  1. Remove the personal light.

  1. Measure the resistance of the connector.

    Standard resistance:
    Tester Connection
    		Switch Condition
    		Specified Condition
    13 (UP) - 8 (B)
    		TILT UP
    		Below 1 Ω
    13 (UP) - 8 (B)
    		Off
    		10 kΩ or higher
    29 (DOWN) - 8 (B)
    		TILT DOWN
    		Below 1 Ω
    29 (DOWN) - 8 (B)
    		Off
    		10 kΩ or higher
    12 (OPN) - 8 (B)
    		SLIDE OPEN
    		Below 1 Ω
    12 (OPN) - 8 (B)
    		Off
    		10 kΩ or higher
    28 (CLS) - 8 (B)
    		SLIDE CLOSE
    		Below 1 Ω
    28 (CLS) - 8 (B)
    		Off
    		10 kΩ or higher

4.CHECK WIRE HARNESS (PERSONAL LIGHT ASSEMBLY - DRIVE GEAR AND BODY GROUND)
B107181E02

  1. Disconnect the Y6 and Y7 light connectors.

  1. Disconnect the Y10 drive gear connector.

  1. Measure the resistance of the wire harness side connectors.

    Standard resistance:
    Tester Connection
    		Specified Condition
    Y6-13 (UP) - Y10-3 (UP)
    		Below 1 Ω
    Y6-29 (DOWN) - Y10-4 (DWN)
    		Below 1 Ω
    Y6-12 (OPN) - Y10-9 (OPN)
    		Below 1 Ω
    Y6-28 (CLS) - Y10-8 (CLS)
    		Below 1 Ω
    Y7-8 (B) - Body ground
    		Below 1 Ω
