Starter Inhibitor Relav
16Y3641
Theft-alarm Horn
16Y3003
This relay is located in the relay box at the left front of the engine._.
compartment.
When the system is activated, this relay is activated by the ECU
(transistor Trs).
This relay is usually closed; when it is switched ON, the circuit
jz
conductive to the starteris opened, making starting impossible.
This horn is located at tke right fro~nt oghe eng?ne compaitmen~~
The horn sounds when the horn-relay isswitched ON.
The following components also constitute the theft-alarm sy$em.
Door Switch Left

All doors
Door Lock Actuator Switch

These switches detect the open/close condition of the doors.
(This is a condition for arming the system.)
=_ .i
One of these switches is located at e&h door. They detect-the o%n or
closed condition of the doors, and wh& any one of them FoperGd,
a ground signal is sent tothe ECU. L
When this signal is input while the system is armed. the E~CLJ fur&ions to
activate the alarm.

These switches detect the locked/unlocked condition of the doe% -m
(This is a condition for arming or disamiing the system.)

=_
This switch sends a H6-l signal to theECU when the ign%on keyis mY
at the ON orACC position.
(This is a condition whemrming or disarming the system.)
By inserting the key in the ignition switch, the power to the starter
inhibitor relay is cut, and the engine can be started.
This relay, in the same way as the horn relay, is activated by the&U
(transistorTr2) when the system is activated and the alarm.startS.
When this relay is switched ON, the headlights (upper or lower) are
switched ON.

This relay is activated by the ECU (transistor 7%) when the
system is in its activated state and thepassing control relay :
is closed, thus completing the circuit beginning with fuse No. 1.
