Okay, wondering if anyone else has experienced anything similar to this.

Driving one night, all 3 ACD lights came on. Shut the car off, checked the fluid, all seemed fine. Fired it back up and it was normal. Didn't do it for a couple more days.

A few days later, driving home at night, the lights came back on. Pulled over to check the fluid, and as soon as I turned the headlights off, the lights went back to normal...

Drove one day with the headlights on, and again, about 20 minutes into it the ACD lights came on. While continuing to drive, shut the headlights off, and boom, back to normal.


So, the jist is the lights only come on after 20 or so minutes of driving, but only when the headlights are on.


I'm not interested in having the dealership pull the car apart looking for some electrical gremlin, so if we can't figure it out on our own, we'll just live with it. I am 99% sure it's not an actual ACD issue, just something with the lights.



Any thoughts, comments, concerns?

could it be a bad ground? loose wires somewhere?
the 20 minutes thing is wierd.

The manual says it'll do that if it's -15 out or something... Is your evo in the North Pole right now?

my 2005 does the same thing, could be because i put a 2004 t-case in there and plugged the banjo bolt though... if you unplug the pump all 3 lights come on. i'd assume something is going wrong with it. my pump is unplugged and i have the same problem.

Electrical Short, somewhere. I bet the dealership will have a ball with your evo. They won't be able to fix it. Just take pictures of the mods and send it in to cancel your warranty. And then blame your mods for causing the problem.

Ok guys, here is the deal, coming from the first car that came with it, Evo7, the thing is, most of the time that all 3 lights comes on, the system needs to be bleed properly, only thing is that the only proper way to do it is by going to the dealer and use the MUTII to be able to raise the correct pressure through the system and properly bleed it. Do not even bother to do it with the engine running, the system will never raise enough pressure.

The manual says if all three lights come on there is likely a problem with your ACD and you should take it to the dealer ... unless it's -13F outside.

We are not taking this to a dealer obviously, its already too late. We've isolated the issue to something electrical - it only occurs when the OEM HID headlights are on.

I would bleed it and see if that fixes it first.

Have a turbo timer by any chance? I notice that the turbo timer does wierd things with the ACD lights, but thats usually when it's active, or the ignition is going off/on. Maybe just FYI.

this has happened to me twice and it really pisses me off when it happens, have no idea why...i shut my car off the one time and turned it back on, the problem was resolved, however like others, i do not want to take it to the dealer.

Did you check to make sure there is no leak coming from the bleeder? Try to have the dealer bleed ACD and see what happen. You are right about not wanting the dealer pull the car apart. Just make sure you tell them to bleed it and nothing more.

could it be as simple as a bad fuse ?

mine has done it before but only when the TT is running and I put the key back to the on position. It has only happend a few times. I wouldn't worry about it untill all 3 lights come on and stay on. That means there is some kind of problem with the ACD according to the owners manual.
