INSPECTION PROCEDURE

PROCEDURE


  1. INSPECT POWER SWITCH

    A01GW6BE02

    1. Disconnect the L36 power switch connector.

    2. Apply battery voltage between the terminals of the power switch, and check the illumination condition of the power switch indicator light.

      Note


      • If the positive (+) lead and the negative (-) lead are incorrectly connected, the power switch indicator light will not illuminate.

      • If the voltage is too low, the indicator light will not illuminate.

      OK
      Tester Connection Condition Specified Condition
      Battery terminal (+) → Terminal 11 (SWIL) - Battery terminal (-) → Terminal 5 (GND) Always Illuminates
      Battery terminal (+) → Terminal 12 (INDS) - Battery terminal (-) → Terminal 5 (GND) Always Illuminates
      Battery terminal (+) → Terminal 13 (INDW) - Battery terminal (-) → Terminal 5 (GND) Always Illuminates
