NO - INSPECTION END




Diagnosis Procedure
1.CHECK FRONT RH SHOCK ABSORBER ACTUATOR CIRCUIT (1)
1. Disconnect the E-SUS control unit harness connector.
2. Check the resistance between the E-SUS control unit harness connector.





Is the inspection result normal?
YES - GO TO 3.
NO - GO TO 2.
2.CHECK FRONT RH SHOCK ABSORBER ACTUATOR CIRCUIT (2)
1. Disconnect the front RH shock absorber actuator harness connector.
2. Check the continuity between the E-SUS control unit harness connector and front RH shock absorber actuator harness connector.





Is the inspection result normal?
YES - GO TO 3.
NO - Repair or replace the malfunctioning harness or connector.
3.CHECK FRONT RH SHOCK ABSORBER ACTUATOR
Perform the front RH shock absorber actuator. Refer to C1D12.

2. Select "FR ACTUATOR CRNT" of "DATA MONITOR" for E-SUS control unit.
3. Drive the vehicle and check whether it is within the following range.

FR ACTUATOR CRNT : Approx. 0.65 - 2.0 A

Is the inspection result normal?
YES - Check pin terminal and connection of each harness connector for damage or loose connections.
Repair or replace error-detected parts.
NO - Replace E-SUS control unit. Refer to Exploded View.




Component Inspection
1.PERFORM ACTIVE TEST
With CONSULT-III
1. Connect the E-SUS control unit harness connector and front RH shock absorber actuator harness connector.
2. Select "FRONT RIGHT ACTUATOR" in "ACTIVE TEST".
3. On the display, change the "Operation half cycle", and check that the operation noise is heard from the actuator.





Is the inspection result normal?
YES - INSPECTION END
