System Description

POWER DOOR LOCK CONTROL SYSTEM DESCRIPTION
1. The power door lock system locks / unlocks all doors.
  - The door control switch of the multiplex network master switch and the driver door key cylinder use the BEAN line to send lock / unlock request signals through the multiplex network master switch to the multiplex network body ECU.
  - The door control switch on the passenger door uses the BEAN line to send lock / unlock request signals through the multiplex network body ECU to the cowl side junction block RH ECU.
  - Upon receiving request signals, the multiplex network body ECU sends these signals to the door ECUs on each door using the BEAN. The door ECUs then lock / unlock each door.
