Circuit Description

The switch that failed and generated this diagnostic trouble code (DTC) is wired to one of the passenger door modules. These modules contain a microprocessor which takes the signal generated by this switch and assigns a digital message to the switch signal. The door module then sends this message over the power door serial data link to the driver door module (DDM).

DTC Descriptors

This diagnostic procedure supports the following DTCs:

    • DTC B3172 RF Window Up Switch Circuit Low
    • DTC B3177 RF Window Down Switch Circuit Low
    • DTC B3182 LR Window Up Switch Circuit Low
    • DTC B3187 LR Window Down Switch Circuit Low
    • DTC B3192 RR Window Up Switch Circuit Low
    • DTC B3197 RR Window Down Switch Circuit Low

Conditions for Running the DTC

The DDM and the passenger door modules all must both be powered and cannot have B1327 Battery Voltage Low or B1328 Battery Voltage High set for one of these DTCs to set. If one of the DTCs indicating a loss of communications with a door module is set, the setting of DTCs from that module is prohibited.

Conditions for Setting the DTC

If the DDM receives a message indicating that a window switch is closed for more than 15 continuous seconds from a passenger door module, the DDM sets the DTC.

Action Taken When the DTC Sets

The action taken depends on which switch is closed:

    • If an UP switch is closed for more than 15 seconds, both UP and DOWN movement is prohibited until the UP switch is no longer closed, or, the power mode changes from OFF to RUN.
    • If a DOWN switch is closed for more than 15 seconds, the DOWN movement is prohibited until the DOWN switch is no longer closed, or, the power mode changes from OFF to RUN. UP movements are permitted regardless of the DOWN switch state.

Conditions for Clearing the DTC

The DDM clears this current DTC when the switch message is not received, or when the module power mode changes from OFF to RUN, and stores the DTC as history. The history DTC will clear either after 50 OFF/ON ignition switch cycles without a repeated failure, or in response to a scan tool command.

Test Description

The numbers below refer to the step numbers on the diagnostic table.

  1. This step checks the module input state using the normal input status.

    2.

  2. This step checks to see that the input is seen by the module.

    3.

  3. This step checks to see that the signal circuits to the module are open with the switch removed.

    4.

  4. This step checks to see that the signal circuits are not shorted.

  1. Turn OFF the ignition.
  2. Disconnect the inoperative passenger door window switch.
  3. Turn ON the ignition, with the engine OFF.
  4. With a scan tool, observe the Door Window Switch parameter for the inoperative passenger door.

Does the scan tool display Idle?
