    NG: REPAIR OR REPLACE HARNESS AND CONNECTOR 

    OK: Go to next step 

  3. INSPECT FUSE (DOME, D/C CUT) 
    1. Remove the DOME fuse and D/C CUT fuse from the engine room No. 1 relay block.
    2. Measure the resistance of the fuses.

      Standard resistance: 

      Below 1 Ω 

    NG: REPLACE FUSE 

    OK: Go to next step 

  4. CHECK WIRE HARNESS (MAP LIGHT ASSEMBLY - BATTERY) 
    1. Disconnect the W6 map light assembly connector.
    2. Measure the voltage of the wire harness side connector.

      Standard voltage
