Freelander ABS pump failure info.

Had the three amigos appear last week but my dear wife didn't think to tell me and I only discovered them when I was checking car over for it's NCT ( MOT ) .
Had to cancel test as the ABS lamp permanently illuminated is an instant fail.
Took it up to a friends garage this evening to connect his diagnostic system to it to see if there was anything outstanding.
Well I was shocked to be confronted with,
code 001 pump failure (monitor line )
code 002 pump failure 3 (pump sticking )
code 003 shuttle valve switch failure
code004rear left inlet short to ground
code 005rear left outlet valve short to internal supply
code 006rear right outlet valve drive short to supply
code 007rear left outlet valve short to supply.
He tried to reset all fault codes but codes 1,2,and3 remained.
Now call me a bit sceptical but to have all these faults would suggest it had been the victim of a fire flood or earthquake.....
We tested the two front sensors and they came in at 0.97 ohms . The pump could be made to run when hooked up to the diag. system .
The lights come on and go off at random .
I'm awaiting a new brake switch and will check out the HDC switch + wires tomorrow but after doing a search on FL ABS failure there is nothing that mentions the ABS unit specifically failing,all the search results mentioning ABS are associated with the three amigos + brake switch and HDC switch wires.
So is the ABS pump failure a known FL issue or is Poddys diagnostic system a piece of ****e.....

not necessarily so ,its common to get numerous faults show up noting and clearing is the way to narrow down as you have,tester only notes that voltage on a particular circuit wasnt as expected,tis very common to get a list of worrying faults through starts with low battery voltage etc, normally ive found wheel sensors most likely but in your case since pump doe work more likely failure of part that signals pump to work

I currently have this problem, i have replaced the pump and modulator, tried clearing the faults but they won't clear, the pump kicks in when i do an actuator test, but when i read the live data the pump voltage says 0v, anyone have any ideas

pump will only need voltage during specific conditions ie t/c

ok thanks Jamesmartin, any ideas what else the fault could be

We've had 1,000s of earthquakes here in Christchurch over the last 4 years. I've had to change the ABS pump/modulator twice. Both times came up with that Shuttle Valve code.

Both times I've replaced the unit wit 1 from a breakers - which might explain why the first replacement didn't last very long. Current one's been in about 4 months I think, hopefully it'll last a while. You can by the shuttle valve control replacement bits as its a common fault. Depends what year yours is as there's 3 different ABS units of F1. Mine's the early (up to 2000 I believe) WABCO. Then there's a short run on the Teves Mk20 then they shifted to Teves Mk25 - think this info's right.
