Well right before I bought the car the guy worked at a dealership and he changed all the fluids and the clutch was done when the tune was done and he said the lights have been on since the tune which also means when the clutch was done?

this sound to me that maybe the bleeding was done not properly, or the wrong fluidwas used for change/bleed.

Sometimes, also the dealers are not able to do it right. The Mut 3 sucks in that region.
I built my own bleeding tools, so i am not using the stock ACD controller for bleeding.
My tool will replace the ACD-ECU for that during the process.
So i am able to have the pump running during bleed, makes it faster and more Air will be flushed out.
Also changing the fluid is easier then.

I'm new with these systoms so excuse the noob question but if you need to turn the pump on to bleed it can you just put juice directly to the pump? Sure not as easy as a scan tool but cheaper then getting raped at a stealership

problem was fixed.

i put the key to ignition mode and held the throttle pedal. i heard the pump.
then i just assumed its ice in the caliper. so i just kept driving for a while and then went a higher speed in a empty parking lot and slammed on the brakes. the ice melted and the ABS light went off and the ACD lights went back to normal. its been 2 days of driving now and still, all is well.

knock on wood

Its not that easy. the pump ( or call it the fluid pressure ) has to be run and the solenoid has to be activated for bleeding.
BUT, the pump has an pressure sensor, which measures the Pump pressure when running with the ACDECU.
You can overrun the pump/sensor easily when activating with flying wires.

Its possible to do it, but not for an first time user.

german_evoVII

nice to hear, but take care.. if it comes back, start with checking the sensor rings for missing teeth /cracks.
If they are OK, let an dealer or Evo driver with Evoscan read the codes.

This has been happening randomly to me as well.....not sure wtf is going on. Could overfilling the reservoir cause enough pressure for ACD pump failure?

german_evoVII

No, overfilling is not an problem, if it is too much it will be pushed out the cap.

I saw somewhere say you can bleed it if you have someone do the ignition on/throttle down trick...is that true?

Thanks

I had all my lights come on also a few times and it was almost very cold every time, by the next afternoon the light went back to normal

Dose Anyone know how i can bleed the acd pump because i just replaced my clutch and what kind of fluid goes to the acd pump??

Hello all

i just built my EVO for a race car i totally remove evey thing in the car for seam welding the chassis and installing a roll cage now i put everything back, my ACD pump does not work when i start the car and the 3 light are on i tested it by connecting a direct current to it and it was fine.
what do you guys thing is the problem?
do the ABS sensors affect the ACD to not work in idle?
does the ACD ECU has to be in the same place where it was in the stock EVO?
do the G-sensor in the middle behind the gear shiftier has to be installed?
THank you in advance

I have similar issue with my Evo 9 as the OP. When the car idles all is OK. I drive a few 100 feet and all three ACD lights turn on. I ran Evoscan looking for DTCs, but nothing came up. Do I need another program to look for ACD codes? Any help is greatly appreciated.
