- INSPECT POWER SWITCH
- Check the resistance.
- Measure the resistance according to the value(s) in the table below.
*a Component without harness connected
(Power Switch)Standard Resistance
Tester Connection Condition Specified Condition Result 12 (SS1) - 3 (GND) Not pushed 10 kΩ or higher kΩ 6 (SS2) - 3 (GND) Not pushed 10 kΩ or higher kΩ 11 (SS3) - 3 (GND) Not pushed 10 kΩ or higher kΩ 12 (SS1) - 3 (GND) Pushed Below 1 Ω Ω 6 (SS2) - 3 (GND) Pushed Below 1 Ω Ω 11 (SS3) - 3 (GND) Pushed Below 1 Ω Ω If the result is not as specified, replace the power switch.
- Measure the resistance according to the value(s) in the table below.
- Check the LED illumination.
- Apply auxiliary battery voltage between the terminals of the power switch and check the illumination condition of the power switch indicator light.
*a Component without harness connected
(Power Switch)OK
Condition Specified Condition Auxiliary battery positive (+) → Terminal 5 (SWIL)
Auxiliary battery negative (-) → Terminal 3 (GND)Illuminates If the result is not as specified, replace the power switch.
- Apply auxiliary battery voltage between the terminals of the power switch and check the illumination condition of the power switch indicator light.
- Check the resistance.
