Technical 2005 2.8 jtd abs/asr fault

[apee]

Hello all. The ABS & ASR lights on my motorhome recently came on & the Multiecuscan program located the fault to the right rear speed sensor which I then replaced. After a test drive the lights had gone out but after driving a longer distance the lights came on again but go out each time I restart the engine. I scanned it again & the program says there is an intermittent fault; the right rear speed sensor value is too high & the front left load solenoid value is too low. Any ideas what the solution is please?

Hi,, see my post here-

https://www.fiatforum.com/ducato/447611-abs-light-brake-failure-more-thoughts-all.html

amd other related posts for this and no connecting with ABS unit with multiecuscan. I ended up at Fiats and got it fixed, was told it was a bad earth, but the guy who did the job did not come out and see me before I had to get going. I believe it may have been an issue in one of the connector blocks that plugs in to ABS unit- dirty, corroded usual fiat guff that they are very prone to I should think. Still ok for now tho. I also believe that those 2 lights denote a fault with the front/rery electronic brake force distributor valve. My vehicle is a 3 axle motorgome BYW, also 2.8JTD X244, yr2005.

Check connector fir water ingress, check the spade connector that plugs into. The bottom of the engine bay fusebox for corrosion.
