Technical Engine wiring diagram of x230 2.0 JTD?

[Jorisv]

For my 2002 Fiat Ducato, engine type 230 2.0 JTD, I need the engine wiring diagram.
The ECU in this car is of type Bosch EDC15C7.

In particular I want to know which ECE pin receives the 2nd signal of the acceleration pedal.
It can be different for motor types different from the 230.
Couldn't find it yet in elearn links or elsewhere. Many thanks!

Hi

There is a pinout diagram for the Bosch EDC15C7 on Scribd. Type the link "scribd.com/document/609082605/EDC15C7-Schematic" into your browser(I cannot paste the link directly to this forum)

The six APS (Accelerator Position Sensor) pins are 76 through 81. Be aware that this ECU is used (with different software) for multiple vehicles.

I also have a diagram for the later Fiat X244 model (2002 onwards) which shows the same pin numbers being used for the APS. I have marked the APS and the ECU. The wire colours follow standard Fiat coding.

The APS comprises two potentiometers with 3 connections each, Ground, Supply (5 volts ?) and Output Signal. The ECU compares the two output signals in order to check for malfunction.

I do not have the exact information for your vehicle, so please take this as a guide !

Thank you, Anthony,

This pinout diagram is invaluable!
The voltages as measured near the APS connector are all 6 as expected, when applying the pedal.
Now I can compare this to what comes out from the female connector to the ECU and obtain the resistance of each wire.

The x244 diagram I can use as a guidance indeed; it might be that in the x230 the D004 connector is not one physical part,
but perhaps split up into different smaller connectors, perhaps behind the LH dashboard, as suggested by Communicator.

Thanks again,

Joris
