WIRING DIAGRAM
CAUTION / NOTICE / HINT
Note
The power window control system uses the LIN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the power window control system after confirming that the communication system is functioning properly.
If the front door window regulator assembly (for passenger door) has been replaced with a new one, initialize the power window control system.
Tech Tips
If the pulse sensor built into the front door window regulator assembly (for passenger door) is malfunctioning, the power window control system enters fail-safe mode. The remote up and down and auto up and down functions cannot be operated during fail-safe mode. However, the power window can be closed by holding the power window regulator switch assembly at the auto up position, and opened manually by pushing down the power window regulator switch assembly.
