By working closely with our dealers and technicians, through the part restriction process, the General Motors team will gain a better understanding of any field concerns that may develop. Only the modules and components involved in a part restriction program require contact with the GM Technical Assistance Center (TAC) in order to obtain the necessary part. Parts such as antennas, cables, etc., are available through the normal parts ordering channels. Copyright 2020 General Motors LLC. All Rights Reserved. The TAC agent will no longer provide a part number back to the dealership when a VCIM is to be ordered. The replacement VCIM that the dealership will receive may have a different part number than the one currently installed in the vehicle. 1. If a replacement VCIM is deemed necessary, the TAC agent will no longer order the replacement part. Instead the dealer MUST use the ONE-TIME USE authorization number provided by TAC to order a replacement part through an Electronic Service Center (ESC). The ONE-TIME USE authorization number will be linked to the vehicle identification number (VIN) and CANNOT be used to order a replacement unit for any other VIN. Notice: The authorization number provided by TAC will expire after 30 days. 2. Order the replacement unit DIRECTLY from the following United States or Canadian ESC. 2.1. In the U.S. from the Specmo Enterprises ESC. Orders can be placed online at www.specmo.com or by phone. Contact them by phone at 800-545-7910 or 248-307-2570. 2.2.

Page 2 January, 2020 ESC Shipping and Core Return Information • The replacement VCIM is shipped using standard ground shipment unless otherwise specifically requested by the dealer. ⇒ If the replacement VCIM is not received within seven business days DO NOT contact TAC. For any concern regarding the non-receipt, ordering and returning of the core, or an unused/ unopened unit contact the ESC to which the order was placed. • A pre-paid return package label will be included for return shipment of the original VCIM. By returning the original VCIM, within the specified time noted in the documents contained within the packaging of the service replacement unit, the parts department will avoid a significant non-return core charge. Diagnosing - Replacement Reprogramming the OnStar® VCIM General Information Notice: If the diagnostic steps taken by the technician indicate the VCIM requires replacement, the service department personnel must contact TAC.
