Surge voltage waveform with any charging cable
disconnection.
• May be VHmin = 6.5 V in high electric load shedding
or unloaded condition with the battery fully charged.
(1) Voltage
(2) Angle of Rotation (°)
The ECU will use signal inputs, from the engine
sensors, to control the fuel metering and speed control,
while the engine is operating. As well, the ECU will
provide diagnostic control, over the fuel system.
Ignition timing, fuel rate, and boost levels can be
configured to vary with engine coolant temperature. This
is typically done at very cold or very hot conditions.
Coolant temperature is also used in the airflow models in
the ECU.
