    1. Remove the fuses from the instrument panel J/B.
    2. Check the resistance.

      Standard: Below 1 Ω 

    1. NG: REPLACE FUSE 
    2. OK: GO TO NEXT STEP 
  2. INSPECT RELAY (IG1, PWR) 
    1. Remove the relay from the instrument panel J/B.
    2. Check the resistance of the relay.

      Standard: 

      TERMINAL SPECIFIED CONDITION

      Terminal No. Specified Condition
      3 - 5 10 KΩ or higher
      Below 1 Ω
