# CMVSS Noncompliance - Generator Low Voltage Indicator Light PCM Reflash

Subject: | 01029B -- Generator Low Voltage Indicator Light PCM - Reflash

Models: | Certain 2000 Chevrolet Cavalier; Pontiac Sunfire, Grand Am; and Oldsmobile Alero

| Equipped with 2.2L (RPO LN2 - VIN Code 4) or 2.4L (RPO LD9 - VIN Code T) Engine

This bulletin is being revised to add a new calibration part number for the 2.2L (LN2) Chevrolet Cavalier with Compressed Natural Gas option (RPO KL6). This bulletin revision will only be available electronically SI2000. Please discard CMVSS Noncompliance Bulletin Number 01029A, dated June, 2001.

### Condition

General Motors has decided that certain 2000 Chevrolet Cavalier; Pontiac Sunfire, Grand Am; and Oldsmobile Alero model vehicles equipped with 2.2L L4 (RPO LN2 - VIN Code 4) or 2.4L L4 (RPO LD9 - VIN Code T) 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 "Generator Low Voltage" indicator light will not illuminate under low voltage conditions. If the battery voltage drops low enough, the engine will eventually stop running or fail to start.

### Correction

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

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.

Important: Do not attempt to order the calibration number from GMSPO. The calibration numbers are programmed into the vehicle PCM via a Techline tool device.

### Service Procedure

Important: A Techline CD ROM titled "Disc #12" (June 21, 2000) or later software, "Disk #8" for CNG, including the current Techline Information System 2000 (TIS 2000) software, will be required to properly program all vehicles. A Tech 2 will be required to reprogram all vehicles involved.

1. Prep the vehicle for Powertrain Control Module reprogramming.
2. Program the PCM using TIS 2000 data version #12 for 2000 or later; #8 for 2001 or later for CNG. Refer to up-to-date Techline equipment user instructions.
3. Install the GM Campaign Identification Label.

### 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.

### Customer Notification

Customers will be notified of this campaign on their vehicles by General Motors (see copy of customer letter included with this bulletin).

### Dealer Campaign Responsibility

All unsold new vehicles in dealers' possession and subject to this campaign MUST be held and inspected/repaired per the service procedure of this campaign bulletin BEFORE customers take possession of these vehicles.

Dealers are to service all vehicles subject to this campaign at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward.

Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. This could be done by mailing to such customers a copy of the customer letter accompanying this bulletin. Campaign follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.

In summary, whenever a vehicle subject to this campaign enters your vehicle inventory, or is in your dealership for service in the future, please take the steps necessary to be sure the campaign correction has been made before selling or releasing the vehicle.

You may be contacted by a dealer other than the dealer who sold or is currently servicing your vehicle. Please be advised that you may take your vehicle to the General Motors dealership of your choice to have the recall service work completed. Please contact your dealer as soon as possible to arrange a service date.

This letter identifies your vehicle. Presentation of this letter to your dealer will assist their Service personnel in completing the necessary correction to your vehicle in the shortest possible time.
