Door Key Lock and Unlock Switch Circuit (Unlock Side)
CIRCUIT DESCRIPTION
The Key–operated switch is built into the door key cylinder. When the key is turned to the lock side, the lock
terminal of the switch is grounded, and when the key is turned to the unlock side the unlock terminal is
grounded.
Furthermore, the door key lock and unlock switch circuit has terminal +B connected inside the theft deterrent
ECU, when neither the lock nor unlock terminal of the key lock and unlock switch are grounded, battery posi-
tive voltage is applied to the door key lock and unlock switch circuit of the wireless door lock ECU.
( Tr inside the ECU coming ON causes the wireless door lock ECU to output a signal to unlock all the doors.)
