After replacing the VCIM, it is essential to configure the new OnStar(R) system. Failure to configure the system will result in an additional
customer visit for repair. DO NOT press and hold the white dot or phone button on the keypad as it will not reset this version of the OnStar(R)
system and may result in a DTC being set. Use of the TIS2WEB and SPS applications, along with the Tech2(R), are required in order to perform
the VCIM configuration and setup procedure for this vehicle. The configuration and set-up procedure is now a two-step process which enables an
automated activation by the OnStar(R) Center, without a button press by the technician to the OnStar(R) Call Center.

Connect the Tech2(R) to the vehicle.
