DTC B3205

The body control module (BCM) monitors, receives and transmits serial data to each of the doors switches and window motors. When a window switch has been activated on the driver window switch, a signal is sent to the BCM which sends a signal to the appropriate window motor and the window motor will move in the direction commanded.

B3205 00

The BCM has detected that the compatibility code stored in the driver window motor does not match the compatibility code stored in the BCM.

B3205 39

An internal malfunction has been detected by the BCM in the driver window motor while commanding the window UP or DOWN.

B3205 42

The BCM will automatically attempt to download the calibration program into the driver window motor (As will occur when the window motor has been replaced), if the first calibration program fails to load, the BCM will attempt to download the calibration program a second time. If this download fails, the BCM will set appropriate DTC.

B3205 4B

The BCM has detected that the driver window is not "normalised" and can set for the following reasons:

The driver power window will malfunction.

B3205 00

Installing a compatible window motor for that specific make and model vehicle.

B3205 39

The driver window motor must be replaced before the DTC can be cleared.

B3205 42

The driver window motor must be replaced before the DTC can be cleared.

B3205 4B

The driver window motor must be normalised before the DTC can be cleared.

B3205 00, B3205 39, B3205 42

1. Ignition ON, command the driver window UP and DOWN with a scan tool. The driver window should perform the UP and DOWN functions.

Note: If the window performs the UP and DOWN functions, clear the DTC

2. Replace the M74D window motor--driver with a M74D window motor--driver compatible for that specific make and model vehicle.

B3205 4B

Note: The all doors must be completely closed prior to normalizing the windows, a door that is open or ajar may cause the power window to function abnormally or it may become inoperative during the normalization procedure. If this occurs, verify that the door is completely closed then repeat the normalisation procedure.

1. Ignition ON, starting with the window completely UP, press and hold the driver power window switch until the window is fully open and continue holding the switch down for approximately 5 seconds after the window is completely open.
2. Pull the power window switch up until the window is fully closed and continue holding the switch up for approximately 5 seconds after the window is completely closed.
3. Command the window to express UP and express DOWN by pressing the window switch past the first detent and releasing and then pulling the window switch past the first detent and releasing. The window should perform the express UP and express DOWN functions.

⇒	If the M74D window motor--driver does not perform as specified and the DTC resets, verify the vehicle doors are closed and repeat the normalisation procedure.

Perform the Diagnostic Repair Verification Diagnostic Repair Verification after completing the diagnostic procedure.
