2001 and Older Model Year Vehicles (Except Saab Vehicles)

2001 and Older Model Year Vehicles (Except Saab Vehicles)

Important:
2001 and older model year vehicles require the removal of the battery power from the OnStar(R) vehicle interface unit (VIU) to eliminate the possibility of an inadvertent OnStar(R) or emergency/airbag call.

1. Locate and gain access to the OnStar� VIU. Refer to OnStar Vehicle Interface Unit Replacement in SI.

Important:
Complete removal of the VIU is usually not required. Perform only the steps required to gain access to the C2 32-way blue connector. Residing in the C2 connector are the battery positive (+) circuits. Removal of the C2 connector will deactivate the unit and eliminate the possibility of an inadvertent OnStar(R) or emergency/airbag call.

2. Disconnect the C2 32-way blue connector from the VIU and tape the connector to a secure location. Refer to Cellular Communications Connector End Views and related schematics in SI, if required.

Important:
DO NOT perform the OnStar(R) reconfiguration and/or programming procedure.

3. Secure the VIU in its original brackets and/or mounting locations and reinstall the VIU and interior components that were removed to gain access to the VIU. Refer to OnStar Vehicle Interface Unit Replacement in SI.
