Install the CIM fastener.
Tighten: Tighten the fastener to 10 N.m (89 lb. in.).

IMPORTANT: After replacing the vehicle communication interface module, you must reconfigure the OnStar® system. Failure to reconfigure the system will result in an additional customer visit for repair. In addition, pressing and holding the white dot button on the keypad will NOT reset this version of the OnStar® system. This action will cause a DTC to set.

Reconfigure the OnStar® system. Refer to OnStar Reconfiguration (Gen 6) or OnStar Reconfiguration (Gen 6.1) .
