THEFT DETERRENT SYSTEM Intrusion Sensor Cancel Switch Circuit

DTC Code DTC Name
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.

CAUTION / NOTICE / HINT

Note:
  • Inspect the fuses for circuits related to this system before performing the following inspection procedure.

  • When replacing the main body ECU (multiplex network body ECU), make sure to replace it with a new one.

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.
