please go to a workshop with an obd diagnostic reader for mitsubishi lancer evo to verify your exact problem.
when all ayc light up there should be error code stored in the 4WD ECU. Don't do guessing work.. that will cost you lots of wasted money and time... many had that kind of experience before.. so go to a workshop that have the tools to verify your problems and ask them if they could fix it for you or not... ok? good luck!

 

[kojai]

Sent to workshop already but no false finding.

 

[ftzone]

did the workshop did a diagnostic test with the OBD scanner? If Mitsubishi is called MUT-II.
if all the ACD lights were ON there should be a fault code... how come no fault readings?

 

[kojai]

Just found d 60a fuze putus, replaced but d lite still on, how

HI Kojai,

1. Try reconnect to a different MUT-2 and see if code 82 or 45 (if not mistaken) pop up.
2. Make sure correct ACD fluid and is sufficient.
3. Bleed the ACD electronically (MUT) or manually.
4. Check pressure sensor/switch (at the boot if not mistaken) and relays.
5. Check fuse at the battery (+) terminal.
6. Check ACD ecu and its wiring, socket not fried. (bottom passenger side)
7. If all above checked, your hydraulic pump is on the way to heaven i.e KONG!

p/s have u had a clutch changed recently?

Hope it helps.

Ta!

as for mine, all the light came out last year.. sent to the mitsubishi dealer and they said that my ayc motor was dead.. if wanna change to new one need around 8k but if don't want to it is okay as i am not bringing the car for sports driving.. so, still doesnt change it till now..

 

[ftzone]

oka887, you can source for a used pump.. not that expensive until 8K lor..

 

[kojai]

Just bought used ayc pump, hopefully it will solve d problem, ecu checked already, let u all know later

 

[oka887]

i live in japan now.. used one is around half of the price not included with the　service charge..

check with mutII 16 pin diagnostic tools.the error code suppose to come out.when did last time u change yr ayc fluid?try check ayc fluid level.bleed ayc fluid,change transfer oil,diff oil,check the ayc pump pressure.
Actually it is recommended to change ayc fluid every 7000 km with mmc atf spIII dynaqueen.
