Hi everyone,

I found not much information on the net for ECU Bosch MED17.4. This ecu use for Prince engine earliest model eg Peugeot or Citroen 1.6 turbo 150HP/240Nm torque.

I'm trying to understand the circuitry to solved various issues:-

1. CAN bus comm failure, no communication with diagbox software
2. Random misfiring on all cylinder
3. Oil level gauge fault
4. Coolant temp high.

Anyone has internal circuit diagram, appreciate if could share for a start.

Thanks in advanced :)
