Reading Ford ABS Data

This way you can make sure the software can connect to the ABS module in your vehicle before purchasing anything else.

Thanks for the reply. I've downloaded the software but i'm not able to connect to the ABS.

I've opened the software, entered my car details, selected Ford ABS from the Diagnostic System drop down then clicked connect. It successfully connects but it only seems to connect to the Generic OBD-II and doesn't say anything about the ABS system.

Could you provide me with some step by step instructions?

Many thanks

Hi,

Is there any chance you can talk me through how to do this?

Cheers!

If you select the ABS system in the drop-down and hit connect and it works, then you are definitely talking to the ABS module. Often times the ABS module uses the same protocol as the generic OBD-II stuff, so you are able to get data from both systems simultaneously in our software.

You can now go to the Settings tab and then PID Config to see what parameters are supported by your vehicle. You will still need a license key to actually do anything besides view Engine RPM.

Hi cobrajet,
please, could you say me what systems are in Ford (Focus, Mondeo) ?
I thinked that there are/were systems with connection on K-line, or not ?
All ABS are on SCP/CAN bus ?
Thanks very much in advance.

Tomas

Ok i've just tried this now. I'm connecting but not getting anything else...not even the RPM monitor!

When I look in the logs I get: Failed to initialize OBD-II data logger! Error 703: Error: parameter list is empty.

Any ideas?

It sounds like your ABS system and the OBD-II system are on different protocols. So you won't be able to do any Engine RPM data logging (which is the only PID available without a license) while connected to the ABS system. Since all the ABS PIDs require a license key to work, the logging engine filters them out automatically, which is why the parameter list is empy. If you want to unlock the full functionality you would need to get a license key. Did you know that mp3car.com sells ScanXL with the Ford Enhanced Add-on?

Setup hyperterminal then set the headers to talk to the ABS module. Here is what I did to talk to the ABS module on a CAN Ford:

>atz
ELM327 v1.3 compatible
>ath1
OK
>atsh760
OK
>220200
768 04 62 02 00 00
>1800ff00
768 02 58 00
>223987
768 07 62 39 87 00 00 00 00
>22e200
768 06 62 E2 00 1B 0F 68

mode $22 PID $3987 gives the individual wheel speeds. Above 00 00 00 00 because vehicle was stopped.

mode $22 PID $E200 gives software rev

Look at the ELM327 datasheet for details on commands. To setup hyperterminal, a good reference is http://www.glmsoftware.com/TipsAndTricks.aspx

i finally got abs readings to work in my ford ranger 1999 xlt.

scanXL with ford addon, it took a little bit of playing around, but now its easy to work. i was immediately able to tell that my rear differential sensor is faulty, and that is why my abs light has been on for 2 years. tomorrow i will replace it and see if that works!

i just recently finally took care of my engine light too... i started by replacing all 3 o2 sensors, which helped, then i cleaned a bunch of other ones.. and by the time i replaced the pcv valve i was finally able to keep that light off. my truck is about to turn 200k!
