Electronic Control Unit (Ecu)

The ECU is located on the passenger side, behind the right kick panel. After switching the ignition to "ON", the ECU is connected to battery voltage.

Input signals are received from the coolant temp. sensor, engine RPM, fuel rack position and barometric air pressure. All input signals are processed and used to activate the vacuum converter or switchover valve. An evacuated, sealed capsule is located inside of the ECU sensing pressure differences at varying altitudes.
