3 amigo's questions
I have finally gotten the 3 amigo's, currently working on diagnosing the issue without codes. Yes I know it makes things way harder.
Cause : hard braking on a wet forest service road after replacing the rear left caliper bolts which fell put earlier. Yes I want to punch the guy who did the brakes last in the face.
No issues prior to this. The abs modulator does not appear to working, tested by using hill descent. Although I need to duplicate the test.
No braking issues after bolt replacement.
Rear left sensor cable is plugged in and appears undamaged.
Did the basic resistance test and ohm test for open valves as per these web sites, passed both.

I have not removed the the unit to further test the the valve actuators as yet. But that is on my list for today.
I have a complete spare unit from a 03 which tests electrically fine.
Any suggestions of possible causes, I am arranging to have the codes read but that is a couple of days away.

You could, but even if that clears the codes, option B is WAY less trouble than swappng the entire module. And at some point, the spare module will need the fix as well.

Read the codes! If a wheel sensor isn't working, the ABS modulator won't activate. It's common for sensors to fail at the connections, not the actual sensor head itself. So you could replace all four sensors and still have the issue.
You can get a code reader to do ABS and SRS plus engine codes for around $100 US. It will pay for itself quickly with these D2s.

Richard, my Rover guy, roverbones in Lancaster, PA, fixes I think 95% of these with a sensor bypass on the ABS modulator. I don't have the details of it, but consistent amigos for a year straight led me to him, and he threw that in with something else he was doing and never saw them again.

If you're replying to me, then I have no idea what he does. He doesn't add any unit to the vehicle; I think it's more of a re-routing of wires or something. I can try and find out when I go to him later this summer for refurb'd heads, front cover sealing, head gaskets, valve cover, and harness replacement for the two front O2 sensors which have been drowned by oil (the harness, that is).
