For symptom byte information, refer to Symptom Byte List Symptom Byte List.

Circuit/System Description

The body control module (BCM) monitors, receives and transmits serial data messages to the driver and passenger 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

* The ignition switch is in the ON position.

* Battery voltage must be between 9-16 V.

Conditions for Setting the DTC

B3205 00, B3210 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

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

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

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

* When the battery has been disconnected

* When the battery has been replaced

* When the door wiring harness has been disconnected

* When the window motor has been disconnected.

Action Taken When the DTC Sets

B3205 00, B3205 39, B3205 42, B3210 00, B3210 39, B3210 42

The affected motor will be inoperative.

B3205 4B, B3210 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

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

B3205 39, B3210 39

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

B3205 42, B3210 42

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

B3205 4B, B3210 4B
