Roadworthy woes

[Chanoo]

Hi folks,
Thought I would update you with my new defender and roadworthy issues
I bought a 2002 xtreme last week and subsequently took it in for a roady
All was good except I have the ABS and T/C warning lights on - an automatic fail.
So I needed these to be fixed, took it out to put it on the nanocom and faults logged were L/F sensor and shuttle valve fault

I knew the of sensor was bugged we so asked how much a new one was
The spare parts bloke was really apologetic when he told me it was $488 just for the one sensor, I declined.
Ended up getting a 2nd hand one from a puma for $80 they also told me a disco post 99 would also fit. So half the issue fixed, the nanocom now only logs the shuttle valve fault.
So I'm about to test with multimeter to see if that's stuffed or If i can get away with just fitting a new switch.
I will keep you all posted to the results.

So after a couple of days of reading all about the three amigos and faulty shuttle switches, I think I'm suffering from information overload.
Essentially I have come up with this fix.
I know there is a mountain of info out there, however a thumbs up or down would be great if I'm on the right track.
To fix my issue of the abs light on and after the nanocom has identified a faulty shuttle valve, best to replace the shuttle switch with a new one.
I have checked connections and plugs and earths
Am I doing the right thing, doing what you guys would do
👍🏻. 👎
Thanks
Dave

[emoji107] Option B mod may fix the issue. If you have tested the shuttle valve for the correct resistance values to determine if switches are faulty and get an open circuit reading then Option B. If resistances are ok, then look elsewhere, using The Good Oil as your guide.

When I bought my D2 it had the same shuttle valve faults. I followed the on line tutorials and attached a supplementary earth wire to it.

The job took about 2 hours as I had to remove and refit the ABS assembly, but it only cost about 20cents in parts. 6 years later no further issues.
