COMPONENT DESCRIPTIONS
Injection control unit (EDC-15C Common Rail)
It is fitted to the right side of the engine bay. The control unit is the 'flash EPROM' type, i.e. reprogrammable from the outside without intervening on the hardware.
The injection control unit integrates the absolute pressure sensor.
