DTC B3542
CIRCUIT DESCRIPTION
The driver door module (DDM) and passenger door module (PDM) check for hall sensor pulses of their respective window motors at least once every 50 milliseconds. When the DDM or PDM detects no hall sensor pulses in the window motor, a DTC is set. For more detailed information concerning power window operation refer to Power Windows Description and Operation.

DIAGNOSTIC AIDS
The following conditions may cause an intermittent malfunction:
- There is an intermittent sticking or binding condition on a window causing the window to be unable to move.
- A window motor is shorted internally.
- Thoroughly inspect the wiring and connectors. An incomplete inspection of the wiring and connectors may result in misdiagnosis causing part replacement with the reappearance of the malfunction. If an intermittent malfunction exists, refer to Diagnostic Aids for Circuit Testing and Wiring Repair Procedures. Component Tests and General Diagnostics
