Anyone knows if there is anything that has to be done at dealer with MUT III tool after rebuilding the pump (some calibration maybe) ?

I keep taking mine apart and after putting it on the car it works for a while, 1-2 hours, then error returns.

I am close to putting gas on it and just burn it.

You might have to bleed the lines. Air gets in the system when you disconnect the lines to the pump. That's what the MUT III tool is used for.

I was thinking that there are other things the MUT III does besides bleeding.
We did a bleed without MUT, just by gravity after fixing the motor, errors are gone but they reappear when the differentials are supposed to start working (e.g accelerating in tight corners). I will try a bleed at the dealer this week.

Has anyone been able to source a replacement motor for the pump yet? I took mine apart and the motor is toast. Pulled the motor apart and it appears one of the brushes exploded. Anyone know where I can get replacement brushes?

I read a forumer before who rebuilt his acd pump and sent his acd motor to an electrical shop to be reconditioned. Most electrical motors use the same principle so an electrical shop should be able to help you out with that.

Hi,

I know this thread is old, but got a question.

I've been driving my Evo X MR with the AYC/ACD lighst on and always show ACD service requeried, the lights is because of the AYC pump failure? or it could be a selenoid or the pump fuse?

I'm outside the US, so I must be sure if it is the pump failure, because I'll buy one soon.
