DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If “DTC CONFIRMATION PROCEDURE” has been previously conducted, always turn the ignition switch OFF
and wait at least 10 seconds before conducting the next test.

>> GO TO 2.

2.

CHECK DTC DETECTION

With CONSULT

1.

Turn the ignition switch OFF to ON.

CAUTION:

Be sure to wait of 10 seconds after turning ignition switch OFF or ON.

2.

Perform self-diagnosis for “CHASSIS CONTROL”.

Is DTC “C1BB5-00” detected?

YES

>> Proceed to 

DAS-233, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-44, "Intermittent Incident"

.

NO-2

>> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000010721731

1.

CHECK CONNECTOR

1.

Turn the ignition switch OFF.

2.

Disconnect the chassis control module harness connector.

3.

Check the connector for disconnection or looseness.

4.

Check the pin terminals for damage or loose connection with harness connector.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace error-detected parts, securely lock the harness connector, and GO TO 2.

2.

PERFORM SELF-DIAGNOSIS (1)

1.

connect the chassis control module harness connector.

2.

Perform self-diagnosis for “CHASSIS CONTROL”.
