99-05 Year Vehicles, Equipped with Three Button OnStar Systems - kw blue cellular center coax data DTC handsfree information inoperative mute phone VCIM VCU VIU noconnect OPC

The following diagnosis might be helpful if the vehicle exhibits the described symptoms in the PI.

1999 through current model year vehicles, equipped with three button OnStar systems.

OnStar deactivates vehicles where the customer has either chosen not to renew their OnStar subscription after expiration, or when the initial activation has never taken place. As a part of the OnStar renewal communications, customers are notified that the OnStar system in their vehicle will be deactivated unless they elect to renew the account.

After the vehicle has been successfully deactivated,customers will experience the following when attempting to contact OnStar from their vehicle:

Blue Star key:

the customer will be connected to a dedicated sales team who can sell an OnStar subscription and reactivate the vehicle (depending on the type of OnStar hardware in the vehicle, the customer may first hear a demonstration message stating there is no current OnStar subscription for the vehicle, and directing the customer what to do to activate services.)

Emergency key:

when a customer depresses this key, a demo message will be played indicating the service has been deactivated (on 1999 models, the operation of this key does not change with deactivation.)

**NOTE: When successfully deactivated, the OnStar system will not attempt to connect to the OnStar Center if the vehicle's front airbags deploy.

Certain vehicles that have never had an active OnStar account may mimic the symptoms of a cellular or vehicle hardware concern, once they have been deactivated as they may not be able to establish a connection to the OnStar Center.

When normal published diagnostic procedures do not indicate a possible cause for the no connect concern, the vehicle may have been deactivated. For deactivated vehicles, a no connect response should be considered normal operation. Further diagnosis and subsequent repair is only necessary should the customer elect to become an active OnStar subscriber.
