  1. Remove the engine switch (RAV4_ACA30 RM0000020P000NX.html).

  1. Apply battery voltage to the switch and check the illumination condition of the engine switch indicator light.

    OK:
    Measurement Condition
    		Condition
    		Specified Condition
    Battery terminal (+) → Terminal 11 (SWIL)
    Battery terminal (-) → Terminal 4 (COM) or 5 (GND)
    		Battery voltage is applied to the terminals
    		Illuminates
    (Illumination of lettering)
    Battery terminal (+) → Terminal 12 (INDS)
    Battery terminal (-) → Terminal 4 (COM) or 5 (GND)
    		Battery voltage is applied to the terminals
    		Illuminates (green)
    Battery terminal (+) → Terminal 13 (INDW)
    Battery terminal (-) → Terminal 4 (COM) or 5 (GND)
    		Battery voltage is applied to the terminals
    		Illuminates (amber)
    NOTICE:
    1. If the positive (+) lead and the negative (-) lead are incorrectly connected, the engine switch indicator light does not illuminate.
    2. If the voltage is too low, the indicator light does not illuminate.
