Removal & Installation
Before servicing the vehicle, refer to the Precautions Section.
NOTEWhen performing service on or near the SRS components, or SRS wiring the SRS must be disabled. Failure to observe the correct procedure could cause deployment of the SRS components. Serious injury can occur.
- Position the steering wheel so the front wheels are in the straight ahead position.
- Be sure the ignition switch is in the OFF position.
Disconnect the negative battery cable.
NOTEThe SDM may have more than one fused power input. To ensure that there is no unwanted SRS deployment, personal injury, or unnecessary SRS system repairs, remove all fuses supplying power to the SDM. With all SDM fuses removed and the ignition switch in the ON position, the AIR BAG warning indicator will illuminate. This is normal and does not indicate a SRS system malfunction.
- Locate and remove the fuses supplying power to the SDM.
- Wait one minute before working on the vehicle.

NOTEDo not apply power to the actuator when it is removed from the HVAC module.

Recalibrate the actuator.
NOTEThe preferred method to recalibrate the actuator is with a scan tool. Using the GM diagnostic scan tool or aftermarket equivalent reprogram the actuator. Be sure to follow the scan tool manufacturer-s directions.
- If a scan tool is not available, Clear all DTC codes. Position the ignition switch in the OFF position. Remove the HVAC/ECAS fuse for a minimum of ten seconds. Install the fuse. Start the vehicle. Wait forty seconds for the HVAC control module to recalibrate. Verify that no DTC codes have set.
- Enable the SRS system. Be sure the ignition switch is in the OFF position. Install the fuses. Connect the negative battery cable. Turn the ignition switch to the ON position. If the system is operating properly the AIR BAG indicator will flash.
