Active value: Starter switch has to be turned “ON”NOTE:
Measuring points between component and wire harness have to be connected. Passive value: Starter switch has to be turned “OFF”
Measuring points between component and wire harness have to be disconnected.
Measuring points are engine controller’s points and passive value is each component’s value.
V_batt: Source power of equipment.
