  1. Remove the map light (LandCruiser RM000003YO9019X.html).

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

    Standard Resistance:
    Tester Connection
    		Switch Condition
    		Specified Condition
    5 (GND3) - 26 (SOFF)
    		Intrusion sensor OFF switch pushed
    		Below 1 Ω
    5 (GND3) - 26 (SOFF)
    		Intrusion sensor OFF switch not pushed
    		10 kΩ or higher


NG
REPLACE MAP LIGHT ASSEMBLY (INTRUSION SENSOR OFF SWITCH) (LandCruiser RM000003YO9019X.html)
OK


3.CHECK HARNESS AND CONNECTOR (MAP LIGHT - MAIN BODY ECU AND BODY GROUND)

  1. Disconnect the W7 light connector.

  1. Disconnect the G64 ECU connector.

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    W7-26 (SOFF) - G64-23 (SSW1)
    		Always
    		Below 1 Ω
    W7-26 (SOFF) or G64-23 (SSW1) - Body ground
    		Always
    		10 kΩ or higher
    W7-5 (GND3) - Body ground
    		Always
    		Below 1 Ω
