Observe the following precautions when servicing air bag system:

Disable air bag system before attempting any repairs to steering column or components. Refer to DISABLING & ACTIVATING AIR BAG SYSTEM .
After disabling air bag system, Diagnostic Energy Reserve Module (DERM) retains back-up voltage for about 10 minutes. To avoid accidental air bag deployment, wait at least 10 minutes after disabling air bag system before working on vehicle components.
Always wear safety glasses when working around air bag system.
Always carry a live (undeployed) air bag with trim cover facing away from your body. This minimizes the chance of injury if air bag accidentally deploys.
Place a live (undeployed) air bag on a bench or other surface with trim cover facing up, away from surface. This will reduce motion of air bag if it accidentally deploys.
Never probe air bag inflator module connectors. Air bag may accidentally deploy.
Never attempt repair of any air bag system components. Replace any faulty components as required.
