DESCRIPTION
Front passenger door:
When the ignition switch is ON, the power window regulator master switch assembly sends remote up and down signals to the power window regulator motor assembly (for front passenger door) via LIN communication.
Rear doors:
When the ignition switch is ON, the power window regulator master switch assembly sends remote up and down signals to the rear power window regulator switch assembly (for LH door or RH door). Then, the rear power window regulator switch assembly (for LH door or RH door) drives each power window regulator motor assembly.

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 power window regulator motor assembly (for front passenger door) has been replaced with a new one, initialize the power window control system.
Inspect the fuses for circuits related to this system before performing the following procedure.
As the door control battery is installed between the vehicle battery and main body ECU (multiplex network body ECU), first perform the inspections in On-Vehicle Inspection to confirm that there are no malfunctions in the power source circuit for the main body ECU (multiplex network body ECU) before performing this troubleshooting procedure.*
