POWER WINDOW CONTROL SYSTEM Front Passenger Side Door-linked Window Control does not Operate

DESCRIPTION

The main body ECU (multiplex network body ECU) detects signals from the courtesy light switch. When the ON signal from the courtesy light switch is sent to the power window regulator switch assembly via the main body ECU (multiplex network body ECU) using LIN communication system, the main body ECU (multiplex network body ECU) will lower the front passenger side door window about 17 mm (0.699 in.) automatically. When the OFF signal from the courtesy light switch is detected, the main body ECU (multiplex network body ECU) will raise the front passenger side door window to the fully-closed position automatically.

CAUTION / NOTICE / HINT

Note

If a power window regulator motor assembly and front door window regulator sub-assembly have been removed and installed, or if a power window regulator motor assembly was reused when a door glass or door glass run was replaced, initialize the power window control system.
