Diagnostic Procedure

STEP	INSPECTION		ACTION
1	INSPECT DSC HU/CM CONNECTOR Switch the ignition to off. Disconnect the negative battery cable and wait for 1 min or more . Disconnect the DSC HU/CM connector. Inspect the DSC HU/CM connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion). Is there any malfunction?	Yes	Repair or replace the terminal, then go to next step.
1		No	Go to the next step.
2	INSPECT SAS CONTROL MODULE CONNECTOR Remove the front console. (See FRONT CONSOLE REMOVAL/INSTALLATION .) Disconnect the all SAS control module connectors. (See SAS CONTROL MODULE REMOVAL/INSTALLATION .) Inspect the SAS control module connector terminal for poor connection (such as damaged/pulled-out pins, and corrosion). Is there any malfunction?	Yes	Repair or replace the terminal, then go to next step.
2		No	Go to the next step.
3	INSPECT WIRING HARNESS BETWEEN DRIVER-SIDE SIDE AIR BAG MODULE AND SAS CONTROL 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 .) Inspect the wiring harness between SAS control module terminal 2H and DSC HU/CM terminal AO, SAS control module terminal 2D and DSC HU/CM terminal AL for the following: Short to body ground Open circuit Short circuit between terminals NOTE: Inspect for continuity while shaking the wiring harness between the DSC HU/CM and SAS control module. Is the wiring harness normal?	Yes	Go to the next step.
3		No	Replace the wiring harness between the SAS control module and the DSC HU/CM, then go to next step.
4	INSPECT THE WIRING HARNESS BETWEEN THE SAS CONTROL MODULE AND DSC HU/CM FOR A SHORT CIRCUIT TO THE POWER SUPPLY Connect the negative battery cable. Switch the ignition to ON with SAS control module and DSC HU/CM connector disconnected. Measure the voltage of SAS control module connector terminals 2H and 2D of SAS control module harness side connector. NOTE: Measure the voltage while shaking the wiring harness between the SAS control module and DSC HU/CM. Is the voltage measured?	Yes	Repair or replace the wiring harness for a possible short to power supply, then go to the next step.
4		No	Replace the DSC HU/CM, then go to the next step. (See DSC HU/CM REMOVAL/INSTALLATION .)
5	PERFORM SAS CONTROL MODULE DTC INSPECTION Switch the ignition to off. Disconnect the negative battery cable and wait for 1 min or more . Disconnect the SST (Fuel and thermometer checker) or the 2 ohms resistance. Connect the driver-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.
