Started getting the three Amigos with greater frequency. I bought an ABS Amigo which read the following codes:114:Shuttle Valve Electric Failure (current fault) and these:022:ECU Gnd or Reference Gnd bad (previous faults 1) and finally these:022:ECU Gnd or Reference Gnd bad
064:Front Right sensor electric fail
065:Rear Left sensor electric fail
066:Front Left sensor electric fail
067:Rear Right sensor electric fail (previous fault 2)
All that being said, given the number of times the amigos have appeared, I would have thought there were more faults. Also, if I shut the vehicle off, 90% they do not reappear for a while?
Any thoughts from the duty experts?

 

How many miles on your truck, when did you last do a full 2 quart DOT4 brake flush?
Start by reading Josh's write up on the ground and shuttle valve replacements. Do both repairs and clear your codes, see which of the other codes comes back.
If you have any questions, send me your number and I'll call you.

 

"winston" has 66k on the clock. The brake flush is on my list as is the transmission. I cleared the codes with this amigo read and I was thinking that I would start with the flush before I got into Joshs' repair. What are your thoughts? I am reasonably handy and have backup if get in over my head

 

At your mileage, you had better look at my major service list for a guide.
As for the flush, you are past the point of having the flush help you, your ABS module is leaking internally and that needs to be done first.

 

I have been working your list slowly, trying to find the time is difficult. Just so I understand you completely, when you say ABS internal leak, do you mean that fluid is getting past the shuttle valves?

 

"YUP"!
Any more question, send me your number so I can call you.

 

Many Thanks. I see the Falcon works kit Josh is taking about, and his stick. I will be intouch when I can get this underway. Thanks Mike.

 

Just a note: The seals in the shuttle valve don't have to be leaking for the shuttle valve switch to fail. When I dove into my Amigos, my shuttle valve switch tested bad, but it was dry as a bone. I replaced the seals with the FalconWorks kit, and did the ground repair as per Josh's writeup, since I knew both were potential problems that would appear at some point in time, and since I was already right there.
