I got a bit interested in this when I was immobile. The P38 is a complex beast but I couldn't get to grips with the idea that everything was custom made for it.
I stumbled upon the 'stomp' test for the BMW EDC (This one will do http://forums.bimmerforums.com/forum/showthread.php?p=24001364) . I didn't get it to work but I am now wondering whether RR disabled it to keep the mystery.
I've got an annoying intermittent ABS fault that I think is a loose sensor. Browsing today I cam across this www.[B]meritorwabco[/B].com/MeritorWABCO_document/mm38.pdf
It seems that Wabco has a blink system as well. (Sorry about the italics - they won't go away). What interested me is that it is activated by a switch. Now, if there was a ABS diagnostics switch fitted to the P38, I am sure that it would have cropped up in loads of threads. I haven't found one.
Here we need an auto electrician. If you go back to the document link, open it and find figure 2.2, the switch seems to just be a jumper across two of the ECU pin-outs. TBH, I'm a bit Becks up to work out which ones. I'll have a closer look another time.
Anyway, has anybody invested any time in exploring the built-in blink codes that Wabco and Bosch seem to have used?
I quite expect more experienced posters to refer me to thread xxxxand point out that I'm talking rubbish.
