EDC16
The EDC.16 control unit offers a few innovations compared to the control unit used with system EDC MS6.3.
- latest-generation hardware and software;
- possibility of processing a greater number of signals (both input and output);
- preset for the control of new additional functions and devices, which will be adopted later for technological improvement
of the product range or compliance with forthcoming anti-pollution rules.
The variants compared with the MS6.3 system are as follows:
- new sensor on the accelerator pedal;
- new sensor on the distributing shaft (phase);
- engine cable;
- bonnet/cab cable;
- new connectors for control unit connection.
The EDC.16 system replaces the MS6.3 system on engines F1A (.10 - .12). It is present on F1C engines.
Diagnosis is only performed by using the diagnostic instruments available. No Blink Code is provided.
The other features are the same as the 6.3 system.
