Removal Procedure
WARNING: This page is about a different car, the 2003 Saturn Ion 3, 2003 Saturn Ion 2, and 2003 Saturn Ion 1. However, it is still accessible from the selected car via links, so may be relevant.
- Remove the rear shelf trim. Refer to Trim Panel Replacement - Rear Window Shelf (Early Production) in Interior Trim.
- Remove the interface module from the bracket by pulling back on the bracket tabs.
- Disconnect the electrical harnesses and the antenna cable.
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® 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.
IMPORTANT:
This vehicle may be equipped with one of two versions of the OnStar® System.
Early production vehicles will have the generation 4 module and later productions will have the generation 5 module. The two modules cannot be interchanged. The generation 4 module can be identified by the use of three connector cavities. The generation 5 module uses four connector cavities. In addition, the station identification and the electronic serial number information on the generation 5 label cannot be used to update customer account information if the module is replaced. You must use a scan tool to access this information.
