I forgot I still have my Delphi DS150 also but barely use it.
Yep. Windows computer only and it comes with the Delphi program for all makes and models of cars and SUVs and the OBDII connectors for the different cars. There is a another Delphi program for commercial vehicles too.

 

I also have a Delphi 150. It caused me a headache and a lot of extra work a year ago when I got the Amigos. The DS150 showed codes for the right rear sensor - erratic and no output. I found a dead mouse laying on that sensor, so it made sense.
I replaced the sensor with one that ran all the way to the SLABS ecu. Problem solved for a few days, then the codes returned. I double checked my work, and all seemed good. I figured I had a defective sensor (got it from Rockauto). Returned it and got one from RoversNorth. (A short one this time, and returned the wiring back to original). Again problem solved for a few days.
I finally used the graphing features of the software to watch the sensors in real time, and found the left front sensor dropping out!
So, while the left front sensor was the issue, the DS150 was erroneously reporting a code for right rear.
Replaced the left front sensor, and the Amigos were vanquished.

 

I’ve read on another forum or Land Rover blog that even the Nanocom reads sensors backwards like this.
The Nanocom will show a fault for the right front sensor but it’s actually the left rear if you turned the Disco around.
It works something like that but it’s still weird.

 

Well that's interesting.

I used the Delphi software to diagnose the Three Amigos on my truck. It said right rear sensor. I battled it for months and months. The Amigos were clear for a few weeks, but then came back again. But by that time I'd picked up an ABS Amigo for only a few bucks. I decided to buy it because using it is easier and faster than hooking up the Delpi, plus I can easily do it on the fly. It says the new fault is left front sensor. I was at least happy it wasn't the right rear. I've cleared the codes and for now they haven't come back, but when they do (and they surely will) I'll diagnose with both the ABS Amigo and the Delphi and see if the codes are the same or different. And report back, of course.

 

I guess a way to test that theory is to quick disconnect the ABS sensor on one side and see which sensor shows up for the fault on your fault reader.
