Disabling & Activating Air Bag System
WARNING:
SIR SDM retains back-up voltage for about 10 seconds after disabling SIR system. Wait minimum of one minute after disabling SIR before servicing steering column components. Servicing steering column components before one minute period may cause accidental deployment of air bag and possible personal injury.
- Before proceeding, follow air bag service precautions. See SERVICE PRECAUTIONS . To disable air bag, turn ignition to LOCK position and remove key. Remove SIR fuse (air bag fuse) from fuse block. Remove Connector Position Assurance (CPA) clip from Yellow SIR harness connector at base of steering column. All SIR system connectors use CPA clips to ensure connector retention. Disconnect Yellow SIR connector. Wait at least one minute before working on vehicle.
- With SIR fuse removed and ignition on, AIR BAG indicator light will be on. This is normal operation for SIR system and does not indicate a fault code or system problem.
- To activate air bag system, ensure ignition is off. Connect Yellow SIR connector and CPA clip at base of steering column. Install SIR fuse. Turn ignition switch to RUN position. Observe AIR BAG indicator light. Light should flash 7 times and then go out. If AIR BAG indicator light does not function as described, a malfunction in air bag system exists.
