TAKING THESE ACTIONS WILL HELP AVOID INADVERTENT AIRBAG DEPLOYMENTS
When making vehicle repairs to or near the Supplemental Inflatable Restraint (SIR) system, technicians need to take precautions to avoid inadvertent airbag deployments, which are both dangerous and costly. Any service work to the SIR system, SIR wiring, or a component near or attached to an SIR component should be performed with the ignition off and the SIR system disabled.
To view airbag locations within a vehicle, refer to the Master Electrical Component List in the appropriate Service Information document. Before performing service on or around SIR components or wiring, refer to the SIR Identification Views in the appropriate Service Information document to find the location of the SIR components.
TO DISABLE THE SIR SYSTEM BY DISCONNECTING THE NEGATIVE BATTERY CABLE:
1. Turn the steering wheel so that the vehicle’s wheels are pointing straight ahead.
2. Place the ignition in the Off position.
3. Disconnect the negative battery cable from the battery.
4. Wait 2 minutes before working on the system.
TIP: Whenever a vehicle requires repair of the SIR system as well as another vehicle system, repair the SIR system first before repairing the other system.
