THEFT DETERRENT SYSTEM Intrusion Sensor Cancel Switch Circuit

DESCRIPTION

• When the intrusion sensor cancel switch on the map light assembly is pressed, the sensor off signal is sent to the main body ECU (multiplex network body ECU) which causes the intrusion sensor to stop operating.

INSPECTION PROCEDURE

PROCEDURE

1. READ VALUE USING GTS (INTRUSION SENSOR CANCEL SWITCH)

   
   

   1. Connect the GTS to the DLC3.

   2. Turn the power switch on (IG).

   3. Turn the GTS on.

   4. Select the item below in the Data List and read the display on the GTS.

      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) - MAP LIGHT ASSEMBLY)

   
   

   1. Disconnect the L8 main body ECU (multiplex network body ECU) connector.

   2. Disconnect the U3 map light assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition L8-8 (SSW1) - U3-7 (SOFF) Always Below 1 Ω U3-1 (GND1) - Body ground Always Below 1 Ω L8-8 (SSW1) - Body ground Always 10 kΩ or higher
