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.)

Key Unlock Warning Switch Circuit
CIRCUIT DESCRIPTION
When the key is inserted in the ignition key cylinder, the key unlock warning switch comes ON, and when
the key is not inserted the switch is OFF.
When the key unlock warning switch is ON, the ECU operates the key confinement prevention function.

Door Courtesy Switch Circuit
CIRCUIT DESCRIPTION
The door courtesy switch comes ON when the door is opened and goes OFF when door is closed. Further-
more. the door courtesy switch circuit has terminal +B connected inside the theft deterrent ECU . Battery
positive voltage is applied to terminal DSWD of the theft deterrent ECU when all doors are closed, i.e., when
the door courtesy switches of all doors are OFF.

Panic Circuit
CIRCUIT DESCRIPTION
This circuit will transmit a panic signal from a wireless door lock ECU to a theft deterrent ECU.
When the key is not inserted in the ignition key cylinder and the theft deterrent ECU receives the panic signal
from the wireless door lock ECU, warning operation will be performed.

Indicator Light Circuit
CIRCUIT DESCRIPTION
When the theft deterrent system is preparing to set, this circuit lights up the indicator light. When the system
has been set, it continuously turns the indicator light on for 1 second and turns it off for 1 second, thus blinking
the indicator light.
WIRING DIAGRAM
INSPECTION PROCEDURE
1 Check indicator light.
PREPARATION:
Remove combination meter.
CHECK:
Connect the positive (+) lead from the battery to terminal C9 and the negative (±) lead to terminal B16 of
combination meter connector then check indicator light comes ON.
(See combination meter on page BE±46)
NG Replace combination meter.
OK
