Vehicles Involved
Involved vehicles have been identified by Vehicle Identification Number. Computer listings containing the complete Vehicle Identification Number,
customer name and address data have been prepared, and are being furnished to involved dealers with the program bulletin. The customer name and

program bulletin has no involved vehicles currently assigned.
These dealer listings may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle
registration data for any other purpose is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this listing
to the follow-up necessary to complete this program.
Parts Information

Service Procedure
Some vehicles involved in this customer satisfaction program may have had their instrument panel cluster (IPC) replaced prior to this program. As a
result, the replacement cluster may not need to be reprogrammed. To determine whether the IPC in the vehicle requires reprogramming, the following
procedure must be performed.
Important:
The Tech 2 diagnostic tool must be updated with software version 8.0, released July 2002, or newer, in order to perform the reprogramming.
