Circuit Description

WARNING: This page is about a different car, the 2007 GMC Sierra and 2007 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.

This DTC is set as current in all vehicle communication interface module (VCIM) service parts and has been implemented as a reminder to contact the OnStar® Call Center to properly update the customer's account once the new module has been installed. This call is initiated automatically after the installation of the replacement VCIM, and the completion of the Setup New VCIM procedure on the scan tool. No external circuits are involved.
