INFLATABLE RESTRAINT STEERING WHEEL MODULE
REMOVE OR DISCONNECT
1. Disable SIR system. Refer to "Disabling the SIR System".
2. Rotate the steering wheel so that the side of the SIR module is at the 12 o'clock position.
3. Insert a screwdriver into one of the four holes on the back of the steering wheel.
4. Pull the screwdriver handle away from the steering column to release the leaf spring from the notched pin.
5. Repeat the steps mentioned above for the other three attached locations.
6. Tilt the inflator module rearward to gain access to the electrical connection.
7. The electrical connector from the inflator module.
8. The inflatable restraint module from the steering wheel.
CAUTION: When carrying a live inflatable restraint steering wheel module, make sure the bag opening is pointed away from you. Never carry the inflatable restraint steering wheel module by the wires or electrical connector on the underside of it. In case of an accidental deployment, the bag will then deploy with minimal chance of Injury. When placing a live inflatable restraint steering wheel module on a bench or other surface, always face the bag and trim cover up, away from the surface. Never rest a steering column on the steering wheel with the inflatable restraint steering wheel module face down and steering column vertical. This is necessary so that a free space is provided to allow the air bag to expand in the unlikely event of accidental deployment.
INSTALL OR CONNECT
1. The inflatable restraint module to the steering wheel.
2. The electrical connector.
- Ensure that the wiring is not exposed or trapped between the inflatable restraint steering wheel module and the steering wheel.
3. Place the inflator module onto the steering wheel and press module into the retaining tabs until the module is secured properly in all 4 retaining locations.
4. Rotate the steering wheel back into the straight position.
5. Enable SIR system. Refer to "Enabling the SIR System".
