  1. Check the tilt switch resistance.

    Standard resistance:
    Tester Connection
    		Switch Position
    		Specified Condition
    O2-24 (DOWN) - O2-1 (GND)
    		DOWN
    		Below 1 Ω
    O2-25 (UP) - O2-1 (GND)
    		UP
    		Below 1 Ω

  1. Check the tilt & slide switch resistance.

    Standard resistance:
    Tester Connection
    		Switch Condition
    		Specified Condition
    O2-10 (OPN) - O2-1 (GND)
    		OPEN
    		Below 1 Ω
    O2-11 (CLS) - O2-1 (GND)
    		CLOSE
    		Below 1 Ω

4.CHECK WIRE HARNESS (SLIDING ROOF ECU - MAP LIGHT ASSEMBLY)


    B070213E02

  1. Disconnect the M5 sliding roof ECU and O2 map light connectors.

  1. Check the resistance between the wire harness side connectors.

    Standard resistance:
    Tester Connection
    		Specified Condition
    M5-9 (OPN) - O2-10 (OPN)
    		Below 1 Ω
    M5-8 (CLS) - O2-11 (CLS)
    		Below 1 Ω
    M5-4 (DWN) - O2-24 (DOWN)
    		Below 1 Ω
    M5-3 (UP) - O2-25 (UP)
    		Below 1 Ω
