INSPECTION PROCEDURE

1.READ VALUE USING INTELLIGENT TESTER

  1. Connect the intelligent tester to the DLC3.

  1. Turn the power switch on (IG).

  1. Turn the intelligent tester on.

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

    Main Body (Main Body ECU (Multiplex Network Body ECU)) 
    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.

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

  1. Disconnect the H17 main body ECU (multiplex network body ECU) connector.

  1. Disconnect the T6 map light assembly connector.

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    H17-23 (SSW1) - T6-26 (SOFF)
    		Always
    		Below 1 Ω
    T6-3 (GND3) - Body ground
    		Always
    		Below 1 Ω
    H17-23 (SSW1) - Body ground
    		Always
    		10 kΩ or higher

3.INSPECT INTRUSION SENSOR CANCEL SWITCH (MAP LIGHT ASSEMBLY)


    B270925E04

  1. Remove the intrusion sensor cancel switch (map light assembly) (Click here).

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    26 (SOFF) - 3 (GND3)
    		Intrusion sensor cancel switch not pressed
    		10 kΩ or higher
    26 (SOFF) - 3 (GND3)
    		Intrusion sensor cancel switch pressed
    		Below 1 Ω
