THEFT DETERRENT SYSTEM (w/ Intrusion Sensor) 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 INTELLIGENT TESTER (INTRUSION SENSOR CANCEL SWITCH)

   
   

   1. Connect the intelligent tester to the DLC3.

   2. Turn the power switch on (IG).

   3. Turn the intelligent tester on.

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

      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 intelligent tester switches between ON and OFF in accordance with the intrusion sensor cancel switch status.
