Vibe L4-1.8L (2008)
Communications Control Module: Service and Repair
Communication Interface Module Replacement
Removal Procedure
Important: The vehicle communication interface module (VCIM) has a specific set of unique numbers that tie the module to each vehicle.
These numbers, the 10-digit station identification and the 11-digit electronic serial number, are used by the National Cellular Network
and OnStar(R) to identify the specific vehicle. Because these numbers are tied to the vehicle identification number of the vehicle, you
must never exchange these parts with those of another vehicle.
Caution: Refer to Battery Disconnect Caution (See: Starting and Charging/Battery/Service Precautions/Technician Safety Information/Battery
Disconnect Caution).
1. Disconnect the battery ground cable.
2. Position the seat to the most rearward position.
3. Disconnect two vehicle communication interface module electrical connectors (1).
4. Disconnect the cellular antenna and the navigation radio antenna connectors (1).
