Diagnostic Procedure

Step	INSPECTION		Action
1	INSPECT DRIVER-SIDE SIDE AIR BAG MODULE CONNECTOR 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 .) Switch the ignition to off. Disconnect the negative battery cable and wait for 1 min or more . Disconnect the driver-side side air bag module connector installed to the lower side of the seat cushion of the front seat. Inspect the driver-side side air bag module connector. (Corrosion, damage, and disconnected pins) Is there any malfunction of the driver-side side air bag module connector?	Yes	Replace the driver-side side air bag module wiring harness.
1		No	Go to the next step.
2	INSPECT WIRING HARNESS BETWEEN SAS CONTROL MODULE AND DRIVER-SIDE SIDE AIR BAG MODULE Remove the column cover. (See COLUMN COVER REMOVAL/INSTALLATION .) Disconnect the clock spring connector. (See CLOCK SPRING REMOVAL/INSTALLATION .) Remove the passenger-side lower panel. (See LOWER PANEL REMOVAL/INSTALLATION .) Disconnect the passenger-side air bag module connector. (See PASSENGER-SIDE AIR BAG MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM] .) Disconnect the driver and passenger-side front seat connector. (See FRONT SEAT REMOVAL/INSTALLATION .) Remove the C-pillar trim. (See C-PILLAR TRIM REMOVAL/INSTALLATION .) Disconnect the driver and passenger-side curtain air bag module connector. (See CURTAIN AIR BAG MODULE REMOVAL/INSTALLATION .) Remove the B-pillar lower trim. (See B-PILLAR LOWER TRIM REMOVAL/INSTALLATION .) Disconnect the driver and passenger-side pre-tensioner seat belt connector. (See FRONT SEAT BELT REMOVAL/INSTALLATION .) Remove the front console. (See FRONT CONSOLE REMOVAL/INSTALLATION .) Disconnect the all SAS control module connectors. (See SAS CONTROL MODULE REMOVAL/INSTALLATION .) Inspect the wiring harnesses between SAS control module connector terminal 2F and driver-side side air bag module connector terminal A, and SAS control module connector terminal 2B and driver-side side air bag module connector terminal B for the following: Short circuit between terminals Short to body ground Open circuit NOTE: Inspect for continuity while shaking the wiring harness between the SAS control module and driver-side side air bag module. Is the wiring harness normal?	Yes	Go to the next step.
2		No	Replace the wiring harness between the SAS control module and the driver-side side air bag module.
3	INSPECT THE WIRING HARNESS BETWEEN THE SAS CONTROL MODULE AND DRIVER-SIDE SIDE AIR BAG MODULE FOR A SHORT CIRCUIT TO THE POWER SUPPLY Connect the negative battery cable. Switch the ignition to ON with SAS control module connector and driver-side side air bag module connector disconnected. Measure the voltage of SAS control module connector terminals 2F and 2B of SAS control module harness side connector. NOTE: Measure the voltage while shaking the wiring harness between the SAS control module and driver-side side air bag module. Is the voltage measured?	Yes	Replace the wiring harness between the SAS control module and the driver-side side air bag module.
3		No	Go to the next step.
4	INSPECT DRIVER-SIDE SIDE AIR BAG MODULE Switch the ignition to off. Disconnect the negative battery cable and wait for 1min or more . Connect the SST (Fuel and thermometer checker) or apply 2 ohms resistance to the driver-side side air bag module connector terminals A-B. Set the SST (Fuel and thermometer checker) to 2 ohms . Except for the driver-side side air bag module connector, reconnect all disconnected connectors. Connect the negative battery cable. Switch the ignition to ON. Clear the DTC for the SAS control module using the M-MDS. (See CLEARING DTC [TWO-STEP DEPLOYMENT CONTROL SYSTEM] .) Perform the DTC inspection for the SAS control module using the M-MDS. (See DTC INSPECTION [TWO-STEP DEPLOYMENT CONTROL SYSTEM] .) Are the same DTCs present?	Yes	Go to the next step.
4		No	Replace the driver-side side air bag module. (See SIDE AIR BAG MODULE REMOVAL/INSTALLATION .)
5	PERFORM SAS CONTROL MODULE DTC INSPECTION Switch the ignition to off. Disconnect the negative battery cable and wait for 1min or more . Disconnect the SST (Fuel and thermometer checker) or the 2 ohms resistance. Connect the driver-side side air bag module connector. Connect the negative battery cable. Switch the ignition to ON. Clear the DTC for the SAS control module using the M-MDS. (See CLEARING DTC [TWO-STEP DEPLOYMENT CONTROL SYSTEM] .) Perform the DTC inspection for the SAS control module using the M-MDS. (See DTC INSPECTION [TWO-STEP DEPLOYMENT CONTROL SYSTEM] .) Are the same DTCs present?	Yes	Replace the SAS control module. (See SAS CONTROL MODULE REMOVAL/INSTALLATION .)
5		No	DTC troubleshooting completed.
