THEFT DETERRENT SYSTEM Intrusion Sensor Cancel Switch Circuit

DESCRIPTION

When the intrusion sensor cancel switch on the map light sub-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.

If the main body ECU (multiplex network body ECU) is replaced, refer to the Service Bulletin.

PROCEDURE


  1. READ VALUE USING GTS (Intrusion Sens OFF SW)


    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.


      Body Electrical > Main Body > Data List
      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

  2. CHECK HARNESS AND CONNECTOR (MAP LIGHT SUB-ASSEMBLY - MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU) AND BODY GROUND)


    1. Disconnect the G17 main body ECU (multiplex network body ECU) connector.

    2. Disconnect the N9 map light sub-assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      G17-3 (SSW1) - N9-27 (SOFF) Always Below 1 Ω
      N7-22 (GND) - Body ground Always Below 1 Ω
      G17-3 (SSW1) or N9-27 (SOFF) - Other terminals and body ground Always 10 kΩ or higher
      Result
      Proceed to
      OK
