DTC Detection Logic:

DTC CONFIRMATION PROCEDURE
1.DTC REPRODUCTION PROCEDURE
With CONSULT-III
1. Perform "SELF DIAGNOSTIC MODE" item on "ACTIVE TEST" of RAS control unit.

CAUTION:
Perform the active test while vehicle is stopped.
2. Perform RAS control unit self-diagnosis.
Without CONSULT-III
1. Start the engine.
2. Perform the self-diagnosis. Refer to Diagnosis Description.
Is DTC "C1902", "C1903", "C1904", "C1910", "C1913" or "RAS warning lamp flickering pattern:13" detected?
YES - Proceed to diagnosis procedure. Refer to C1902.
NO - INSPECTION END




Diagnosis Procedure
1.CHECK RAS MOTOR CIRCUIT
1. Turn the ignition switch OFF.
2. Disconnect RAS control unit harness connector.
3. Disconnect RAS motor harness connector.
4. Check the continuity between RAS control unit harness connector and RAS motor harness connector.





5. Check the continuity between RAS control unit harness connector and ground.





Is the inspection result normal?
YES - GO TO 2.
NO - Repair or replace the harnesses and connectors.
2.CHECK RAS MOTOR
Check RAS motor. Refer to C1902.
Is the inspection result normal?
YES - GO TO 3.
NO - Replace RAS actuator assembly. Refer to Exploded View.
3.PERFORM ACTIVE TEST
With CONSULT-III
1. Connect RAS control unit harness connector.
2. Connect RAS motor harness connector.
3. Perform "SELF DIAGNOSTIC MODE" item on "ACTIVE TEST" of RAS control unit.

CAUTION:
Perform the active test while vehicle is stopped.
4. Check "MOTOR VOLTAGE", "MOTOR CURRENT" and "MTR CRNT OPE" while performing the active test.





Without CONSULT-III
1. Disconnect RAS control unit harness connector.
2. Disconnect RAS motor harness connector.
3. Start the engine.
4. Check the voltage between RAS control unit harness connector and ground.





Is the standard value?
YES - GO TO 4.
NO - Replace RAS actuator assembly. Refer to Exploded View.
4.PERFORM SELF-DIAGNOSIS
With CONSULT-III
1. Turn the ignition switch ON.
2. Perform RAS control unit self-diagnosis.
Without CONSULT-III
1. Connect RAS control unit harness connector.
2. Connect RAS motor harness connector.
3. Start the engine.
4. Perform the self-diagnosis. Refer to Diagnosis Description.
Is DTC "C1902", "C1903", "C1904", "C1910" or "RAS warning lamp flickering pattern:13" detected?
YES - Replace RAS control unit. Refer to Exploded View.
NO - GO TO 5.
5.CHECK INFORMATION
With CONSULT-III
Check the "DATA MONITOR" value of each DTC detected with the self-diagnosis function. Refer to RAS Control Unit.
Is each data the standard value?
YES - Check each harness connector pin terminal for disconnection.
NO - Replace RAS control unit. Refer to Exploded View.




Component Inspection
1.CHECK RAS MOTOR
Check the continuity between RAS motor connector terminals.





Is the inspection result normal?
YES - INSPECTION END
NO - Replace RAS actuator assembly. Refer to Exploded View.




Special Repair Requirement

BEFORE REPLACING RAS CONTROL UNIT
- Record the self-diagnosis results (history).

CAUTION:
- Never erase the memory (history) of self-diagnosis results when replacing RAS control unit after diagnosis.
- Erase the memory of the self-diagnosis results (record) after printing out or recording all the values of "DATA MONITOR".
