Air Bag Control Module: Service and Repair

SAS unit Handling

Installing a connected SAS unit is dangerous. Movement generated during installation can cause the crash sensor inside the unit to send an electrical signal to the air bag modules. This will deploy the air bags, which may result in serious injury. Therefore, before connecting the SAS unit, firmly mount the unit to the vehicle.



GENERAL PROCEDURES

Before Servicing

1. Deactivate the audio antitheft system, it installed.
2. Turn the ignition switch to LOCK.
3. Disconnect the negative battery cable and wait for more than one minute to allow the backup power supply to deplete its stored power.
4. Remove the drive-side undercover and lower panel.





5. Disconnect the orange and blue clock spring connectors.
6. Remove the glove compartment.





7. Disconnect the orange and blue passenger-side air bag module connectors.
