Diagnostic Procedure

Step

Inspection

Action

1
INSPECT DRIVER-SIDE SIDE AIR BAG SENSOR 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.
•  Switch the ignition to off.
•  Disconnect the negative battery cable and wait for 1 min or more.
•  Remove the B-pillar lower trim (driver's side).
•  Disconnect the driver-side side air bag sensor connector.
•  Inspect the driver-side side air bag sensor connector. (Corrosion, damage, and disconnected pins)
•  Is there any malfunction of the driver-side side air bag sensor connector?
Yes
Replace the driver-side side air bag sensor wiring harness.
No
Go to the next step.
2
INSPECT WIRING HARNESS BETWEEN SAS CONTROL MODULE AND DRIVER-SIDE SIDE AIR BAG SENSOR
•  Remove the column cover.
•  Disconnect the clock spring connector.
•  Remove the glove compartment cover.
•  Disconnect the passenger-side air bag module connector.
•  Disconnect the driver and passenger-side side air bag module connectors.
•  Remove the headliner.
•  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.
•  Disconnect the SAS control module connectors.
•  Inspect the wiring harnesses between SAS control module connector terminal 1L and driver-side side air bag sensor connector terminal A, and SAS control module connector terminal 1J and driver-side side air bag sensor 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 the driver-side side air bag sensor.
•  Is the wiring harness normal?
Yes
Go to the next step.
No
Replace the wiring harness between the SAS control module and the driver-side side air bag sensor.
3
INSPECT THE WIRING HARNESS BETWEEN THE SAS CONTROL MODULE AND DRIVER-SIDE SIDE AIR BAG SENSOR 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 sensor connector disconnected.
•  Measure the voltage of SAS control module connector terminals 1L and 1J.
Note
•  Measure the voltage while shaking the wiring harness between the SAS control module and the driver-side side air bag sensor.
•  Is the voltage measured?
Yes
Replace the wiring harness between the SAS control module and the driver-side side air bag sensor.
No
Replace the driver-side side air bag sensor, then go to the next step.
4
PERFORM SAS CONTROL MODULE DTC INSPECTION
•  Switch the ignition to off.
•  Disconnect the negative battery cable and wait for 1 min or more.
•  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.
•  Perform the DTC inspection for the SAS control module using the M-MDS.
•  Are the same DTCs present?
Yes
Replace the SAS control module.
No
DTC troubleshooting completed.
