INSTALLATION - ORIGINAL PASSENGER AIR BAG MODULE

Installation is in the reverse order of removal. CAUTION: • Be careful not to damage the harness while installing.

• In case a malfunction is detected by the air bag warning lamp, reset with the self-diagnosis function and delete the memory by CONSULT−III.

• If a malfunction is still detected after the above operation, perform self-diagnosis to repair malfunctions.

Refer to SRC-12, "SRS Operation Check".

INSTALLATION - SERVICE REPLACEMENT PASSENGER AIR BAG MODULE

1. Install front passenger air bag module to the instrument panel assembly.

2. Install the instrument panel assembly. Refer to IP-12, "Removal and Installation".

3. Connect the front passenger air bag module harness connector to yellow 4-pin service replacement connector and fasten to mounting bracket.

Wiring Harness Modification

The front passenger air bag module originally installed in the vehicle uses direct-connect style harness connectors.

Service replacement passenger air bag modules use tab-locking style harness connectors. If the front passenger air bag module is replaced, or if the direct-connect harness connectors are damaged, the vehicle wiring harness must be modified to allow connection of the service replacement front passenger air bag module.

NOTE: The wiring harness modification is to be performed only if the vehicle is equipped with the original front passenger air bag module which uses direct-connect harness connectors. If the front passenger air bag module is to be replaced in a vehicle that has already had the service replacement front passenger air bag module installed, the wiring harness modification is not required.

1. Locate the yellow and orange direct-connect front passenger air bag module harness connectors.

2. Use wire cutters to cut back both previously used direct-connect front passenger air bag module harness connectors from the vehicle wiring harness approximately 50 mm (1.9 in) from the connectors.

3. Remove approximately 150 mm (5.9 in) of the vehicle harness covering from the cut end.

4. Slide a piece of dual-wall heat shrink tubing (provided in the passenger air bag module service kit) onto each wire of the previously used vehicle wiring harness.

5. Fold each wire back and insert into the end of the heat shrink tubing so that the end of the wire is approximately centered in the heat shrink tubing.

6. Use a heat gun to shrink the heat shrink tubing and seal the wire.

7. Use electrical tape to secure the modified circuits to the outside of the wiring harness.

8. Locate the front passenger air bag module service replacement connector that is taped back to the main harness. Unwrap the tape to access the yellow service replacement connector and remove the dust cover from the connector.

9. Connect service connector to front passenger air bag module.

10. Clip to service connector clipping point.

• After the work is completed, perform self-diagnosis to check that no malfunction is detected. Refer to SRC- 12, "SRS Operation Check".
