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

DESCRIPTION

The main body ECU (multiplex network body ECU) receives signals from the front door courtesy light switch assembly. When the front door courtesy light switch assembly turns on, a signal is sent to the multiplex network master switch assembly from the main body ECU (multiplex network body ECU) via LIN communication and the driver door power window automatically moves down approximately 12 mm (0.472 in.). When the front door courtesy light switch is turned off, the main body ECU (multiplex network body ECU) sends a signal to automatically move the driver door power window to the fully closed position.

CAUTION / NOTICE / HINT

Note

If a power window regulator motor assembly and 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.
