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 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).

      Table 1. 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.

    REPLACE MAIN BODY ECU (INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY)

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

    1. U122574E02

      Disconnect the Q10 light connector.

    2. Disconnect the H80 ECU connector.

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

      Specified Condition

      H80-8 (SSW1) - Q10-10 (SOFF)

      Always

      Below 1 Ω

      H80-8 (SSW1) or Q10-10 (SOFF) - Body ground

    REPAIR OR REPLACE HARNESS OR CONNECTOR

  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.

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

    REPLACE MAIN BODY ECU (INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY)
