This is a pretty far reach trying to get help with my abs issue , but here’s the kicker it’s on a Land Rover . I know this is a Hummer forum but The Land Rover Discovery Series II uses the same ABS MODULATOR as the H1 Hummer. The company that manufactures it is WABCO (Meritor WABCO). I’m not fimiliar with abs issues on Hummer like what faults and lights show up but on my car it’s known as the three amigos. The code I’m getting on my car is fault 4012 pump failure 1, high level at x2 pin 8 without pump actuation. On the rover forums no one was fimiliar with this even the people who made the scan tool, is this something anyone has any experience with , like I said I don’t know how much help I can get but seriously no one else was able to help me so I was hoping anyone here could considering atleast the modulator is the same on our cars
