Customer Satisfaction 00033 - Battery Rundown - Reprogram RSS Module

General Motors has decided that certain 2000 Cadillac Eldorado ETC model vehicles may exhibit a condition in which the battery runs down within one day because the Road Sensing Suspension (RSS) control module does not shut down when the ignition key is turned off.

Dealers are to reprogram the Road Sensing Suspension (RSS) control module to ensure it shuts down after the ignition is turned off.

Involved are certain 2000 Cadillac Eldorado ETC model vehicles built within these VIN breakpoints:

Important: Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) or GM Access Screen (Canada only) 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.

No parts are required for this campaign.

Important: Updated calibration data required for this service procedure is available on CD #6, released March 31, 2000 (released April 7, 2000 to Canadian dealers).

1. Make sure the battery is at or near a fully charged level ("green eye") before attempting to reprogram the RSS module. Charge the battery if necessary.
2. Depress the parking brake (this will keep the headlamps off during the service procedure).

Important: Do NOT have a battery charger connected to the battery during this reprogramming procedure.

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.
