my 3 lights are on also...

 

Lol that sucks. Maybe your harness is bad?

 

All 3 lights came on in my IX RS. Luckily I'm covered for another year under warranty, let's see what the dealer says, I'm going to try and bring it in today.

 

Bleeder valve was loose, simply tightened and it solved the problem. I had been leaking ACD fluid for a few weeks now, just never noticed.

Here's what I've learned, this may already be obvious to others.


(1) While the car is running the ACD fluid will actually go below the min line, this tends to freak some people out but is totally normal.

(2) Once you turn the car off, it takes 90 minutes at least for the ACD fluid to get back to the max line. Again, this freaks people out who check the level before 90 minutes are up.

(3) Use only Mitsubishi Diamond ATF SP3 fluid in the ACD reservoir. It's relatively cheap, around $6.50 a quart from the dealer, it's a thin red fluid.

(4) You can actually run the ACD pump without turning on the car. You turn the key to the last position before you can crank the car, then press the accelerator pedal, and you should hear the ACD pump running.

(5) Three ACD lights at the same time can mean multiple things, including but not limited to: (a) ACD fluid low (b) ACD pump failing (c) brake sensor (d) certain fuse shorts (e) air in ACD system





Edit: if your Mitsubishi dealer does not carry ATF SP3, check Hyundai or Kia, they use the exact same thing.
