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.

PROCEDURE


  1. READ VALUE USING GTS (INTRUSION SENS OFF SW)


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    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.

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


    1. Disconnect the G79 main body ECU (multiplex network body ECU) connector.

    2. Disconnect the Q16 map light assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      G79-8 (SSW1) - Q16-15 (SOFF) Always Below 1 Ω
      Q16-20 (GND) - Body ground Always Below 1 Ω
      G79-8 (SSW1) - Body ground Always 10 kΩ or higher
      Q16-15 (SOFF) - Body ground Always 10 kΩ or higher
      Result
      Proceed to
      OK
