Diagnostic Procedure

Step

Inspection

Action

1

INSPECT PAD SWITCH 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 PAD switch connector.
(See PASSENGER AIR BAG DEACTIVATION (PAD) SWITCH REMOVAL/INSTALLATION.)

•  Inspect the PAD switch connector. (Corrosion, damage, and disconnected pins)

•  Is there any malfunction of the PAD switch connector?

Yes

Replace the PAD switch wiring harness.

No

Go to the next step.

2

INSPECT PAD SWITCH

•  Inspect the PAD switch.
(See PASSENGER AIR BAG DEACTIVATION (PAD) SWITCH INSPECTION.)

•  Is the PAD switch normal?

Yes

Go to the next step.

No

Replace the PAD switch.

(See PASSENGER AIR BAG DEACTIVATION (PAD) SWITCH REMOVAL/INSTALLATION.)

3

INSPECT WIRING HARNESS BETWEEN PAD SWITCH AND SAS CONTROL MODULE

•  Remove the column cover.
(See COLUMN COVER REMOVAL/INSTALLATION.)

•  Disconnect the clock spring.

•  Remove the glove compartment.
(See GLOVE COMPARTMENT REMOVAL/INSTALLATION.)

•  Disconnect the passenger-side air bag module connector.

•  Disconnect the driver and passenger-side side air bag module connectors.

•  Remove the C-pillar trim. (4SD)
(See C-PILLAR TRIM REMOVAL/INSTALLATION.)

•  Remove the headliner. (5HB, WGN)
(See HEADLINER REMOVAL/INSTALLATION.)

•  Disconnect the driver and passenger-side curtain air bag module connectors.

•  Remove the B-pillar lower trim. (4SD)
(See B-PILLAR LOWER TRIM REMOVAL/INSTALLATION.)

•  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 terminal 3H and PAD switch terminal D, SAS control module terminal 3F and PAD switch terminal C 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 PAD switch.

•  Is the wiring harness normal?

Yes

Go to the next step.

No

Replace the wiring harness between the SAS control module and PAD switch.

4

INSPECT WIRING HARNESS BETWEEN PAD SWITCH AND BODY GROUND

•  Inspect for continuity between PAD switch terminal E and body ground.

Note

•  Inspect for continuity while shaking the wiring harness between the PAD switch and body ground.

•  Is there continuity?

Yes

Go to the next step.

No

Replace the wiring harness between the PAD switch and body ground.

5

PERFORM SAS CONTROL MODULE DTC INSPECTION

•  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

Replace the SAS control module.

(See SAS CONTROL MODULE REMOVAL/INSTALLATION.)

No

DTC troubleshooting completed.
