Repair completion verification
PERFORM SAS CONTROL MODULE DTC INSPECTION
•  Reconnect all disconnected connectors.
•  Connect the negative battery terminal.
•  Switch the ignition ON (engine off or on).
•  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.
•  Are the same Pending DTCs 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.
