Diagnostic Procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | INSPECT CONTACTS OF SAS CONTROL MODULE CONNECTORS 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. (See AIR BAG SYSTEM SERVICE WARNINGS.) (See AIR BAG SYSTEM SERVICE CAUTIONS.) • Turn the ignition switch to the LOCK position. • Disconnect the negative battery cable and wait for 1 min or more. (See BATTERY REMOVAL/INSTALLATION [L8, LF].) • Are all SAS control module connectors securely connected? | Yes | Go to the next step.
No | Reconnect the SAS control module connectors properly.
2 | VERIFY POORLY CONNECTED DETECTOR BARS OF SAS CONTROL MODULE CONNECTORS • Remove the column cover. (See COLUMN COVER REMOVAL/INSTALLATION.) • Disconnect the clock spring connector. (See CLOCK SPRING REMOVAL/INSTALLATION.) • Remove the glove compartment. (See GLOVE COMPARTMENT REMOVAL/INSTALLATION.) • Disconnect the passenger-side air bag module connector. (See PASSENGER-SIDE AIR BAG MODULE REMOVAL/INSTALLATION.) • Disconnect the driver and passenger-side seat connectors. (See SEAT REMOVAL/INSTALLATION.) • Remove the back trim. (See BACK TRIM REMOVAL/INSTALLATION.) • Remove the driver and passenger-side pre-tensioner seat belt connectors. (See SEAT BELT REMOVAL/INSTALLATION.) • Remove the console panel. (See CONSOLE PANEL REMOVAL/INSTALLATION.) • Disconnect the SAS control module connectors. (See SAS CONTROL MODULE REMOVAL/INSTALLATION.) • Verify the condition of the poorly connected detector bars of the SAS control module connectors. (Corrosion, damage, and disconnected pins) • Are the poorly connected detector bars of the SAS control module connectors normal? | Yes | Go to the next step.
No | Replace the air bag wiring harness.Turn the ignition switch to the ON position.
3 | PERFORM SAS CONTROL MODULE DTC INSPECTION • Reconnect the disconnected connectors. • Connect the negative battery cable. • Turn the ignition switch to the ON position. • Clear the DTC for the SAS control module using the M-MDS. (See CLEARING DTC [AIR BAG SYSTEM].) • Perform the DTC inspection for the SAS control module using the M-MDS. (See DTC INSPECTION [AIR BAG SYSTEM].) • Are the same DTCs present? | Yes | Replace the SAS control module. (See SAS CONTROL MODULE REMOVAL/INSTALLATION.)
