Circuit Description

The switch that failed and generated this diagnostic trouble code (DTC) is one of the window switches built into the driver door switch assembly (DDSA). There are no external circuits. The DDSA contains a microprocessor which takes the signals generated by these switches and their contacts and assigns them a digital message. The DDSA sends the message, via the power door serial data circuit, to the driver door module (DDM).

Conditions for Running the DTC

The DDM must be powered and must not have DTCs B1327-Battery Low Voltage or B1328-Battery High Voltage set for this DTC to set.

Conditions for Setting the DTC

If the driver door module (DDM) receives the message that the contacts for a DDSA window switch are closed for more than 15 continuous seconds, the DDM sets this DTC.

Action Taken When the DTC Sets

The action taken depends on which contacts are closed:

    • If the UP contacts of the switch are closed for more than 15 seconds, the associated window will not move Up or Down when operated from the DDSA.
    • If the DOWN contacts of the switch are closed for more than 15 seconds, the associated window will not move Down when operated from the DDSA. UP movement from the DDSA is still permitted.
    • If the Express Down contacts of the switch are closed for more than 15 seconds, the Express Down function is disabled, but Up and Down window functions are not affected.

During any of the actions taken, all passenger doors will still operate from their respective passenger door window switch.

Conditions for Clearing the DTC

The DDM clears this current DTC when the failed switch signal is no longer received. The DTC is stored as a history DTC. The history DTC will clear either after 50 OFF/ON cycles of the ignition switch 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.

Did you perform the Door Systems Diagnostic System Check?

Go to Step 2

Go to Diagnostic System Check - Door Systems

2
  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
  3. With a scan tool, observe the Driver Window Switch parameter for the appropriate window switch in the driver door module (DDM) Inputs list.

Does the scan tool display Idle?

Go to Step 3

Go to Step 4

3
  1. Activate the appropriate driver door window switch.
  2. With the scan tool, observe the driver door window switch parameter for the appropriate switch.

Does the door window switch parameter change state?

Go to Testing for Electrical Intermittents in Wiring Systems

Go to Step 4

4

Inspect for poor connections at the driver door window switch harness connector. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 6

Go to Step 5

5

Replace the driver door switch assembly. Refer to Front Door Switch Replacement .

Did you complete the replacement?
