CMVSS Noncompliance - Oil Pressure Light PCM - Reflash

General Motors has decided that certain 2000 Chevrolet Monte Carlo model vehicles equipped with 3.8L V6 (RPO L36 - VIN Code K) engine fail to conform to Canada Motor Vehicle Safety Standard (CMVSS) 101, "Location and Identification of Controls and Displays." These vehicles may exhibit a condition in which the "Oil Warning Light" will not illuminate under low/no oil pressure conditions. If the engine is operated with insufficient oil pressure, engine failure could result.

Dealers are to reflash the vehicle PCM with new calibration software.

Important: Vehicles previously repaired under warranty have been excluded from this campaign.

Involved are certain 2000 Chevrolet Monte Carlo model vehicles equipped with 3.8L V6 engine (RPO L36 - VIN Code K) and built within these VIN breakpoints:

Important: Dealers should confirm vehicle eligibility through GM Access Screen (Canada only) before 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.

A new flash program has been released to address the above-mentioned condition. The calibrations for the carlines and year affected by this campaign are included and available from GM Service Operations beginning with the TIS 2000 #6 CD-ROM release of March, 2000. The following tracking table shows the individual carline calibration update number.

Important: A Techline CD ROM, titled "Disc #6" (March, 2000), or later software, will be required to properly program all vehicles. A Tech 2 will be required to reprogram all vehicles involved. Also, refer to the Techline Customer Support Center help line.

1. Prep the vehicle for Powertrain Control Module reprogramming.
2. Program the PCM using TIS 2000 data version #6 for 2000 or later. Refer to up-to-dateTechline equipment user instructions.
3. Install the GM Campaign Identification Label.

Place a Campaign Identification Label on each vehicle in accordance with the instructions outlined in this Product Campaign Bulletin. Each label provides a space to include the campaign number and the five (5) digit dealer code of the dealer performing the campaign service. This information may be inserted with a typewriter or a ball point pen.

Put the Campaign Identification Label on a clean and dry surface of the radiator core support in an area that will be visible to people servicing the vehicle. Additional Campaign Identification Labels for Canadian dealers can be obtained from DGN by calling 1-800-668-5539 (Monday-Friday, 8:00 am to 5:00 pm EST). Ask for Item Number GMP 91 when ordering.
