Connector Voltage
(Main Circuit)
1. Turn on the main switch. (Do not start engine.)
2. Measure the voltage between terminal 31 (+) and terminal 7 (–).
3. It is OK if the voltage equals to the battery voltage.
(Sensor Voltage)
1. Turn on the main switch. (Do not start engine.)
2. Measure the voltage between terminal 34 (+) and terminal 33 (–).
3. It is OK if the voltage is approx. 5 V.
