When a window switch is pressed on the driver window switch, a serial data message is sent to the body control module (BCM). The BCM
examines the request and checks for messages from other power window motors prohibiting the window movement. If no prohibitive messages
have been received, the BCM will send a serial data message to the passenger window motor or to the appropriate rear window switch which will
perform the command as requested.
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, 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
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, B3215 39, B3220 39
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.
