Have you driven over 5mph? Pretty sure the fault message can't be cleared any other way. Only the codes can be cleared
I have been for a drive at 20mph+ for a few minutes and it still happens the same as before unfortunately.

The message comes via the BECM so check the BECM connectors for corrosion.I've had the dash out already and everything seemed ok
The reason I had the dash out was because when I bought it I had a weird feeling that an "ABS fault" message should be accompanied with an ABS light, and at the time, it wasn't... Lo and behold, someone had taken the bulb out.

Are you getting a audible tone aswell as the lights
It could be a wheel sensor then, the first check is the system the second check is for sensor feedback if I'm correct?
You can with the nanocom read the speed sensors behavior upto 5 or 8mph and see how they respond. Over that speed the nano can't track them.A Nanocom showed no faults, and also that all four sensors appeared to have valid voltage readings. (2.31 from memory) so I initially thought the sensors were ok.
How can you diagnose which sensor(s) are at fault?

As the OP's "fault" message appears before any motion of the vehicle (so no waveform pulses/frequencies to compare yet) and all the sensors were showing 2.29/2.3V on my Nanocom when we looked and when a sensor fails you get 0v shown then it rather suggests to me that the ECU should be swapped out as a next step or put the vehicle up on axle-stands and let it idle away in gear at a few MPH while you check live data/speeds from each wheel?
Very puzzling then. If there are "no faults logged" and the message pops up on start-up where's it coming from?Aha I didn't know that, it would be useful to see the values reported to confirm the wheel sensor states.
Agreed - unless a sensor is outright dead, I don't see how the ECU could determine that it was faulty without the vehicle moving.
I have swapped a 'tested and working' ABS ECU in, exactly the same part number as mine, but it does not make any difference. Behavior is identical
My thoughts exactly.Very puzzling then. If there are "no faults logged" and the message pops up on start-up where's it coming from?
I wonder if your ABS pump hi/low pressure sensors are duff?
Nope, never seen that message before. What would that indicate?Do you get the 35mph max message on the dash?
Sorry, was thinking about the eas relay, but that's for.. er.. the easNope, never seen that message before. What would that indicate?
