    		 - -

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


      1. Inspect the headlight leveling motor circuit.

        Standard Resistance
        Tester Connection Condition Specified Condition
        B-7 (ACTBI) - P-3 Always Below 1 Ω
        B-8 (ACTSI) - P-2 Always Below 1 Ω
        B-17 (ACTGI) - P-1 Always Below 1 Ω

        If the result is not as specified, replace the headlight unit (headlight cord).

      2. Inspect the low beam headlight circuit.

        Standard Resistance
        Tester Connection Condition Specified Condition
        B-4 (LOLED2) - E-2 Always Below 1 Ω
        B-5 (LOLED1) - E-1 Always Below 1 Ω

        If the result is not as specified, replace the headlight unit (headlight cord).

      3. Inspect the high beam headlight circuit.

        Standard Resistance
        Tester Connection Condition Specified Condition
        C-8 (HILED2) - F-2 Always Below 1 Ω
        C-9 (HILED1) - F-1 Always Below 1 Ω

        If the result is not as specified, replace the headlight unit (headlight cord).

      4. Inspect the headlight fan circuit.

        Standard Resistance
        Tester Connection Condition Specified Condition
        B-6 (FANB) - G-1 Always Below 1 Ω
        B-14 (FANG) - G-2 Always Below 1 Ω
        B-15 (FANP) - G-3 Always Below 1 Ω

        If the result is not as specified, replace the headlight unit (headlight cord).

      5. Inspect the turn signal light circuit.

        Standard Resistance
        Tester Connection Condition Specified Condition
        B-9 (TURN+) - H-1 Always Below 1 Ω
        B-13 (TURN-) - H-2 Always Below 1 Ω

        If the result is not as specified, replace the headlight unit (headlight cord).

  2. INSPECT HEADLIGHT LED UNIT ASSEMBLY

    A0022LXC51
    *a

    Component without harness connected

    (to Headlight LED Unit Assembly)

    1. Apply auxiliary battery voltage to the headlight LED unit assembly and check that the light illuminates.

      OK
      Condition Specified Condition

      Auxiliary battery positive (+) → Terminal 1

      Auxiliary battery negative (-) → Terminal 2

      		 Turn signal light illuminates

      If the result is not as specified, replace the headlight LED unit assembly.
