20. Install the connector to the sensor.
21. From the technicians point of view, the FRONT of the sensor will have: A pin hole (3) for the centering pin (note location of the pin hole) A flush rotor flange cuff (5) An alignment mark (4) for installation A foam ring (6)
22. From the technicians point of view, the BACK of the sensor will have: Double D flats (1) An alignment tab (2) for installing into the adapter and bearing assembly. Important: If reusing the existing sensor, you must align the marks on the flush rotor flange cuff before installation. The alignment mark must stay aligned until the sensor is seated into the adapter and bearing assembly. If installing a new sensor, it will come with a pin installed in the sensor. Do not remove the pin until the sensor is seated. If the new sensor did not come with a pin installed, you must reorder a new sensor.
23. Looking at the FRONT of the sensor, align the sensor with the steering shaft and install into the adapter and bearing assembly.
24. Install the connector to the sensor.

Inflatable Restraint Steering Wheel Module Coil Centering

Note. The new SIR coil assembly will be centered. Improper alignment of the SIR coil assembly may damage the unit, causing an inflatable restraint malfunction.

Important: If double wire harness strap is installed onto the wire harness assembly and column, you must reuse the holder for the wire straps during installation.

Remove the wire harness strap(s) where necessary.

1. Verify the following conditions before centering the SIR coil: The wheels on the vehicle are straight ahead. The block tooth (1) of the steering shaft assembly is in the 12 o'clock position. The ignition switch is in the LOCK position.
2. If the front (5) of the SIR coil has a centering window (4), and the back side (2) includes a spring service lock (1), perform the following steps: Hold the SIR coil with the face up. While depressing the spring service lock, rotate the coil hub clockwise until the coil ribbon stops. Rotate the coil hub slowly, counterclockwise, until the centering window appears yellow and both arrows (3) line up. Release spring service lock between the locking tab. The SIR coil is now centered. Align the centered SIR coil with the horn tower and slide onto the steering shaft assembly.
3. If the front (4) of the SIR coil has a centering window (3), and the back side (1) includes NO spring service lock, perform the following steps: Hold the SIR coil with the face up. Rotate the coil hub clockwise until the coil ribbon stops. Rotate the coil hub slowly, counterclockwise until the centering window appears yellow and both arrows (2) line up. This is the CENTER position. While holding the coil hub in the CENTER position, align the SIR coil with the horn tower and slide onto the steering shaft assembly.
4. If the front side (3) of the SIR coil has NO centering window, but the back side (2) includes a spring service lock (1), perform the following steps: Hold the SIR coil with the back side up. While depressing the spring service lock, rotate the coil hub in the direction of the arrow (4) until the coil ribbon stops. Still pressing the spring service lock, rotate the coil hub in the opposite direction 2 1/2 revolutions. Release the spring service lock between locking tabs. The SIR coil is now centered. Align the centered SIR coil with the horn tower and slide onto the steering shaft assembly.
5. For the front side (2) of the SIR coil has NO centering window, and the back side (1) includes NO spring service lock, perform the following steps: Hold the SIR coil with the face up. Rotate the coil hub in the direction of the arrow until the coil ribbon stops. Rotate the coil hub, slowly, counterclockwise, for 2 1/2 revolutions. This is the CENTER position. While maintaining the coil hub in the CENTER position, align the centered SIR coil with the horn tower and slide onto the steering shaft assembly.
6. If double wire harness strap is installed onto the wire harness assembly and column, you must route the wires up against the steering column. One wire harness strap will surround one lead from the coil to the steering column. The other wire harness strap will surround all leads to the steering column.

Steering Wheel and Column Description and Operation

The steering wheel and column has 4 primary functions

1. Vehicle steering
2. Vehicle security
3. Driver convenience
4. Driver safety

Vehicle Steering

The steering wheel is the first link between the driver and the vehicle. The steering wheel is fastened to a steering shaft within the column. At the lower end of the column, the intermediate shaft connects the column to the steering gear.

Vehicle Security on Some Vehicle Models

Theft deterrent components are mounted and designed into the steering column. The following components allow the column to be locked in order to minimize theft

1. The ignition switch
2. The manual transmission steering column lock
3. The ignition cylinder

Driver Convenience

The steering wheel and column may also have driver controls attached for convenience and comfort. The following controls may be mounted on or near the steering wheel or column.

1. The turn signal switch
2. The hazard switch
3. The headlamp dimmer switch
4. The wiper/washer switch
5. The horn pad/cruise control switch
6. The redundant radio/entertainment system controls
7. The tilt or tilt/telescoping functions
8. The navigation/OnStar® features
9. The HVAC controls

Driver Safety

The energy-absorbing steering column compresses in the event of a front-end collision, which reduces the chance of injury to the driver. The mounting capsules break away from the mounting bracket in the event of an accident.
