DTC B3205, B3210, B3215, or B3220

Diagnostic Instructions

DTC Descriptors

Circuit/System Description

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.

Conditions for Running the DTC

Conditions for Setting the DTC

B3205 00, B3210 00, B3215 00, B3220 00

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

B3205 39, B3210 39, B3215 39, B3220 39

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

B3205 42, B3210 42, B3215 42, B3220 42

The BCM will automatically attempt to download the calibration program into the appropriate 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, B3210 4B, B3215 4B, B3220 4B

The BCM detects that a window motor is "not normalized" which will occur under the following conditions:

Action Taken When the DTC Sets

B3205 00, B3205 39, B3205 42, B3210 00, B3210 39, B3210 42, B3215 39, B3220 39

The affected motor will be inoperative.

B3205 4B, B3210 4B, B3215 4B, B3220 4B

The affected motor will not perform the express up or express down functions and the driver information center will display Open, then Close Driver Window or will display Open, then Close Passenger Window.

Conditions for Clearing the DTC

B3205 00, B3210 00, B3215 00, B3220 00

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

B3205 39, B3210 39, B3215 39, B3220 39

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

B3205 42, B3210 42, B3215 42, B3220 42

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

B3205 4B, B3210 4B, B3215 4B, B3220 4B

The appropriate window motor must be normalized before the DTC can be cleared.

Circuit/System Verification

B3205 00, B3205 39, B3205 42, B3210 00, B3210 39, B3210 42, B3215 00, B3215 39, B3215 42, B3220 00, B3220 39, B3220 42

1. Ignition ON, command the M74 Window Motor UP and DOWN with a scan tool. The M74 Window Motor should perform the UP and DOWN functions.

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

2. Replace the M74 Window Motor with a M74 Window Motor compatible for that specific make and model vehicle.

Circuit/System Testing

B3205 4B, B3210 4B, B3215 4B, B3220 4B

Note:  The 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 while performing the normalization procedure. If this occurs, verify that the door is completely closed then repeat the normalization procedure.

1. Ignition ON, starting with the window completely UP, press and hold the appropriate 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 M74 Window Motor does not perform as specified and the DTC resets, replace the M74 Window Motor.
