Some customers may comment that the RKE key fob does not function, doors will not unlock from the passengers door switches, or the passenger door window is inoperative. This condition may be intermittent.

Correction

Important
For clarification purposes, the following information is provided. The components involved in this bulletin are known by various names. The Service Information Document ID #849813 refers to the component as the Door Lock and Side Window Switch. General Motors Service Parts refers to the components as SWITCH DR LK & SI WDO. Within this component is a micro processor that is referred to as the Passenger Door Module (PDM). Techline equipment refers to the component as the DMP Passenger Door Module. This bulletin addresses issues with the software of the micro processor in the Passenger Door Module (PDM).


Perform the following procedure step by step (do not skip a step) to determine the proper course of action.

Determine the production date of the vehicle by viewing the certification label on the driver's door.
If the vehicle's month of production is prior to 01/03, GO to Step 2
IF THE VEHICLE'S MONTH OF PRODUCTION IS 01/03 OR NEWER, THIS BULLETIN DOES NOT APPLY.
Use the Tech 2 to determine the PDM operational software release number and system calibration number.
With the Tech 2 installed and powered up, Select F0: Diagnostics.
Select model year: 2003.
Select light truck;
Select F1 body:
Select the proper Product line:
Select Passenger Door Module;
Select F1: Data.
Select F3: and record the "Operational S/W Part Number" here _______________. (If the "Operational S/W Part Number" is not displayed, go to step #4)
Press Exit Once:
Select F4: and record the "Cal Module 1 Part Number" here ________________
Compare the Operational S/W part number and the Cal Module 1 part numbers for the proper repair procedure.
If the Operational S/W part number is 15173756 and the Cal Module 1 part number is 15186199 or 15181562, use normal SPS reprogramming procedures to reprogram the Passenger Door Module (Techline refers to this as the DMP Passenger Door Module) with software from TIS version 2.0, or newer released early February 2003.
If the Operational S/W part number is 15191371 and the Cal Module 1 software is 15186199 or 15181562, use normal SPS reprogramming procedures to reprogram the Passenger Door Module (Techline refers to this as the DMP Passenger Door Module) with software from TIS version 2.0, or newer released early February 2003.
If the Operational S/W part number is 15202869 and the Cal Module 1 software is 15186199 or 15181562, go to step #4 below.
If the Operational S/W part number is 15202869 and the Cal Module 1 software is 15105148 or 15105149, the vehicle has the latest calibration release. Refer to Service Information (SI) for additional diagnostic aids.
Evaluate the vehicle options for proper operation from the PASSENGER DOOR SWITCH ASSEMBLY.
If the passenger door window and door lock function as designed, however the remote keyless entry system is inoperative, use normal SPS reprogramming procedures to reprogram the Passenger Door Module (Techline refers to this as the DMP Passenger Door Module) with software from TIS version 2.0, or newer released early February 2003.
If the passenger door window, door locks and remote keyless entry systems DO NOT function as designed, replacement of the Switch, Dr Lk & SI WDO is required. Refer to the Parts Catalog for the correct part numbers.
After replacing the switch, re-synchronize the RKE key fob. Refer to the Transmitter Synchronization procedure in the Keyless Entry sub-section of the Service Manual (SI Document ID #660745).
