Ford Fiesta 2002-…

Below the steering wheel, there is a small flap; behind it, the diagnostic connector is hidden.
At least pins 6 and 14 are connected, so I assume the vehicle has at least a diagnostic CAN bus.

If anyone could tell me how to find out for sure, please let me know.

Furthermore, I believe that the car has something similar to an in-car CAN bus system, because the radio also seems to be connected to it.
I haven't checked there yet (it's a bit more complicated).

Best regards,
Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

Hello,

You can either measure the voltage at the two pins in the OBD2 connector to see if there is power present (indicating a CAN bus that is active, which sometimes happens with Ford vehicles even when the engine is "off").

Best regards, Rainer.

Ouch, I could have thought of that too...

I'll try it out as soon as I find a multimeter.
Unfortunately, all of the devices are at home .

The question comes late, but:
Does anyone have a list of part numbers for Ford vehicles?

We apologize for the German text; please use a translator: ( .
My Ford Fiesta MK6.5 (2002 - 2008) and I want to implement an onboard computer that connects via the CAN bus. While many things can be accessed through the OBD2 protocol, the data regarding fuel consumption and the climate control system is not displayed using the standard PIDs (0x10 and 0x5E).
I tried to observe and capture the CAN-HS bus traffic to obtain the desired data. In the documentation, I found a detailed description of the content of messages, but some of this information conflicts with the fact that when I 'capture' it, the bytes for ID 0x420 are always 0x01h, 0x02h, or 0x04h.
Perhaps there are differences in the description of the content of these bytes for newer Ford models, but I couldn't find any information online about where exactly the fuel level data is stored.
If the fuel consumption is not displayed on the dashboard, it only appears in cars before refueling. However, you can see this information in diagnostic mode.
Here are some pictures taken during the last trip, with message ID 0x430:
2E 00 01 5A 01 00 69 29
5C 42 00 02 01 00 24 5B
B7 63 02 63 01 00 22 4A
0C 81 02 96 01 00 46 20
AE 87 04 00 00 27 9E 8E
The fuel consumption, as measured by the OBD2 Bluetooth adapter and Torque software on the mobile phone, averaged between 5 and 10 liters per 100 kilometers.

I have a Ford Fiesta MK6.5 (2002-2008) and I want to create an onboard computer that is connected via the CAN bus. While the OBD2 protocol allows access to much data, here I need information about fuel and air consumption. The car does not display this information using the standard PIDs (0x10 and 0x5E).
I tried to monitor the communication on the CAN-HS bus and capture the desired data. In the subject (http://www.canhack.de/en/viewtopic.php?t=792)), I found a detailed description of the contents of the messages, and some of this information matches what I'm seeing, but here, in ID 0x420, byte 3, I consistently see 0x01h, 0x02h, or 0x04h.
'It's possible that the way the contents of these bytes are described varies for newer Ford models, but I couldn't find any information online about precisely where the fuel consumption data is stored.'
'The fuel consumption isn't displayed on the dashboard; it only shows the mileage since the last refueling. However, I can view this value in diagnostic mode.'
Here are some captured messages with ID 0x430 from the most recent trip:
2E 00 01 5A 01 00 69 29
5C 42 00 02 01 00 24 5B
B7 63 02 63 01 00 22 4A

AE 87 04 9E 00 00 27 8E
Average fuel consumption (obtained through the OBD2-Bluetooth adapter + Torque software on the mobile phone) is between 5-10 liters per 100 kilometers.
