ENGINE FUEL AND EMISSION CONTROL SYSTEM 6C-37
ELECTRIC/ELECTRONIC COMPONENTS
Electronic control unit MS 6.3
The electronic control unit is a "flash EPROM" - i.e. it is
reprogrammable from the exterior without having to intervene on
the hardware. The injection control board has the absolute
pressure sensor integrated to improve the management of the
injection system.
The control unit is fitted on the left side of the engine vane and is
connected to the vehicle via two 43 pole connectors:
- connector A for the components found in the engine
- connector B for the components of the vehicle
