THEFT DETERRENT SYSTEM Intrusion Sensor Cancel Switch Circuit

DESCRIPTION

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

PROCEDURE

1. READ VALUE USING INTELLIGENT TESTER (INTRUSION SENSOR CANCEL SWITCH)

   
   

   1. Using the intelligent tester, read the Data List Click here.

      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 pushed OFF: Intrusion sensor cancel switch not pushed	-

      OK
      ON (intrusion sensor cancel switch pushed) and OFF (intrusion sensor cancel switch not pushed) appear on screen according to switch condition.

   
   

   OK

   REPLACE MAIN BODY ECU (INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY)

   NG

2. CHECK HARNESS AND CONNECTOR (MAIN BODY ECU - MAP LIGHT ASSEMBLY)

      *2	Front view of wire harness connector (to Main Body ECU [Instrument Panel Junction Block Assembly])

      Disconnect the Q10 light connector.

   2. Disconnect the H80 ECU connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition H80-8 (SSW1) - Q10-10 (SOFF) Always Below 1 Ω H80-8 (SSW1) or Q10-10 (SOFF) - Body ground Always 10 kΩ or higher

   
   

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR

   OK

3. CHECK MAP LIGHT ASSEMBLY (INTRUSION SENSOR CANCEL SWITCH) (OPERATION)

   
   

   1. Temporarily replace the map light assembly (intrusion sensor cancel switch) with a new or normally functioning one Click here.

   2. Turn the intrusion sensor off by pressing the intrusion sensor cancel switch. Check if the switch operates normally by checking that the theft deterrent system does not operate when you move your hand in front of the sensor.

      OK
      Intrusion sensor cancel switch operates normally.

   
   

   OK

   END (MAP LIGHT ASSEMBLY [INTRUSION SENSOR CANCEL SWITCH] IS FAULTY)

   NG

   REPLACE MAIN BODY ECU (INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY)
