DTC P160A:00 [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM)]

• The SRS air bag system can be identified by whether or not the seat track position sensor is present.

― Standard deployment control system: Without seat track position sensor

― Two-step deployment control system: With seat track position sensor

System malfunction location	Configuration data unmatched with body control module (BCM)
Detection condition	• The configuration information for the steering wheel position between the SAS control module and the body control module (BCM) does not match.
Fail-safe	• Not applicable
Possible cause	• SAS control module configuration information for the steering wheel position setting not implemented • SAS control module configuration information for the steering wheel position setting invalid • Body control module (BCM) configuration information for the steering wheel position setting not implemented • Body control module (BCM) configuration information for the steering wheel position setting invalid • SAS control module malfunction

Step	Inspection	Results	Action
1	PERFORM BODY CONTROL MODULE (BCM) CONFIGURATION • Perform the body control module (BCM) configuration using the M-MDS. (See CONFIGURATION.) • Clear the DTC for the SAS control module using the M-MDS. (See CLEARING DTC.) • Perform the DTC inspection for the SAS control module using the M-MDS. (See DTC INSPECTION.) • Are the same Pending DTCs present?	Yes	Go to the next step.
No	DTC troubleshooting completed.
2	PERFORM SAS CONTROL MODULE CONFIGURATION • Perform the SAS control module configuration using the M-MDS. (See CONFIGURATION.) • Clear the DTC for the SAS control module using the M-MDS. (See CLEARING DTC.) • Perform the DTC inspection for the SAS control module using the M-MDS. (See DTC INSPECTION.) • Are the same Pending DTCs present?	Yes	Perform the repair completion verification.
No	DTC troubleshooting completed.
Repair completion verification	PERFORM SAS CONTROL MODULE DTC INSPECTION • Clear the DTC for the SAS control module using the M-MDS. (See CLEARING DTC.) • Perform the DTC inspection for the SAS control module using the M-MDS. (See DTC INSPECTION.) • 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. (See SAS CONTROL MODULE REMOVAL/INSTALLATION [STANDARD DEPLOYMENT CONTROL SYSTEM].) (See SAS CONTROL MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)
No	DTC troubleshooting completed.
