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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      6 (+S) - 3 (E) Heater switch assembly off 10 kΩ or higher
      Heater switch assembly on Below 1 Ω

    2. Apply battery voltage to the connector and check the LED illumination.

      OK
      Measurement Condition Specified Condition

      Battery positive (+) → Terminal 5 (ILL+)

      Battery negative (-) → Terminal 4 (ILL-)

      		 LED illuminates
