If the OnStar(R) system DOES return to normal functionality, perform the following steps:
Install the Tech 2(R) and determine what generation hardware and software ID is in the vehicle.
If the vehicle is equipped with Generation 5 hardware and a software version 146, the VCIM should have the B1000 reprogramming performed as
described in Corporate Bulletin Number 04-08-46-004A. The system should be tested and if the concern returns, the VCIM should be replaced.
If Gen 5 with a software version OTHER than 146 or Gen 6 and above, the VCIM needs to be replaced and the system reconfigured.
You will need to call GM TAC in order to obtain a new VCIM. Refer to Corporate Bulletin Number 03-08-46-004C for more details on how to order a
new VCIM.
As with any OnStar(R) VCIM replacement, the OnStar(R) system must be reconfigured after replacement.
