CHECK WIRE HARNESS (DOOR CONTROL SWITCH - MAIN BODY ECU (INSTRUMENT PANEL J/B))

POWER DOOR LOCK CONTROL SYSTEM - Door Control Switch Circuit


DESCRIPTION

When the lock side of the door control switch is pressed, continuity is established between terminal 2 (LHD) or 2 (RHD) and terminal 1 (LHD) or 9 (RHD) of the switch. When the unlock side of the switch is pressed, continuity is established between terminal 9 (LHD), 8 (RHD) and 1 (LHD) or 9 (RHD).
Terminals L1 and UL1 of the main body ECU are connected to the door control switch and door lock/unlock request signals (by door control switch operation) are input to the ECU.
The main body ECU constantly applies voltage to terminal 2 (LHD) or 2 (RHD) of the door control switch via terminal L1. When the door control switch is operated to lock all doors, current flows from terminal L1 to terminal 2 (LHD) or 2 (RHD). The main body ECU determines that this is door lock request signal input.
The main body ECU also applies constant voltage to terminal 9 (LHD) or 2 (RHD) of the door control switch via terminal UL1. When the door control switch is operated to unlock the doors, current flows from terminal UL1 to terminal 9 (LHD) or 2 (RHD). The main body ECU determines that this is door unlock request signal input.
