SIR component location affects how a vehicle should be serviced. There are parts of the SIR system installed in various locations around a vehicle. To find the location of the SIR components refer to SIR Identification Views . There are several reasons for disabling the SIR system, such as repairs to the SIR system or servicing a component near or attached to an SIR component. There are several ways to disable the SIR system depending on what type of service is being performed. The following information covers the proper procedures for disabling/enabling the SIR system. SIR Service Precautions Caution: When performing service on or near the SIR components or the SIR wiring, the SIR system must be disabled. Failure to observe the correct procedure could cause deployment of the SIR components. Serious injury can occur. Failure to observe the correct procedure could also result in unnecessary SIR system repairs. The inflatable restraint sensing and diagnostic module (SDM) maintains a reserved energy supply. The reserved energy supply provides deployment power for the air bags if the SDM loses battery power during a collision. Deployment power is available for as much as 1 minute after disconnecting the vehicle power. Waiting 1 minute before working on the system after disabling the SIR system prevents deployment of the air bags from the reserved energy supply. General Service Instructions The following are general service instructions which must be followed in order to properly repair the vehicle and return it to its original integrity: • Do not expose inflator modules to temperatures above 65°C (150°F). • Verify the correct replacement part number. Do not substitute a component from a different vehicle. • Use only original GM replacement parts available from your authorized GM dealer. Do not use salvaged parts for repairs to the SIR system.

1988-94 Models See Figures 1 and 2 1. Remove the steering wheel. Fig. Fig. 1: Installing the lock cylinder Fig. Fig. 2: Ignition switch 2. Remove the turn signal switch. It is not necessary to completely remove the switch from the column. Pull the switch rearward far enough to slip it over the end of the shaft, but do not pull the harness out of the column. 3. Turn the lock to Run. 4. If necessary, remove the ignition key. 5. If equipped, remove the buzzer switch assembly. 6. Remove the lock retaining screw and remove the lock cylinder.

Failure to do so could result in possible air bag deployment, personal injury or unneeded SIR system repairs. When carrying a live inflator module, make sure that the bag and trim cover are pointed away from you. Never carry the inflator module by the wires or connector on the underside of the module. In case of accidental deployment, the bag will then deploy with minimal chance of injury. When placing a live inflator module on a bench or other surface, always face the bag and trim cover up, away from the surface. 1. Disconnect the negative battery cable and disable the SIR system. 2. Remove the upper and lower shroud, air bag module and the steering column.
