Bosch EDC15C7 ECU

Diesel technology has become less and less popular, but not so long ago, just about all of Europe was driving a diesel-powered car. Driving on diesel was relatively cheap and diesel engines lasted a very long time. Bosch has always been the undisputed number one in the field of diesel ECUs. The Bosch EDC series is therefore well-known. In this article we will take a closer look at the Bosch EDC15C7. How exactly does this diesel ECU work? 

The Bosch EDC15C7 in detail

The Bosch EDC15C7 can be found in various models of Fiat, Alfa Romeo, Peugeot, Citroën, Hyundai and Kia. The ECU is suitable for engines with 4 and 5 cylinders. For example the 1.9 JTD and 2.4 JTD engines of the Fiat group. The letters 'EDC' stand for 'Electronic Diesel Control'. The later 'C' in the type designation stands for 'Common Rail'. This type of ECU is therefore capable of controlling engines that use Common Rail technology: A system in which the fuel is evenly distributed among the injectors via a central supply rail.

The ECU consists of a multi-layer printed circuit board (PCB) containing a large number of SMD components. Apart from the central processor (the CPU) there is also a flash memory, an SRAM memory, an EEPROM and a number of input/outputs (I/O). Nice detail: the injectors are opened by the ECU with a high voltage of 80V, this is designed to make the injector open faster.

Known problems and error codes

The Bosch EDC15 C7 is a well-known ECU at ACtronics. For many problems, we can offer a remanufacture solution. These problems are most common:

  • Car does not start
  • Car cuts out while driving
  • Injectors are not controlled properly
  • Car not running on all cylinders
  • Error codes on injectors
  • Error codes on capacitor voltage
  • No 5V measurable on ECU
  • Tachometer does not work
  • Problems with the immobilizer

Tips before sending the ECU for repair

Many active error codes are usually a result of a defective fuse, a defective relay or a broken wire. So don't think immediately that the ECU is defective, often the cause of the error codes is elsewhere!

Disassembling the ECU

Removing the ECU is not very complicated.

  • Disconnect the battery terminals
  • Remove the plugs from the ECU
  • Unscrew the bolts
  • Remove the ECU from the car

Mounting the ECU is usually not too difficult either:

  • Mount the ECU in the car with the corresponding bolts
  • Place the plugs on the ECU
  • Attach the battery terminals.
