SERVICE PROCEDURE
- Remove driver air bag.

NOTE: VEHICLES MAY BE EQUIPPED WITH STEERING WHEELS THAT UTILIZE EITHER COPPER OR SILVER HORN CONTACTS. FOR COPPER CONTACTS PROCEED WITH STEP 3, FOR SILVER CONTACTS SKIP TO STEP 4.
- Wipe the four (4) copper contacts on the steering wheel with the plastic scouring pad until the copper rivets appear shiny.
- Wipe the four (4) horn contact points on the rear of the air bag module with the plastic scouring pad and PM-4 cleaner to remove any residue.
