Telephone/Telematic Control Module -J526-, replacing and reconfiguring: Notes

WARNING: This page is about a different car, the 2004 Audi S4, 2004 Audi A4, 2003 Audi A4, and 2002 Audi A4. However, it is still accessible from the selected car via links, so may be relevant.

After replacing the Telephone/Telematic Control Module, the OnStar(R) system needs to be reconfigured and the emergency battery must be switched on 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(R) 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(R) 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.
