Hello, new 2004 Disco 2 owner here. I recently had a seized rear brake caliper. Unsurprisingly, the three amigos popped up soon afterwards plus the red brake indicator light and code p1590. I repaired the seized caliper and the brakes seem to be working normally now, but I still have the three amigos plus the red brake indicator plus code p1590 as soon as I turn on the vehicle. My question is: for those of you who have solved the three amigos, when you solved your issue, did the amigo lights go out, or did you need the special ABS reader tool from rswsolutions to clear the codes? I have a regular OBD scanner, but when I clear the codes, the amigo lights stay on and p1590 reappears as soon as I start the car. I’m unsure if I have a continuing issue or if I just need the $200 scanner to clear the ABS codes. Info: the ABS ECU was replaced by the last owner. Thanks.

 

In my opinion, there is a high probability that the Three Amigos were not triggered by the seized caliper. You'll need a diagnostic tool capable of reading the ABS fault codes to know for certain what to do to address the problem. P1590 always appears when the Three Amigos are triggered but it does nothing to identify the specific problem.

Although it was a good tool when introduced, the RSW Solutions ABS Amigo is no longer the go-to. (In fact, I just now checked the RSW Solutions site and found it is no longer offered. Nor is any other tool offered for the DII.). There are other diagnostic tools touted by others for a little over $100 that do more.

Where are you located? There may be a forum member nearby with a tool that will allow you to get the codes read.

 

I have this. Unbelievable bargain for $99. Mine reads ABS and SRS codes.

I have an ABS amigo, but my three amigos always turns themselves off. I would do the B fix first, its cheap and relatively easy. Plus, if you pull out the plungers and you have oil on them then you know the seals are bad. They are available, if you search you can find them, they ~$40 if I recall correctly. If you do have a leaky shuttle valve, I would pull the ABS pump out altogether to replace the valves, do the B fix and bleed the system. Its not that hard, especially with a jump wire to the relay to run the pump, it practically does it for you.

Its also worth trying to find some lose gravel to fire the ABS system while driving. That may shut off the lights. Or, disconnect the battery to see if that does it.

I have have gotten a consistent or meaningful, or helpful code from my ABS amigo. It seems to always be something different. My amigos comes on very sporadically and there is never a consistent fault.

Or, just dont worry about it, it should not really affect the car.

 

P1590 doesn't usually go away on its own. That's a generic OBDII cover for an error in the ABS subsystem. You need to get hold of a code reader that will show you the ABS error that's underlying it.
