I have an Autolink AL619 ( just purchased from amazon) scanner seems to be all up to date, I am able to clear all the OBD codes and also was able to access ABS codes but when I hit erase codes it will not erase this could and the 3 amigos are still there, from what I researched this scanner has got rid of the three amigos code from the abs from other users any idea why it won't clear?? Any advice would be most appreciated.

 

Do you know if the Option B was done on your ABS shuttle valve switch?

 

Good question, I am not aware if it has been done, I have had the Disco for 5 years , not during the time I have owned it , I remember the the 3 amigos were cleared before not by me by a mechanic, so it has been donde before, I don't think it has the B option fix.

​​​​is there a way for me to check if this was fixed visually without removing the modulator?

The three amigos is not something you just clear, you have to actually fix the problem.

 

Check the wiring harness bundle before it plugs into the modulator.

If Option B has been done, you should see the yellow/green wire pulled from the bundle and spliced into another wire that runs under the the modulator to the shuttle valve switches. In the installation pictured, the wire is connected via a two-wire trailer light connector.

You'd also find another wire running from the shuttle valve switches to a ground point. In the pics it also runs through the trailer wire connector. The original Option B instructions showed the ground connected to the A/C line clamp, as shown.
