How to tell an AYC failure

[Qke]

Hi,
can anyone share how to tell an AYC failure?

 

[TypicalGuy]

Diagnostic device can check all the code....

May I know what's VDO? Are you referring to rev meter?
Thx.

if you looking for ayc pump later,i got one...hehe

 

[TypicalGuy]

AYC lite on the dashboard will light on if AYC got problem..

u can go to EVO tuner and check in sunway...

use machine to test the computer

on the e7,e8 n e9 there is no indication provided for the ayc.only the acd will have a fault indication n that is if all the acd mode light lite up.for the ayc,u can check physically n the symptoms are difficulty to start or accelerate on slippery surfaces.but a sure way to chk the ayc is by diagnostic device MUT-II.u can even do the AYC and the ACD ops test with this device.

difficulty to start means bro?..

 

[BEan]

not sure myself.maybe sluggish or poor acceleration.to get better result is to use the MUT-II.

wat is the common part will spoil if acd light all turn on? can anybody answer me? it have been 1year im finding way to solve my acd prob..

 

[BEan]

usually its the acd pump or the 4wd ecu.seldom the light assembly.try hooking up the MUT-II tool lah.it will give out the fault code n u will know which component is defective.

i have try MUT-II b4 any d answer is ayc pump failure and i have try change ayc pump but problem still occur, im wori it will be my acd box failure... is there anyone have tis troble b4? how to solve it? i have try 4wd ecu, G-sensor, ayc pump, delay n also change whole dashboard wiring..

 

[BEan]
