THEFT DETERRENT SYSTEM (w/ Entry and Start System) - Intrusion Sensor Cancel Switch Circuit


DESCRIPTION

  1. When the intrusion sensor cancel switch on the map light is pressed, the sensor off signal is sent to the certification ECU (smart key ECU assembly) which causes the intrusion sensor to stop operating.

INSPECTION PROCEDURE

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

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

    Entry&Start
    Tester Display
    		Measurement Item / Display (Range)
    		Normal Condition
    		Diagnostic Note
    Intrusion sensor OFF
    		Intrusion sensor cancel switch /
    ON or OFF
    		ON: Intrusion sensor active (switch off)
    OFF: Intrusion sensor not active (switch on)
    		-
    OK:
    ON (intrusion sensor active [switch off]) appears on screen.

  1. Disconnect the E30 ECU connector.

  1. Disconnect the R7 light connector.

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    E30-5 (SSW1) - R7-11 (SOFF)
    		Always
    		Below 1 Ω
    E30-5 (SSW1) or R7-11 (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).

  1. 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.


NG
REPLACE CERTIFICATION ECU (SMART KEY ECU ASSEMBLY)
OK

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