Step

Inspection

Action

1

• Is the malfunction diagnosis performed using the flowchart? (See FLOWCHART [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM)].)

Yes

Go to the next step.

No

Re-perform the malfunction diagnosis using the flowchart. (See FOREWORD [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM)].)

WARNING:

• Handling the component parts improperly can accidentally operate (deploy) the air bag modules and pre-tensioner seat belts, 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 [TWO-STEP DEPLOYMENT CONTROL SYSTEM].) (See AIR BAG SYSTEM SERVICE CAUTIONS [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

• Switch the ignition off.

• Disconnect the negative battery cable and wait for 1 min or more.

  (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

• Remove the back trim.

  (See BACK TRIM REMOVAL/INSTALLATION.)

• Are all SAS control module connectors securely connected?

Yes

Go to the next step.

No

Reconnect the SAS control module connector properly, then go to Step 4.

3

• Remove the column cover.

  (See COLUMN COVER REMOVAL/INSTALLATION.)

• Disconnect the clock spring connector.

• Disconnect the driver and passenger-side lap pre-tensioner seat belt connectors.

  (See SEAT BELT REMOVAL/INSTALLATION.)

• Verify the condition of the detector bars of the SAS control module connectors. (Corrosion, damage, and disconnected pins)

• Are the detector bars of the SAS control module connectors normal?

Yes

Go to the next step.

No

Replace the air bag harness.

4

• Connect the SAS control module connectors.

• Reconnect all disconnected connectors.

• Connect the negative battery cable.

  (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

• Switch the ignition ON (engine off or on).

• Clear the DTC for the SAS control module using the M-MDS.

  (See CLEARING DTC [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM)].)

• Perform the DTC inspection for the SAS control module using the M-MDS.

  (See DTC INSPECTION [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM)].)

• Is the same DTC present?

Yes

Repeat the inspection from Step 1.

• If the malfunction recurs, replace the SAS control module.

  (See SAS CONTROL MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

No
