The plug for the sensors is ok and the others "look" ok, hardly a test i know.
I think I’m going to send the ECU off to be 100% sure.....anyone know a cheep ECU tester?

Look OK may not be good enough, just a trace of green corrosion between pins can play havoc.
 
I think i have asked everyone now. They have all said ABS ECU change. I wonder what the chances the ECU sent to me was dodgy - its the only explination.

Not heard of a lot going wrong on here. Might just be unlucky.
 
I will let you know how it goes. I requested an unopened box. ECU testers on the IoW and an indy auto electrician said swap it...........I need my luck to change on this.
 
Well, after an ECU and a fuse box replacement (it didn't smell great), another full loom test, then the inspection of the NSR/RL half shaft, I can say the problem has gone away. It was the half shaft..........

I replaced the half shaft (second-hand £30) as the original abs ring had slight scores on it!!

Moral of the story - check you half shaft rings through the sensor hole!!

Glad to hear you've got it sorted

Strange that Hawkeye showed you a good signal, and yet it was a damaged reluctor ring

No wonder it took some getting to the bottom of
 
It showed wheel speed and voltage, but as you might know - Hawkeye doesn't show them all together so you can compare.....

Only when on another snap-on system could a comparison be drawn, RL was showing a lower voltage/wheel speed, but not by much. I can confirm the system is extremely sensitive!!!

I really hope this helps someone else one day.

Yup! Helped me today!

I have been right through my ABS, (and most of the Landy-web) to try and solve my ABS problen and this is the only thing left. As I had a seriously dodgy front N/S bearing I think it has goosed my ring, if you'll pardon the expression!

I haven't got Hawkeye, so no I didn't know. But worth bearing in mind.
 
I tested voltage output from WABCO D ECU to front sensor joints today ( inside inner- guards) .... both read: 5.02v .... Tried continuity test... Would I be right in saying if sensors are good...reading should be '000' - ie: reading at sensor pins ?

Answered that in a PM. Voltage is good obviously no circuit through sensor. :);)
 
Cheers Wammers..... Hopefully new sensors will arrive over here by mid-week ... as MOT test booked for next Saturday .....

Im not sure what you are testing V8HSE, are you testing each loom wire for ohms?

If you disconnect the loom wires with ignition on you should see 5 volts in loom. You then need a circuit through the sensor. If you are getting 5 volts at the loom but no circuit through the sensor it won't work. The sensors are magnetic as the reluctor ring passes the sensor nose it varies the magnetic field effecting the voltage. This change in voltage is detected by the ECU and treated as a pulse. 8000 pulses per mile. As long as your tyres and wheels are the correct size that is. :D:D:D
 
Sounds right to me, dont forget to check the ABS ring for imperfections, as I found out, the slightest thing can upset it!!!!!!
