ABS MODULATOR FIX (NO more SVS fault)
#251
I restarted the truck, drove and the amigos come on, but no p1590 rough road code, which is strange, because I believe that is immediately thrown off if the ABS ECU finds a fault.
So, I got my amigo out, and tested the system. It showed no active faults, but a logged fault. So that got me thinking that possibly the logged fault stayed there, and is causing the amigos. It sort of defies logic, because I think that the ABS AMigo clears the codes logged or otherwise, but maybe, just maybe a logged fault had stayed in the system.
I cleared the codes a few times so it showed no active or logged faults.
Went on a test drive and the amigos did not come back on during the 20 minute test drive, but sometimes it takes longer, sometimes not.
We'll see if I get lucky.

Thank you for your contribution to the community, it is a great asset for a lot of us. I performed this fix using the tutorial but once I saw the general idea I got lazy and just sort of dived in. It amazes me how much misinformation is floating around in various threads so to clarify for anyone who happens to stumble up this post since I'm sure it's been touched upon in the hundreds of other responses, YOU ARE NOT BYPASSING A SAFETY MECHANISM AND IT PERFORMS THE SAME FUNCTION AS IT WOULD OR SHOULD BE FROM THE FACTORY
for some reason, people seem to think that this is bypassing the entire abs system. It is basically just replacing a bad connection between two parts with a good one
I used a 2x4 block to support the unit and it took about an hour, would probably be able to do it in half that now knowing what it entails
Super easy, no bleeding brakes. My soldering iron wouldn't make enough heat to combat the cold weather here so I used some crimp caps. I also didn't use the trailer connector but regular 16 gauge wire I had laying around. So while soldering would be preferable, the resistance with crimping showed no difference if you are feeling lazy like me

My amigos were turning on, but not staying on. I noticed on my scangauge that the 1590 was there, so I thought maybe not clearing that was doing something, so I cleared that code.
