INTRUSION SENSOR CIRCUIT
CIRCUIT DESCRIPTION
The intrusion sensor (theft warning radar sensor) senses any moving object by using ultrasonic waves and
outputs the signals to inform the theft warning ECU of an intrusion, so that the theft deterrent system can
set off the alarm.
When the theft deterrent system is switched to the arming preparation state, the intrusion sensor is supplied
with S+B by the theft warning ECU. This causes the theft deterrent system to set off the alarm when the signal
is input from the intrusion sensor in a situation such as when the window glass is broken.

(c)Check the indicator.
(1)Turn the ignition switch to the ON position.
(2)Check that the CRUISE MAIN indicator light comeson when the main switch is ON, and that the indica-
tor light goes off when the main switch is OFF.
HINT:
If there is a problem with the indicator, inspect the cruise main
indicator light circuit (See page 05±1722).
(d)Check the DTC.
HINT:
If a malfunction occurs in the vehicle speed sensors or stop
lamp switch assy, etc. during cruise control driving, the ECU ac-
tuates AUTO CANCEL of the cruise control and then the
CRUISE MAIN indicator light will start to blink, informing the
driver of a malfunction. At the same time, data of the malfunc-
tion is stored as a diagnostic trouble code, or DTC.
(e)Output of the DTC using diagnosis check wire. (1)Using SST, connect terminals TC and CG
of DLC3.

(2)Turn the ignition switch to the ON position.
(3)Read the DTC on the CRUISE MAIN indicator light.
HINT:
If the DTC is not output, inspect the cruise main indicator light
circuit (See page 05±1722) and diagnosis circuit (See page
05±1729).
For example, the normal blinking pattern and the blinking pat-
tern for code 52 are shown in the illustration.
