Telephone/Telematic Control Module -J526-, replacing and reconfiguring: Notes
2004 Audi A6 BaseSECTION Notes
After replacing the Telephone/Telematic Control Module, the OnStar® system needs to be reconfigured as described below. Have the VIN and customer details on hand.
NOTE:
- DO NOT exchange Telephone/Telematic Control Modules between vehicles!. Each module contains specific Station Identification (STID) and Electronic Serial Number (ESN) data unique to the VIN. This data is used by OnStar® and National Cellular Telephone Network to identify the vehicle and administer the customer's account.
- Failure to reconfigure the control module after replacement will prevent OnStar® services and features from functioning, and will result in a customer return for repair.
- Always replace the emergency (back-up) battery when replacing the Telephone/Telematics Control Module.
