INSPECTION PROCEDURE

CHECK VEHICLE TYPE

CHECK BASIC FUNCTION (ENTRY AND START SYSTEM)

INSPECT FUSE (ECU-IG1, AM1, AM2-2)

CHECK WIRE HARNESS (THEFT WARNING ECU - IG POWER SOURCE AND BODY GROUND)

THEFT DETERRENT SYSTEM - Ignition Switch Circuit


DESCRIPTION

When the ignition switch is on (IG), the battery positive voltage is applied to terminal IG of the theft warning ECU. When the battery positive voltage is applied to terminal IG of the ECU while the theft deterrent system is operating, the warning siren stops. Furthermore, the power supplied from terminal IG of the ECU is used as the power for the door courtesy light switch and position switch, etc.
