All 3 ACD Lights On - Unique ACD problem?!
is your car really low?
do you still have your fender liners?
i had the same issue when i had a snapped ABS wire.
one of the wires caught the tire because i had no fender liners. it snapped the wire under the sheath. BAM! ACD lights come on, and ABS no longer works.
i did a resistance test on the wiring and found one wire that was infinite resistance.. pulled the sheath. soldered the wire back together.. voila. fixed.
good luck

+1 for checking if any ABS wires are disconnected. The reason why the 3 ACD lights don't turn on during idle is because you have not used the brakes yet. You go 200 feet and try to stop and ACD lights come on. Try to perform a hard stop and I bet your brakes will lock. If so, ABS, do what he said ^. Good luck.
I have this issue as well. But it only seems to happen when it is really hot outside. I can almost call whether its going to happen or not based on how hot it is when I walk outside. It also happens sometimes when I run the A/C. I really don't know if its a coincidence with the outside temperature or not but I wasn't having this problem in the Winter. Good Luck fixing your issue.
The very SAME thing has happened to me over the past couple of mornings. I drive between 12 - 13 miles one way to work each morning. The past two mornings the ACD issue has been nonexistant. The temp has been around 75 - 80 degrees and not super humid. However, yesterday leaving work around 3:15PM or so at the height of the heatwave outside, it came on very fast.
How long have you been driving with your issue? I mean, obviously the ACD pump is an expensive fix, is it really necessary to have it fixed? I'd hate to shell out over $1000 for a used ACD pump + install to have 2 lights disappear on the dash
Thanks,

I'll have to keep this in mind too, thanks!

My tires are brand new as of 24 Feb of this year, I highly doubt that is the issue in my case, but thanks for the input. Hopefully that helps others that have the same issue!
Thanks,

I'm pretty sure I'm hearing the ACD pump since the car is not running. The only strange thing is, after the initial test, the pump no longer comes back on and the 3 ACD lights all turn on. I tried the same battery of tests on my brothers 05 Evo GSR and his ACD pump continually comes back on each time I try.
Thanks guys, I'll definitely be checking the see if this an ABS wiring issue or not.
Here's the catch, if it's not then I'm at a loss and have no idea what else to do. The dealership wants $108 just to diagnose the problem, is it worth it for me to do that? I figure if it isn't the ACD pump, then it's worth it since I'll save a crap ton of money. If it IS the ACD pump, then I just paid the dealership to tell me what most of you are telling me LOL....
Any suggestions regarding a next move?
I'll start with:
1) Doing a hard brake to see if it might be ABS wiring related
2) Maybe try to bleed the ACD?
3) Go to the dealership to have them tell me what's wrong
Blah...so IF it is the ACD pump, does anyone know how much labor is to install this beast? I wouldn't be doing it myself, I'm not that car savy....
Any other suggestions for the cheapest way forward are definitely welcomed.
Thanks,
Danny

You can try and bleed the ACD system, but odds are, since you didn't open it etc.... why would it have air in the system? Didn't run the res. down low, its very rare for air to get inside if you didn't touch anything else.
Which than goes back to your ACD pump is probably out.... Ummm the last thing you can do is check the warning lamp codes, by jumping the OBDII port.... there is a thread on it somewhere around here if search for it. Thats what I did for instance... the warning lights will blink in sequence giving you number codes to refer too
Well for starters, if it was an ABS wire issue, you should also have some type of ABS warning light on as well, because it will deactivate that system too. So if you do complete a hard ABS stop ~30-40mph, slam on the brakes it should activate... than its not an ABS sensor issue.

I PM'ed a guy that I found that did an ACD pump install on his evo. he claimed it only took him an hour to do. If anyone else has any input on how hard it is to install an ACD pump I'd definitely be interested.
Also if anyone is selling a low mileage ACD pump I'd be interested in that too!

My ABS is messed up, I had to pull the fuse so the car would brake normal when you first turn it on. The previous owner said Mitsu told him it was a speed sensor but didn't know which one. My Acd lights will not come on driving around town as long as I stay under 50mph. Once I get on the highway and get up to hwy speeds is when all three come on.

Everything on my car is legit, only 25K on the odo. Tires are new, no open circuits.
All I want to know is... What affect will this have on the clutches.
Will power still be distributed 50:50 or will it let the diff run open?
The pump still works, you can hear it run when you depress the pedal with the key in the on position.
