Air Bag Control Module: Service and Repair

SRS Unit Replacement

Removal
1. Disconnect the battery negative cable, and wait at least 3 minutes before beginning work.
2. Disconnect the airbag connectors and seat belt tensioner connectors.
3. Remove the front console.




4. Remove the cover (C), then disconnect the floor wire harness 18P (A) and 8P (B) connectors from the SRS unit(D).




5. Remove the three Torx bolts (A) from the SRS unit (B), then pull out the SRS unit.

Installation




1. Install the new SRS unit (C) with Torx bolts (D), then connect the floor wire harness 18P (A) and 8P (B) connectors to the SRS unit, push them into position until they click.

NOTE: When tightening the Torx bolts to the specified torque after replacement, be careful to turn them in so that their heads rest squarely on the brackets.

2. Reinstall the front console.
3. Reconnect the airbag connectors and seat belt tensioner connectors.
4. Reconnect the battery negative cable. If the IMA battery level gauge (BAT) displays no segments remove the No. 15 EPS (40 A) fuse from the under-hood fuse/relay box, then start the engine, and hold it between 3,500 rpm and 4,000 rpm without load (in Park or neutral) until the BAT displays at least three segments. Reinstall the No. 15 EPS (40 A) fuse.
5. After installing the SRS unit, confirm proper system operation: Turn the ignition switch ON (II); the SRS indicator should come on for about 6 seconds and then go off.
