Diagnostic Fault Information

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

Battery voltage must be between 9-16 V.
