I recently had the ABS Module repaired on my 2002 Discovery 2. After doing that I hadn't been able to clear the Three Amigos and twice while driving in rain the truck wheels/brakes locked up while coming to a stop on the slick roads. I have just had the Three Amigos cleared and have been driving it around for the past couple of days and the Amigos have not returned. Should I be concerned about the wheels/brakes locking up? Or just keep driving it until any codes come up...

 

Exactly what procedure was done when you had the ABS module repaired? What ABS fault was being corrected?

 

Boats,
You should go back to the repair shop and make them fix what is wrong since you paid them for it, and as asked already, what exactly did they do and how much were you charged?

 

Three Amigos lit up. I had the shuttle valves and seals replaced on the brake module. The person who helped replace the parts did not have an ABS scanner so I left it as is (Amigos still on) after repairs for several months which is when the brakes did what I had mentioned. I then had another friend with an ABS scanner scan, then erase the Amigos. They still have not come back, but was concerned with the brake issue. I hope that clarifies. Thanks!

 

So, the next time the check engine light comes on with a 1590 fault code number, it will be time to use the 3 amigo scanner again and then get back to us with the exact fault code number.

 

Will do thanks Mike.

 

OK, I had the engine scanned again and these are the codes that activated...
P0306, 88-Brake Light Relay-Open Circuit, 116-Internal Supply, 134-Shuttle Valve Switch. I know that the 0306 is related to the #6 plug. They were changed within the past year. How would I test the plug ( I do not have a timing light)? Any suggestions for the ABS stuff is appreciated. The three amigos is still not on. Thanks!

 

Are you still running the factory grey wires. There can be 3 reasons for the misfire, failing coil, bad wires or bad plug.

 

No they are not stock they are blue.

 

Alright the problem was as simple as replacing the #6 spark plug. Thanks for the advice. Todays project is to dig deeper into the ABS issue. I am gonna run through Atlantic British' test procedure for shuttle valve switches. The downhill descent light has activated a couple of times since my last post.
