u have to sent the car to a workshop with a mut-II diagnostic tool.that way u know which component is faulty.if there is no fault code found when diagnose with mut-II tool it could be the 4wd-ecu or the indicator lamp assy is faulty or the harness and connector is faulty.

anybody pls gave me more info, i hav change all gear oil d but problem still occur, is there any connector that maybe loosen? where to c?

like i said earlier.two or more indicator lights illuminating could indicate a 4wd-ecu failure or the indicator light assembly failure or wiring n connector fault.

to confirm 4wd-ecu failure,disconnect the two connectors connected to the 4wd-ecu.make sure all the acd mode indicator lights exthinguish.if the light remains illuminated,the 4wd-ecu is good.now its the indicator light assembly or the wiring n connector are faulty.

in case ur asking where is the 4wd-ecu.its under the carpet on the right hand side of the floor console.u might have to remove the floor console to gain access to the 4wd-ecu.

i cant tell u which wiring to check specifically since there r a lot of wiring n i dont have the wiring diagram.

hope that helps.

but i can tell which connector to chk.the combination meter connector and the 4wd-ecu connector.

will go n check it out now,thx,hopefully it solve the prob...

 

[orange]

cant find the ecu, ned to send for checking, by d way in tis case is d 4wd still working? o it jus d acd no function?

 

[BEan]

i'm not sure about that.but cant u find the 4wd-ecu near the floor console,underneath the carpet?evo 7 right?should be near the right side of the floor console.:hmmmm::hmmmm:

if it is due to wiring issue, can change the after market ECU including wiring, will that solve the problem ?

i think this is a typical AYC ACD scenario that has asked from time to time;
in short there are few types of generic scenarios:

1. You have just done a AYC oil change recently, and eveything seems fine until the 3 lights got lighted up abruptly.
Suspected cause: Inaccurate manner of servicing and changing AYC oil, thus resulting to unsuspecting air being trapped within the chamber linning of the AYC mechanism.

2. No oil change done recently but unsuspected long overdue AYC oil in operation: the AYC oil in use over here is the recomended originial Mitsubishi DIAQUEEN (if not mistaken on spelling), when AYC oil has been overdue (just like any other mechanical parts of the car, ie. engine oil, gearbox oil, front, center LSD oil over due = oil losing its viscosity and thus causing further WEAR n TEAR rate on the AYC controlled hardware !!)

3. Sudden electrical surge, due to incorrect wiring ie. Alarm fixing, gadgets fixing ie meters, ecu or voltage stablizer, ICE fixing....wiring is a sensitive issue, it can cause jerks, AYC lights, burnt fuse, abnormal surging tapping sound when boosting

4. Uneven wear of tyre, ie. tyre thread below recomended operating thread or areas in wheel base out of operating alignment;ie. lower arm, upper arm, bushing might be lose or worn off; thus disturbing to the wheel operation, the signals feedback may cause temporary 3 lights ON scenario too

in short the procedural way is to check via the MUTII or even the latest MUTIII which i heard is widely available; however having the tool to output with error codes is nevertheless effortless with a simple plugon, further diagnosis and resolution depends very much on workshop experience, which can be further subjective.

u can come to my shop to check this problem, or can call this no:012-6107616(kit)

me from pg how to go ur place check lol... it jus happen in sudden i think, din did any wiring installation thinggy oso, after it hapen i send to workshop 2change full gear oil n it still same, the acd light blink after i start drive bout 100m, when u close d ignition n restart it bek normal n when u drive almost 100m then it blink all bek... will this cause me very bad situation?

 

[evokit]

if then try to unplug the acd socket and try. if same i think u should change the ayc pump
things need to do first.
1) check diagnosis then check wat it says
2)try to bleed the acy pump
3)unplug the acd socket or acy socket
finally you know wat happen to your car. ok

 

[orange]

will try but i dunno where to look for d acd socket? perhaps some1 can lead me to d acd socket....

 

[DDgreystar]

hmm maybe with 3G teleconferencing can give real time online pictures :D

 

[orange]

wana crazy lioa everyday thinking of tis prob... by d way i hav a unit of e-manage for sale,item used for 3weeks oni, everything comes wif when i buy will go 2gather, anyone can help me get rid of it, oso got oem e9 suspension...

 

[evokit]

d socket is under d dashboard compartment n plugung with d acd ecu (black color)

 

[orange]

evokit: can pls specify me in detail? i look down under dashboard, wat i can c is d ecu... i cant find d black color acd ecu as u say...

 

[orange]

anyone help me...

 

[Not_Bad!!]

i have this problem also before...the 3 lights are on at the same time....
luckily i just take off the negative battery terminal n let it for 10 minutes n put it back n tighten it like usual....n the problem solve...thats just what i have tried...
