Citroen C5 2002 ABS sensor lights up after 50 yards

That's the part replaced.
The job went well, fairly easy with some things being slightly awkward. In fact fitting the battery back was the hardest part.

Got amber ABS light constantly now, as soon as I start the engine.
Previously, the amber light took around 50 yards of driving before it came on, so it has made a difference.

If the amber light is now constant right from ignition on, what things could be wrong?

It's a 10 day wait and £50 to get it put on the computer again, so may go for these scan (Lexia) tools.

Before, it was passing all the initial self-tests, then failing when it started to get signals from the wheels.
Now, it's failing the initial self-tests.

I thought as much.

Are any of these scan tools OK for my 2002 C5?

Got a shot of a Lexia - older model.

Started the car first and surprisingly the ABS light was out, drove for 50 yards and amber light came back on - so now the same as it was prior to the ABS/ECU swap.

Connected the Lexia, and got "permanent fault circulation pump",

Now, my question, is this showing the old value and does this need to be "cleared" as I have the option to do that?

I have the car hooked up just now in the drive.
