POWER DOOR LOCK CONTROL SYSTEM All Doors LOCK/UNLOCK Functions do not Operate Via Door Control Switch

DESCRIPTION

• for LHD:

  Operating the power window regulator switch assembly (door control switch) sends a manual door lock/unlock request signal via direct line to the front multiplex network door ECU RH, and afterwards the manual door lock/unlock request signal is sent via CAN communication to the main body ECU (multiplex network body ECU).

  After the main body ECU (multiplex network body ECU) receives the door lock/unlock request signal, it operates the door lock/unlock motors to lock/unlock each door.

• for RHD:

  Operating the power window regulator switch assembly (door control switch) sends a manual door lock/unlock request signal via direct line to the front multiplex network door ECU LH, and afterwards the manual door lock/unlock request signal is sent via CAN communication to the main body ECU (multiplex network body ECU).

  After the main body ECU (multiplex network body ECU) receives the door lock/unlock request signal, it operates the door lock/unlock motors to lock/unlock each door.
