REMOVAL
WARNING:
- If replacing a deployed air bag module, always replace the air bag electronic crash sensor (ECS) module.
- Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module.
- Carry a live air bag module with the air bag and trim cover pointed away from your body. This will reduce the risk of injury in the event of an accidental deployment.
- Do not set a live air bag module down with the trim cover face down.
- After deployment, the air bag surface can contain deposits of sodium hydroxide, a product of the gas generant combustion that is irritating to the skin. Wash your hands with soap and water afterwards.
- Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.
- Air bag modules with discolored or damaged trim covers must be replaced, not repainted.
NOTE:
- Vehicles with speed control only shown, all others are similar.
- Repair is made by replacement only. If a part is replaced and the new part does not correct the condition, install the original part and perform the diagnostic procedure again.
1. Prepare the vehicle for driver air bag module removal.
1 WARNING: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking components near the front or side air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood latches.
The side air bag sensors are located at or near the base of the B-pillar.
To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped).
Disconnect the battery ground cable and wait at least one minute.
2 WARNING: To reduce the risk of serious personal injury, read and follow all warnings, notes, and instructions in the supplemental restraint system (SRS) deactivation/reactivation procedure.
Deactivate the supplemental restraint system (SRS).
2. Remove the driver air bag module.
1 Remove the two back cover plugs.
2 Remove the two driver air bag module screws.
3 Disconnect the horn electrical connector.
4 Disconnect the clockspring electrical connector.
5 Remove the driver air bag module.
3. Remove the restraint system diagnostic tool from the vehicle harness side of the clockspring electrical connector at the base of the steering column.
4. Connect the clockspring electrical connector at the base of the steering column.
5. Attach the restraint system diagnostic tool to the clockspring electrical connector at the top of the steering column.
6. Connect the battery ground cable.
7. With the restraint system diagnostic tools installed at all deployable devices, prove out the supplemental restraint system (SRS). Prove Out Procedure
8. Disconnect the battery ground cable and wait at least one minute.
INSTALLATION
WARNING: To reduce the risk of serious personal injury, read and follow all warnings, cautions and notes at the beginning of the removal procedure.
1. Disconnect the battery ground cable and wait at least one minute.
2. Remove the restraint system diagnostic tools from the clockspring electrical connectors at the top of the steering column.
3. Install the driver air bag module.
1 Connect the horn electrical connector.
2 Connect the driver air bag module electrical connector.
3 Position the driver air bag module into the steering wheel.
4 Install the two bolts.
5 Install the two steering wheel back cover plugs.
4. Connect the battery ground cable.
5. With the restraint system diagnostic tools still installed at the remaining deployable devices, prove out the supplemental restraint system (SRS). Prove Out Procedure
6. WARNING: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking components near the front or side air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood latches.
Please refer to the appropriate Component or System to determine location of the front air bag sensors.
The side impact sensors are located at or near the base of the B-pillar.
To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped).
Disconnect the battery ground cable and wait at least one minute.
7. Restore the vehicle to operating condition.
1 WARNING: To reduce the risk of serious personal injury, read and follow all warnings, cautions, notes, and instructions in the supplemental restraint system (SRS) deactivation/reactivation procedure.
Reactivate the supplemental restraint system (SRS).
2 WARNING: The restraint system diagnostic tool is for restraint system service only. Remove from the vehicle prior to road use. Failure to remove could result in injury and possible violation of vehicle safety standards.
With all the restraint system diagnostic tools removed, prove out the supplemental restraint system (SRS). Prove Out Procedure
