Circuit Description

The window switch or signal circuit that failed and generated this diagnostic trouble code (DTC) is wired to one of the passenger door modules. Each passenger door window switch is supplied voltage, via an up signal circuit, and voltage, via a down signal circuit, by the associated passenger door module. The passenger door window switch ground circuit is also supplied by the associated passenger door module. When the window switch is operated, the normally open contacts of the signal circuit are closed to ground. Voltage flows from the door module, through the signal circuit, switch contacts, and ground circuit, to provide the door module with a signal input. The passenger door module shares this switch signal input information with the driver door module (DDM), via the power door serial data circuit. When a passenger door window switch circuit is closed to ground for too long, the DDM is informed and sets the appropriate DTC.

Conditions for Running the DTC
    • The passenger door module associated with the failed switch or circuit must be powered and can not have DTCs B1327-Battery Voltage Low or B1328-Battery Voltage High set.
    • The DDM must be powered and cannot have DTCs B1327 Battery Voltage Low or B1328-Battery Voltage High set.

Conditions for Setting the DTC

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

Action Taken When the DTC Sets

The action taken depends on which circuit is closed:

    • If the UP circuit of the passenger door window switch is closed for more than 15 seconds, the associated window will not move UP or DOWN when operated from the passenger door switch until the UP circuit is no longer closed, or, the power mode changes from OFF to RUN.
    • If the DOWN circuit of the passenger door window switch is closed for more than 15 seconds, the associated window will not move DOWN when operated from the passenger door switch until the DOWN circuit is no longer closed, or, the power mode changes from OFF to RUN. UP movements are still permitted regardless of the DOWN circuit state.

In either case, the affected window will operate normally from the driver door switch assembly (DDSA).

Conditions for Clearing the DTC

The DDM clears this current DTC when the failed circuit message is no longer received. 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 verifys that the input is seen by the module.

    3.

  3. This step verifys that the signal lines to the module are open with the switch removed.

    4.

  4. This step verifys that the signal circuits are not shorted.

  1. Activate the appropriate passenger door window switch.
  2. With the scan tool, observe the Door Window Switch parameter for the appropriate passenger door.

Does the Door Window Switch parameter change from Idle to Up and Down?

Go to Testing for Electrical Intermittents in Wiring Systems

Go to Step 4

4
  1. Turn OFF the ignition.
  2. Disconnect the appropriate 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 appropriate passenger door.

Does the scan tool display Idle?
