This bulletin is being revised to correct parts and claim information. Please discard Product Campaign Bulletin Number 99088, dated February, 2000.
General Motors has decided to conduct a Voluntary Emission Campaign involving certain 1995-96 Chevrolet Cavalier and Pontiac Sunfire (J car) model
vehicles. These vehicles may exhibit symptoms resulting in the illumination of the Check Engine light or the engine runs rough. If these symptoms are
ignored, the engine may stall and may not be able to be restarted. This may be due to moisture entering the Powertrain Control Module (PCM), as a
result of corrosion.
To correct this condition, dealers are to clean and/or replace the Powertrain Control Module (PCM), then seal the PCM in a protective shield/cover
assembly.
Vehicles Involved
Involved are certain 1995-96 Chevrolet Cavalier and Pontiac Sunfire (J car) model vehicles built within the VIN breakpoints shown.
Important
Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) prior to beginning campaign repairs. [Not all vehicles
within the above breakpoints may be 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 campaign bulletin. The customer name and
address data furnished will enable dealers to follow-up with customers involved in this campaign. Any dealer not receiving a computer listing with the
campaign 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 campaign.
