No Operation by Interlocked With Key (Only Drivers Door)

POWER WINDOW CANNOT BE OPERATED BY OPERATION INTERLOCKED WITH KEY (ONLY DRIVER'S DOOR)

CIRCUIT DESCRIPTION

When the driver's door is held in the locking state for 2.5 seconds or more via the key operation with no key inserted in the ignition switch, the power window regulator master switch (driver's door ECU) drives the power window motor at the same time when a signal is transmitted multiply to the power window regulator switch (passenger's door ECU) and driver side J/B (body ECU). Then the power window regulator switch (passenger's door ECU) drives the power window motor, and the driver side J/B (body ECU) is transmitted multiply to the rear power window regulator switch LH and RH, then the rear power window regulator switch LH drives the power window motor LH, the rear power window regulator switch RH drives the power window motor RH.

NOTE: Power window system has a function with a large-scale body multiplex communications. First of all, inspect the communication function depending on the "how to proceed with troubleshooting", and check that there is no abnormality in the communication system. Then finally proceed with the troubleshooting. Also, if the power window system has a malfunction in the jam protection function, the AUTO operations are prohibited. Because of this, confirm the diagnostic code is normal before the troubleshooting.
