That fault is a common indication of an ECU fault. Worth checking that the connector to the ABS ECU is not wet or corroded.
Yes it is and i have a broken ecu on my bench that does exactly that. However, when i cleared all faults on my working ecu, left the sensor unplugged and checked for faults again, i got the same error, sensor sorted to another. When i plugged it back in and drove off, the error cleared and the lights went out.
I think because a new sensor dealt with the error briefly, it points to the sensor being duff again, not the ecu dead

Not sure exactly what it is to be honest. It's had 2 sets of sensors in the last couple of months and I logically can't believe both offside sensors have gone wrong. The original fault occurred immediately after doing the front axle balljoints and sensors. The second set was fitted because the garage diagnosed osf short to another sensor and replacing both sensors didn't cure the original fault which is still a short to another sensor. I think the fact that I mentioned to the garage that I had replaced the sensors made them automatically assume that the fault lay with the thing that was last changed. Will a 3rd new sensor fix it ? Who knows ? I spend another £20 speculating on another sensor and then fork out for an abs ecu when the 3rd time lucky speculation fails to cure it. I think it's just bad luck/purely coincidental that the fault occurred after sensor swap.
 
When the garage replaced both, which other one was replaced? Nanocom only says short to another sensor, it doesn't specify which. Can you swap them over to see if the fault moves? It's a shame I'm not closer to you could do some trial and error, i know my ecu is good and know my new sensor is good.
I've proven reliably a good sensor will clear a fault even if it's not fitted, the car doesn't need to move

Hi there,
I renewed both front sensors as I had to destroy the originals to get them out of the hub carriers.
The garage then replaced both front sensors for the 2nd time.
I chucked the first set away as I believed there was no point in keeping them if they were duff.
The nagging suspicion is that there wasn't anything wrong with the 1st set I fitted.
Pity we can't test the ecu itself.

I've read on here that its a short on the LH rear to another sensor that signifies ecu failure, rather than a short on the RH front to another sensor, but who knows for definite ? Marty UK can repair all 4 channels on the abs ecu's for £95 a pop, except that he's still currently out of the country :( I'm also curious that the fault is diagonally opposite to the usual ECU failure error message, so might be ECU related as well.

That gives me an idea.. watch this space.. will try something tomorrow if i get 5 mins

DanClarke had the same issue as me a few years back:-
Nanocom pulls the following message from the ABS ECU "Front Right Sensor short to other" with a count of "12 times".
Have cleared the messages but it immediately reappears on ignition on.
Nothing but trouble this lemon. :(
It was all OK after the replacement of the accumulator and a new Alternator. :)

My Wabco accumulator was new on 07 July, 2020 - dunno about the alternator but it's charging the battery.
Have ordered a Kerr Nelson brand abs sensor tonight, but I intend to remove the battery tray and trace the loom back from the sensor plug to check for a short in the wiring, although I do get +5v dc measured across the male connector pins when the ignition is on.

Incidentally, I seem to recall on some Nanocom pages the WABCO modules get the sensors the wrong way around. I cannot recall if this was fixed in an update. I think Marty posted details somewhere.

Yes i think it was confusing the LH front and LH rear - nothing about the RH side but they fixed the software glitch some time ago.

Have you taken your old abs ecu apart ?
Are there any components that look like they have blown or easily identifiable as being connected to each wheel sensor ? I've got some background in pcb assembly and repair from my time at GEC.
 
Probably been said already but @martyuk can repair certain (not all) faults on WABCO-D units and offers an exchange/repair type of solution where he provides a known good working unit at a price based on you handing over your old failed unit for him to repair and re-sell. Knowing they are becoming harder to source second hand I bought the first one I found for sale on e-bay. One day I will have the courage to test it to make sure it is indeed "Used-Good". :D

Looks like new inside o_O

Trouble is Marty is out of the country again for God knows how long. His oppo is doing the RF receivers but that's all.
 
I guess you would have to trace the sensor connections back from the ecu plug to the individual components on the pcb.
Never seen inside one so I wouldn't know without looking.
Often these sort of problems are due to dry solder joints. I have never seen inside the ABS ECU, but if you have a good magnifying glass and are feeling brave, it might be worth your while opening it up and looking for minute cracks in the soldered joints of components and connector pins.
