For 1990-2009 cars

### Removal Procedure

Caution: When performing service on or around SIR components or SIR wiring, follow the procedure to temporarily disable SIR system. Refer to Disabling/Enabling SIR System in Restraints. Failure to follow procedures could result in possible air bag deployment, personal injury or otherwise unneeded SIR repairs.

1. Disable the SIR System. Refer to Disabling the SIR System in Restraints.
2. Remove the 4 screws (9) at the back of the steering wheel (1).

Caution: When carrying a live inflator module, make sure bag and trim cover are pointed away from body. Never carry the inflator module by wires or connector on underside of module. In case of an accidental deployment, 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 away from surface. Never rest a steering column on the steering wheel with inflator module face down and column vertical. This is necessary so that a free space is provided to allow air bag to expand in the unlikely event of accidental deployment. Otherwise, personal injury may result.

Important: Note the wire routing for assembly reference.

3. Position the inflator module (3) in order to gain access to the wire connectors.
4. Push in and rotate the horn contact lead (6) counterclockwise.
5. Remove the horn contact lead (6) from the steering column horn tower.
6. Remove the horn contact lead (6).
7. Remove the retainer (CPA) (10) from the SIR wiring connector.
8. Remove the SIR wiring connector from the inflatable restraint steering wheel module (3).
9. Disconnect the steering wheel control switch connector (7).
10. Remove the inflatable restraint steering wheel module (3).

### Installation Procedure

1. Connect the steering wheel switch connector, if equipped.
2. Install the retainer (CPA) (10) to the SIR wiring connector.
3. Route the horn contact lead (6) to the steering column horn tower.
4. Push the lead (6) into the horn tower.
5. Rotate the lead (6) clockwise to locked position.
6. Install the horn ground to lead (6).
7. Install the SIR connector and retainer (CPA).

Important: Do not pinch any wires.

8. Install the inflatable restraint steering wheel module (3) to the steering wheel (1).

First install the top surface of the module (3) in order to ease assembly and fit.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

9. Install the 4 screws (9) through the back of the steering wheel (1) to the inflator module (3).

Tighten
Tighten the screws to 3 N·m (27 lb in).

10. Enable the SIR system. Refer to Enabling the SIR System in Restraints.
