The difference is; I have just noticed that HD TRAC and ABS lights no longer come on at self-test. I have no idea how long this has been going on but the ABS is, at the moment, definitely not working (wheels immediately lock-up when braking hard on gravel driveway).
I have had the beast since last summer and all was well at one point cos I remember having to brake hard months ago in our local High Street and the pedal definitely chattered like a good 'un.
Anyone come across this before or can point me in the right direction re. fuses, relays etc.
By the way, the sls still works fine and I know it shares the same ecu so it might not be a 12v supply problem unless they have separate feeds?
All help gratefully appreciated.

Haven't had this, but you need to hook it up to diagnostics.
 
Thanks for fuse/relay info. I'll check these out before going down the diagnostic route.
There doesn't seem to be anyone local with the diagnostic capability (Blairgowrie, Scotland).
 
Well, I've checked all the fuses and swapped out all the relays but no change. Guess it's a diagnosis now or should I just get a second hand ecu and have it programmed?
