where is the bleed nipple for the acd? pictures would be helpful. thanks

 

ok i just test drove my EVO 8 and i follow the steps form this thread and it fixed the problem, thank you so much for the advice. earlier in the afternoon i drove the car my all 3 of my ACD indicator lit up. I tried resetting the battery but it didnt work. I tried starting the car with my foot on the gas peddle it rev up to about 5000rpms but it did not work. so after doing some research and understanding how the ACD system works. here is what fixed my problem. I turn the key to the ON position without starting the ignition meaning without starting the engine, with my foot all the way down on the gas peddle. then i started hearing the ACD pump doing its work. i first inspected the ACD reservoir and it was on the FULL line. after turning the key to the on position without starting the engine. the ACD started pumping the fluids for about 30secs. I inspected the ACD reservoir again and it was now down to the MIN line. after that I test drove the car for a few miles. so far its been on a steady Tarmac indicator. I hope this helps most of you guys. its a good way to find out if you ACD pump is working. if my all 3 of my ACD indicator lights come on again, then I know it might not be the ACD pump. I emailed a freelance Mistubishi Mechanic who specializes in EVO's he emailed me with a reply of

"hey man,

I'm just relying on what you e-mailed me, if you said that you drained the acd fluid and you replaced it with a new one, just make sure you top it off when the engine is on idle mode
so that the pump will push the fluid all the way in the system it will take some time to fully
get rid of the air bubbles that was stuck inside the acd and make sure you fill it up all the way to its marking spot. but if you are still having problems with all the selector lights being lit all together when your driving it, you may have to replaced your ACD unit ,where this kind of setup is controlled by a electronic hydraulic multi-plate clutch (thats your acd unit formely known as your transfer case) meaning the plates(made of metal) inside your acd/transfer case is slipping already and by the time you give the car a bit of a slight pull
all lights are coming out because of the slippage and when you come to a stop it will only lit one which is tarmac coz every single gear is at rest, all your sensors are ok but it seems to me that you are having a ACD/TRANSFER CASE problem thats in need of replacement. the more you drive it, the more loosing its 50/50 balance (just like the SUBARU sti's they have that knob for balancing the 4wd system distribution) eventually your transmission...my advise to you is act on it right away i know its costly but you have to save your ride.." I HOPE some of this info helps. I'll keep everyone posted. maybe tomorrow i will inspect my abs wheel sensors.

 

Hi guys, I have one problem with my 05 EVO GSR, during the winter season ACD works well, but during summer seson when its very hot, i have 3 acd lights. when it raining it works well, only when hot it didnt work. whats the problem is? can bleeding help? I have 3 " dp instled, meybe its to hot for acd?

 

Im having that exact same problem. all 3 ACD lights come on during hot weather. when its night time the 3 lights go away. i checked the pump and is working fine. to test or bleed ACD pump. keep foot on accel and turn the key ON without starting engine. keep foot on accel for about 5 sec you should hear the ACD pump working.

i took it to Midas for a Diagnostic check and it ran up a code 32 g-sensor and also DTC P0830: Clutch Pedal Position Switch Circuit Range/Perfor. if you have warrenty on the car, it should be covered by mitsubishi. im taking it there on monday

 

hi yes, problme is same, the pump ids working. bleeding didnt help...its going on my nervs, car hasnt warranty, couse its USDM, I am from Europe

 

had mitsubishi bleed my acd but that didnt correct the problem.my guess is that g-sensor is having problem during hot or high humidity weathers because that is the only time the 3 lights come on. i'll drive the car during the day when is hot and it comes on. then later at night when is cool the lights dont show up. when i turn on the AC during hot days, the lights dont come on. the g-sensor is underneath the center console by the handbrake. there are 2 sensor chips. one is lateral and one is longitudinal. imma try to see if mitsubishi will warrenty the sensors.

 

Pretty much an LSD for the SRT4 04+

 

good info hoser...keep it up

 

great info

 

Thanks for doing the write-up. Its great!

 

nice write up.

 

Hey Guys, I got a question.. So I got my ACD just replaced and when the car runs all 3 lights are on.. Gonna try bleeding, but other than that when I switch the car onto ON (not running) all the gauge lights turn on and my 3 ACD lights light up, then just one ACD light is on and to the Selected mode and I can change the mode within a few seconds before all 3 ACD lights turn on again. Is this normal?

EDIT* Well I know all the 3 lights going off isn't normal but if I could get any ideas, suggestions?

 

so i have read alot of this and i cant find the answer i need...My light for the acd isnt working...WTF??? i think i may have put a fuse in the wrong spot when fing around but i might be wrong..were is the ACD fuse??

 

Hey Terry, sorry to rattle your cage but:

I've been trying to nail down some ACD operating basics and it seems your thread is considered to be the word. You state that Tarmac/Gravel/Snow settings progressively keep the diff locked later after initial turn-in, and that each has progressively less locking force. You cited source 7 and 12 for that info. I couldn't find that info on those links. It's likely the sites have changed over the years since you wrote this.

But today I was talking to Robert at Robispec and he's sure the three modes give progressively MORE locking force, not less. Actually this doesn't seem logical to me since the slipperier the surface, you'd think you'd need less locking to perform the same function. But anyway, that's what he said, and he has the rep.

And my X has a bar-graph on the dash that shows ACD locking, and I see no evidence that gravel or snow modes actually carry lock into a turn. I get high locking as I brake approaching a turn, but as soon as I turn-in with or without trail braking, the bar-graph goes to zero -- regardless of ACD mode.

Bottom line, I still don't think I know how TGS works. There's an excellent Mitsubishi Motors technical review on the S-AWC but it doesn't cover ACD in detail. And I found this:

http://www.mitsubishi-motors.com/cor...001/13E_09.pdf , but it doesn't even reference Tarmac-Gravel-Snow.

So...anyone have any detailed info on ACD modes from the Mitsubishi tech people? I'm not sure we should trust anyone else. Too many opinions out there presented as fact.

 

FWIW, I had the ACD pump replaced under warranty (I know, hate on me) and the relay blew when the fired it up.

Take this with a grain of salt, but the dealership ordered a new relay which was on backorder and has a new part number (I dont have either the old or new part number yet as I have one more, unrelated, warranty replacement item that has to be completed prior to them providing an invoice with part numbers for me) and I was informed that the older relay was a constant problem and they replaced it frequently.

Once the relay was replaced, then the 60a fuse blew.

End result is that the Pump, relay and fuse were replaced (all under warranty) and now the unit works properly.

Appologies that is all I have to contribute, but hopefully it helps somebody!
