Detection Condition

Warning

•  Detection conditions are for understanding the DTC outline before performing an inspection. Performing an inspection according to only the detection conditions may cause injury due to an operating error, or damage the system. When performing an inspection, always follow the inspection procedure.

Diagnostic Procedure

Step	Inspection		Action
1	INSPECT DRIVER-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. •  Remove the driver-side air bag module connector. (See DRIVER-SIDE AIR BAG MODULE REMOVAL/INSTALLATION.) •  Inspect the clock spring connector. (Corrosion, damage, and disconnected pins) •  Is there any malfunction of the clock spring connector?	Yes	Replace clock spring. (See CLOCK SPRING REMOVAL/INSTALLATION.)
		No	Go to the next step.
2	INSPECT CLOCK SPRING •  Remove the steering wheel. (See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION [L.H.D.].) (See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION [R.H.D.].) •  Remove the column cover. (See COLUMN COVER REMOVAL/INSTALLATION.) •  Remove the clock spring. (See CLOCK SPRING REMOVAL/INSTALLATION.) •  Inspect for continuity between clock spring connector terminals 1C—3A and 1D—3B. Note •  Inspect the clock spring wiring harness for continuity while shaking it. •  Is there continuity?	Yes	Go to the next step.
		No	Replace clock spring. (See CLOCK SPRING REMOVAL/INSTALLATION.)
3	INSPECT WIRING HARNESS BETWEEN SAS CONTROL MODULE AND CLOCK SPRING •  Remove the glove compartment cover. (See GLOVE COMPARTMENT COVER REMOVAL/INSTALLATION.) •  Disconnect the passenger-side air bag module connector. •  Disconnect the driver and passenger-side side air bag module connectors. •  Remove the headliner. (See HEADLINER REMOVAL/INSTALLATION.) (See HEADLINER REMOVAL/INSTALLATION [3HB].) •  Disconnect the driver and passenger-side curtain air bag module connectors. •  Disconnect the driver and passenger-side pre-tensioner seat belt connectors. •  Remove the rear console. (See REAR CONSOLE REMOVAL/INSTALLATION.) •  Disconnect the SAS control module connectors. •  Inspect the wiring harness between SAS control module connector terminal 3E and clock spring connector terminal 1D, and SAS control module connector terminal 3G and clock spring connector terminal 1C 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 clock spring. •  Is the wiring harness normal?	Yes	Go to the next step.
		No	Replace the wiring harness between the SAS control module and clock spring.
4	INSPECT THE WIRING HARNESS BETWEEN THE SAS CONTROL MODULE AND CLOCK SPRING FOR A SHORT CIRCUIT TO THE POWER SUPPLY •  Connect the negative battery cable. •  Switch the ignition to ON with SAS control module connector and clock spring connector disconnected. •  Measure the voltage of SAS control module connector terminals 3E and 3G. Note •  Measure the voltage while shaking the wiring harness between the SAS control module and clock spring. •  Is the voltage measured?	Yes	Replace the wiring harness between the SAS control module and clock spring.
		No	Go to the next step.
5	INSPECT DRIVER-SIDE AIR BAG MODULE •  Switch the ignition to off. •  Disconnect the negative battery cable and wait for 1 min or more. •  Connect the leads of the SST (Fuel and thermometer checker) or apply 2 ohms resistance to clock spring connector terminals 3A and 3B. •  Set the resistance of the SST (Fuel and thermometer checker) to the 2 ohms position. •  Except for the driver-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.) •  Perform the DTC inspection for the SAS control module using the M-MDS. (See DTC DISPLAY.) •  Are the same DTCs present?	Yes	Go to the next step.
		No	Replace the driver-side air bag module. (See DRIVER-SIDE AIR BAG MODULE REMOVAL/INSTALLATION.)
6	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.) •  Perform the DTC inspection for the SAS control module using the M-MDS. (See DTC DISPLAY.) •  Are the same DTCs present?	Yes	Replace the SAS control module. (See SAS CONTROL MODULE REMOVAL/INSTALLATION.)
		No	DTC troubleshooting completed.
