Results

Action
1
INSPECT SAS CONTROL MODULE CONNECTORS CONNECTION CONDITION
Warning
•  Handling the component parts improperly can accidentally operate (deploy) the air bag module, which may seriously injure you. Read the service warnings/cautions and the workshop manual before handling the air bag system components.
•  Switch the ignition off.
•  Disconnect the negative battery terminal and wait for 1 min or more.
•  Disconnect the driver-side knee air bag module connector.
•  Disconnect the driver-side air bag module connectors.
•  Remove the clock spring.
•  Disconnect the passenger-side air bag module connector.
•  Disconnect the driver and passenger-side side air bag module connectors.
•  Disconnect the driver and passenger-side front seat connectors.
•  Disconnect the driver and passenger-side curtain air bag module connectors.
•  Disconnect the driver and passenger-side front pre-tensioner seat belt connectors.
•  Disconnect the driver and passenger-side rear pre-tensioner seat belt connectors.
•  Are all SAS control module connectors securely connected?
Yes
Go to the next step.
No
Reconnect the SAS control module connectors properly and perform the repair completion verification.
2
VERIFY POOR CONNECTION DETECTOR BAR OF SAS CONTROL MODULE CONNECTOR
•  Disconnect the all SAS control module connectors.
•  Verify the condition of the detector bars of the SAS control module connectors (both sides of connector). (Corrosion, damage, and disconnected pins)
•  Are the detector bars of the SAS control module connectors normal?
Yes
Perform the repair completion verification.
No
Replace the malfunctioning part according to inspection results.
Perform the repair completion verification.
Repair completion verification
PERFORM DTC INSPECTION FOR SAS CONTROL MODULE
•  Connect the SAS control module connectors.
•  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.
