Inflatable Restraint Steering Wheel Module Coil Replacement - Off Vehicle. Chevrolet Metro 1998

For 1990-2009 cars

### Removal Procedure

Important: In the event that deployment occurs, inspect the supplemental inflatable restraint (SIR) coil assembly for any signs of scorching, melting, or other damage due to excessive heat. If you find damage to the coil assembly, replace the coil assembly. Refer to Inflatable Restraint Steering Wheel Module Coil Replacement in Inflatable Restraint Coil Replacement in SIR.

Caution: This vehicle is equipped with a Supplemental Inflatable Restraint (SIR) System. Failure to follow the correct procedure could cause the following conditions:

• | Air bag deployment

• | Personal injury

• | Unnecessary SIR system repairs

In order to avoid the above conditions, observe the following guidelines:

• | Refer to SIR Component Views in order to determine if you are performing service on or near the SIR components or the SIR wiring.

• | If you are performing service on or near the SIR components or the SIR wiring, disable the SIR system. Refer to Disabling the SIR System.

1. Disable the supplemental inflatable restraint (SIR). Refer to Disabling the SIR System in Supplemental Inflatable Restraints.

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

2. Disconnect the negative battery cable.
