Variation on 3 Amigos

From workshop manual:

...and here's the rest of it:

So with 3 lights showing it could be lots of things?.....sensors checked out ok last time I resistance checked them.....might try them all again.....

Also what's the difference between
HDC fault and HDC info lights?

What do mine indicate

Thanks

Yep pretty much, but the most common cause seems to be an ABS sensor.
Some fault code scanners will tell you which one (mine won't).

I've replaced the front 2 abs sensors at different times, as they went open circuit, but the rear 2 are reading ok?.......I need to make sure there is no rust or dirt on the sensors at the back, but how do I get to them without taking them out, which will mean I will destroy them, as there not coming out without a drill.....Will I need to take the hub off and undo suspension parts to get to the selector ring at the rear......
