III
7. Install the trunk room side trim lid.
