Inflatable Restraint Coil Centering - Off Vehicle Column Shift And Floor Shift
Notice: 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 before centering the inflatable restraint steering
wheel module 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. |
- If the front (5)
of the inflatable restraint steering wheel module coil has a centering window (4),
and on the back side (2) a spring service lock (1), perform
the following steps:
2.1. | Hold the inflatable restraint steering wheel module 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 spring service lock between the locking tab. The inflatable
restraint steering wheel module coil is now centered. |
2.5. | Align the centered inflatable restraint steering wheel module
coil with the horn tower and slide onto the steering shaft assembly. |
- If the front (4)
of the inflatable restraint steering wheel module coil has a centering window (3)
and no spring service lock on the back side (1), perform the following
steps:
3.1. | Hold the inflatable restraint steering wheel module 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 inflatable
restraint steering wheel module coil with the horn tower and slide onto the
steering shaft assembly. |
- If no centering window
is present on the front side (3) of the inflatable restraint steering
wheel module coil, but a spring service lock (1) is on the back side (2),
perform the following steps:
4.1. | Hold the inflatable restraint steering wheel module 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 2 ½ revolutions. |
4.4. | Release the spring service lock between locking tabs. The inflatable
restraint steering wheel module coil is now centered. |
4.5. | Align the centered inflatable restraint steering wheel module
coil with the horn tower and slide onto the steering shaft assembly. |
- For no centering window
on the front side (2) of the inflatable restraint steering wheel module
coil and no spring service lock on the back side (1), perform the
following steps:
5.1. | Hold the inflatable restraint steering wheel module 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 2 ½
revolutions. This is the CENTER position. |
5.4. | While maintaining the coil hub in the CENTER position, align the
centered inflatable restraint steering wheel module coil with the horn tower
and slide onto the steering shaft assembly. |
