New Procedural Requirements for Powertrain Control Module (PCM) Replacement

Models:

2004-2005 Cadillac CTS, DeVille, Escalade, Escalade ESV, Escalade EXT, SRX, Seville, XLR

2005 Cadillac STS

A new Powertrain Control Module (PCM) return procedure will be implemented beginning April 1, 2004 that will aid us in increasing the accuracy of PCM diagnosis and eliminate unnecessary replacement. Starting at this time, you will be asked to return all CURRENT MODEL YEAR CADILLAC PCMs that are replaced under warranty to the Warranty Parts Center (WPC) along with a copy of the repair order and a completed copy of the form found in this bulletin.

By completing all the information on this form accurately and completely, you will help us to identify and understand the specific diagnostic procedure that led to the replacement of the PCM in order to repair the vehicle. Returned PCMs that are received at the WPC will be functionally tested and, if necessary, installed on a vehicle and driven in order to diagnose the malfunction that led to replacement. We will place particular emphasis on the diagnosis areas you completed on the form so that we can duplicate the condition(s) you encountered as closely as possible. It is imperative that dealerships return the completed form with the returned PCM. Any PCMs returned with incomplete or missing forms AND functionally test as new may be returned to the dealership.

We greatly appreciate your continued cooperation and support on these kind of requests - it essential to improving the quality of the products we supply to you and to our customers.

Important:

•

Normal WPC procedures are outlined in Corporate Bulletin Number 99-00-89-019B, dated January 2002 (dealers in Canada should refer to Home Office Letter 99-201). To increase the effectiveness of this program, submit the warranty claim as soon as possible in order for the WPC to process the necessary return request.

•

ALL CURRENT MODEL YEAR CADILLAC PCMs ARE TO BE RETURNED TO THE WPC. DO NOT RETURN THE PART UNTIL YOU RECEIVE THE REQUEST FROM THE WPC. THE WPC REQUEST WILL BE GENERATED WHEN THE CLAIM IS PAID AND DEALERS SHOULD RECEIVE THE REQUEST ALONG WITH THEIR CREDIT MEMOS. IF A WPC REQUEST IS NOT RECEIVED WHEN THE CLAIM IS PAID, PLEASE CONTACT WPC CUSTOMER ASSISTANCE AT 1-248-371-9901/9902.
