ON-VEHICLE SERVICE
SERVICE PRECAUTIONS
The DERM can maintain sufficient voltage to cause a deployment for 10 minutes after the ignition switch is turned off and the battery is disconnected. Many of the service procedures require disconnection of the SIR fuse and inflator module from the deployment loop to avoid an accidental deployment. Diagnostic procedures do not normally require fuse removal or disconnection of the inflator module. Always refer to GM service procedures for diagnosis.
CAUTION: When performing service on or around the SIR components or SIR wiring, follow the procedures listed below to temporarily disable the SIR system. Refer to appropriate service manual procedures. Failure to follow procedures could result in possible air bag deployment, personal injury, or otherwise unneeded SIR repairs.

1. Turn ignition switch to "OFF".
