So my D2 is finally showing its true colors at 139k. I recently had to deal with a failed XYZ switch and now the 3 Amigos are popping up intermittently. I have an autocom which has been great for me in the past, allowing me to clear ABS codes for myself and others, most recently to clear a code from a sensor after an inner brake pad went to metal from a frozen caliper. However, it keeps showing me a 115 code whenever I get the lights now which isn't a valid WABCO code. This issue with the autocom has been discussed before but I'm wondering if now that more people have them there has been any conclusion as to what the code means.

The lights seem to come on independent of the brakes so it is probably a continuity issue. I imagine I will be doing an Option B fix in the near future. I'm also wondering if I should plan to do a rebuild with the new shuttle valve seals as well. I bought the truck with 80k on it and the brake fluid had been flushed by the previous owners and I have done it twice since but at this mileage, should I expect it to need the seals too? I'll do the work if necessary but I'd like to be prepared.

 

My 04 had the intermittent amigos last year at 95k. It ended up being the shuttle valve wiring, so I just spliced the shuttle valve switches directly to the wiring harness (I think that's option B).
I don't remember what the code was though.
Good luck.

 

Any luck with figuring this out? I've got the same issue and looking at doing Option B.

 

 

Yep...option B, clear and check.

 

Hice la opción b y el error 115 no desaparece
