- Disabling the SIR System
DISABLING THE SIR SYSTEMSCAUTION: When performing service on or around SIR components or SIR wiring, follow the procedures listed below to temporarily disable the SIR system. Failure to follow procedures could result in possible air bag deployment, personal Injury, or otherwise unneeded SIR system repairs.
The DERM can maintain sufficient voltage to cause a deployment for up to 2 minutes after the ignition switch is turned "OFF" or the battery is disconnected. Many of the service procedures require disconnection of the "AIR BAG" fuse and the inflator module circuits from the deployment loops to avoid an accidental deployment.
REMOVE OR DISCONNECT
^ Turn the steering wheel so that the vehicle's wheels are pointing straight ahead.
^ Turn the ignition switch to "LOCK" and remove key.
1. "AIR BAG" fuse from I/P fuse block.
2. Steering column filler panel.
3. Connector position assurance (CPA) retainer and yellow 2-way SIR connector at base of steering column.
Important
^ With the "AIR BAG" fuse removed and ignition switch "ON", the "AIR BAG" warning lamp will be "ON". This is normal operation and does not indicate an SIR system malfunction.
