Sniffing 2000’s Ford

Projects Networking, Protocols, and Devices

Hi,

I have a 2004 Ford Focus 2.0 with EEC-V 60 pin ECU.

The OBD2 connector pinout is as follows:
1, 3, 6, 8, 9, 11, 12, 13, 15 - Blank

The populated pins are: 2, 4, 5, 7, 10, 14, 16

Which is pretty similar to the picture bellow:

I imagine this car uses J1850.

I´ve tried to sniff something using M2 and Savvycan but I couldn´t have any results.
Turns out that M2 doesnt support the PWM protocol yet, so I'm looking for alternatives.

The idea is to sniff Fords J1850 PWM protocol to hook up a standalone ECU and make everything work just like the OEMs.

So I need a device that could gather CAN bus values from the standalone ECU and broadcast J1850 PWM.

Some one could help me out?

Thanks!

Are you aware of the raw data you're expecting to receive over OBD2? You are correct ford in the 00 range used j1850 PWM @100kbs

Google "MCP2515" (it should come with an MCP2551 as well) they are used to transmit and recieve.

You'll need a lookup table of some type to translate whats recieved into something reasonable. I have a 2000 expedition 5.4 and a Snap-On modus scanner, so if you need any protocol info I may be able to pull it using that Snap-On scanner
