THEFT DETERRENT SYSTEM Intrusion Sensor Cancel Switch Circuit

DESCRIPTION

• When the intrusion sensor cancel switch on the roof console box assembly is pressed, the sensor off signal is sent to the main body ECU (multiplex network body ECU) which causes the intrusion sensor (theft warning ultrasonic sensor) to stop operating.

PROCEDURE

1. READ VALUE USING GTS

   
   

   1. Connect the GTS to the DLC3.

   2. Turn the power switch on (IG).

   3. Turn the GTS on.

   4. Enter the following menus: Body Electrical / Main Body / Data List.

   5. According to the display on the GTS, read the Data List.

      Main Body

      Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
      Intrusion Sens OFF SW	Intrusion sensor cancel switch/ON or OFF	ON: Intrusion sensor cancel switch on OFF: Intrusion sensor cancel switch off	-

      OK
      The indicator on the GTS switches between ON and OFF in accordance with the intrusion sensor cancel switch status.

2. CHECK HARNESS AND CONNECTOR (MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU) - ROOF CONSOLE BOX ASSEMBLY - BODY GROUND)

   
   

   1. Disconnect the H9 main body ECU (multiplex network body ECU) connector.

   2. Disconnect the T10 intrusion sensor (theft warning ultrasonic sensor) (roof console box assembly) connector.

   3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition H9-8 (SSW1) - T10-22 (SOFF) Always Below 1 Ω T10-19 (GND) - Body ground Always Below 1 Ω H9-8 (SSW1) - Body ground Always 10 kΩ or higher

   
   

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR

   OK

3. INSPECT INTRUSION SENSOR CANCEL SWITCH (ROOF CONSOLE BOX ASSEMBLY)
