*a Component without harness connected
(Engine Switch)Standard Resistance
Tester Connection Condition Specified Condition 5 (SS1) - 6 (AGND)
1 (SS2) - 6 (AGND)Not pushed 10 kΩ or higher Pushed Below 1 Ω If the result is not as specified, replace the engine switch.
- Measure the resistance according to the value(s) in the table below.
- Check the LED illumination.
- Apply battery voltage between the terminals of the engine switch and check the illumination condition of the engine switch indicator light.
OK
Condition Specified Condition Battery positive (+) → Terminal 9 (SWIL)
Battery negative (-) → Terminal 6 (AGND)Illuminates HINT:
- If the positive (+) lead and the negative (-) lead are incorrectly connected, the engine switch indicator light will not illuminate.
- If the voltage is too low, the engine switch indicator light will not illuminate.
If the result is not as specified, replace the engine switch.
