Inflatable Restraint Coil Centering - Off Vehicle Column Shift and Floor Shift
Centering Procedure
Notice: The new SRS coil assembly will be centered. Improper alignment of the
SRS coil assembly may damage the unit, causing a supplemental restraint malfunction.
- Verify
the following before centering the SRS coil assembly:
• | 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 or J 42640
is installed in the
upper tilt head assembly. |
- If the front (5)
of the SRS coil assembly has a centering window (4), and on the back
side (2) a spring service lock (1), perform the following steps:
2.1. | Hold the coil assembly 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, counter clockwise, until the centering
window appears yellow and both arrows (3) line up. |
2.4. | Release spring service lock between the locking tab. The SRS coil
is now centered. |
2.5. | Align the centered SRS coil assembly with the horn tower and slide
onto the steering shaft assembly. |
- If the front (4)
of the SRS coil has a centering window (3) and no spring service lock
on the back side (1), perform the following steps:
3.1. | Hold the coil assembly with the face up. |
3.2. | Rotate the coil hub clockwise until the coil ribbon stops. |
3.3. | Rotate the coil hub slowly, counter clockwise until the centering
window appears yellow and both arrows (2) line up. This is center position. |
3.4. | While holding the coil hub in center position, align the SRS coil
assembly with the horn tower and slide onto the steering shaft assembly. |
- If no centering window
is present on the front side (3) of the SRS coil assembly, but a spring
service lock (1) is on the back side (2), perform the following
steps:
4.1. | Hold the SRS coil assembly with the back side up. |
4.2. | While depressing the spring service lock, rotate the coil hub
counter clockwise 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 SRS
coil is now centered. |
4.5. | Align the centered SRS coil assembly with the horn tower and slide
onto the steering shaft assembly. |
- For no centering window
on the front side (2) of the SRS coil assembly and no spring service
lock on the back side (1), perform the following steps:
5.1. | Hold the coil assembly with the face up. |
5.2. | Rotate the coil hub clockwise until the coil ribbon stops. |
5.3. | Rotate the coil hub, slowly, counter clockwise, for 2 ½
revolutions. This is center position. |
5.4. | While maintaining the coil hub in center position, align the centered
SRS coil assembly with the horn tower and slide onto the steering shaft assembly. |
