Customer Satisfaction - Remote Keyless Entry (RKE) System Inoperative

On some 2003 model year Cadillac Escalade, Escalade EXT, and Escalade ESV; Chevrolet Silverado, Avalanche, Tahoe, and Suburban; GMC Sierra, Yukon, and Yukon XL; and HUMMER H2 vehicles, the passenger door module (PDM) may become inoperative. An inoperative PDM would cause loss of function for the remote keyless entry, front passenger power window, lock, mirror and heated seat functions.

Dealers are to reprogram the PDM.

Involved are certain 2003 model year Cadillac Escalade, Escalade EXT, and Escalade ESV; Chevrolet Silverado, Avalanche, Tahoe, and Suburban; GMC Sierra, Yukon, and Yukon XL; and HUMMER H2 vehicles built within these VIN breakpoints:

Important: Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) or GM Access Screen (Canada only) or DCS Screen 445 (IPC only) prior to beginning program 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 program bulletin. The customer name and address data furnished will enable dealers to follow up with customers involved in this program. Any dealer not receiving a computer listing with the program 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 program.

No parts are required for this recall.

Important: The labor time for performing the refresh/reprogram of the passenger door module in this recall is different than the amount of time allowed in Service Bulletin 03-08-52-001B. The labor operation code and time allowance in the service bulletin was for a BCM reprogram, and was not the correct labor operation code for this repair.

Inspection Procedure

Important: The following inspection must be performed in order to determine the correct repair procedure.

1. Turn the ignition to the ON position.
2. Using the switches in the right front passenger door, verify that the power window and power door lock located in that door, function properly.

•	If the power window and door locks do NOT function, proceed to the "Refresh and Reprogram" procedure and follow ALL of the steps.

•	If the power window and door lock function properly, the vehicle only needs to be updated with the new calibration for the passenger door module. Proceed to and follow only steps 4-6 in the "Refresh and Reprogram" procedure. DO NOT PERFORM STEPS 1-3.

Refresh and Reprogram Procedure

Important: Steps 1-3 in the following procedure should only be performed if the power window and door lock did NOT function properly in the inspection procedure above.

Important: In order to perform the following procedure, your Tech 2 must be updated with software version 23.001 or later, CD #3. If your Tech 2 does not have the necessary software, it will need to be updated before proceeding.

1. Turn the ignition switch to the ON position.
2. Connect the Tech 2 to the vehicle's diagnostic link connector (DLC), power it up and press enter.

4. Follow normal Service Programming System (SPS) to reprogram the passenger door module with the new calibration.
5. After reprogramming is complete, using the switches in the right front passenger door, verify that the power window and power door lock located in that door, function properly.
