Circuit/System Description



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.
