Results

Action
1
INSPECT DTCs IN SAS CONTROL MODULE
•  Clear the DTC for the SAS control module using the M-MDS.

•  Does the air bag system warning light illuminate?
Yes
Perform the repair completion verification.
No
Replace the instrument cluster and perform the repair completion verification.
(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
Repair completion verification
PERFORM SAS CONTROL MODULE DTC INSPECTION
•  Clear the DTC for the SAS control module using the M-MDS.
•  Perform the DTC inspection for the SAS control module using the M-MDS.
•  Is the same Pending DTC present?
Yes
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.
(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].)
If the CAN communication is normal, perform the diagnosis from Step 1.
•  If the malfunction recurs, replace the SAS control module.
No
DTC troubleshooting completed.
