Caution: The new SIR coil assembly will be centered. Improper alignment of the SIR coil assembly may damage the unit, causing an inflatable restraint malfunction.
- 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 assembly is in the LOCK position. |
- If the front (5) of the SIR coil has a centering window (4), and the back side (2) has a spring service lock (1), perform the following steps:
2.1. | Hold the coil with the face up. |
2.2. | While depressing the spring service lock, rotate the coil hub clockwise until the coil ribbon stops. |
2.3. | Rotate the coil hub slowly, counterclockwise, until the centering window appears yellow and both arrows (3) line up. |
2.4. | Release the spring service lock between the locking tab. The SIR coil is now centered. |
2.5. | Align the centered SIR coil with the horn tower and slide onto the steering shaft assembly. |
- If the front (4) of the SIR coil has a centering window (3) and the back side (1) has NO spring service lock, perform the following steps:
3.1. | Hold the coil with the face up. |
3.2. | Rotate the coil hub clockwise until the coil ribbon stops. |
3.3. | Rotate the coil hub slowly, counterclockwise until the centering window appears yellow and both arrows (2) line up. This is the CENTER position. |
3.4. | While holding the coil hub in the CENTER position, align the coil with the horn tower and slide the coil onto the steering shaft assembly. |
- If no centering window is present on the front side (3) of the SIR coil, but a spring service lock (1) is on the back side (2), perform the following steps:
4.1. | Hold the coil with the back side up. |
4.2. | While depressing the spring service lock, rotate the coil hub in the direction of the arrow (4) until the coil ribbon stops. |
4.3. | Still pressing the spring service lock, rotate the coil hub in the opposite direction 2½ revolutions. |
4.4. | Release the spring service lock between the locking tabs. The SIR coil is now centered. |
4.5. | Align the centered coil with the horn tower and slide the coil onto the steering shaft assembly. |
- If no centering window appears on the front side (2) of the SIR coil and no spring service lock exists on the back side (1), perform the following steps:
5.1. | Hold the coil with the face up. |
5.2. | Rotate the coil hub in the direction of the arrow until the coil ribbon stops. |
5.3. | Rotate the coil hub, slowly, counterclockwise, for 2½ revolutions. This is the CENTER position. |
5.4. | While maintaining the coil hub in the CENTER position, align the centered coil with the horn tower and slide the coil onto the steering shaft assembly. |
