Hi Folks, hope you can help. I have a Jeep Liberty/cherokee 2.8 CRD diesel automatic. 2003. On Friday night my ABS light came on & speedometer stopped working. When I accelerate because jeep speedo isn't working it's not changing gear so reving high. Had a recovery vehicle out & he couldn't get diagnostics unit to connect so couldn't get any codes up. I replaced ABS control module tonight but still same. Any ideas please, thanks in advance, Bill.
