I recently got a clutch fitted to my evo 7, sence then all the lights for tarmac gravil and snow come on , this doesn’t happen all the time only if the car is idol for a few minutes, doesn’t happen when im driving the car and can i change to each different setting separately, anyone else have any experience of this happening?

 

Did you/they bleed your ACD line after it was disconnected for the clutch job?

 

Im not sure about that. Where is the acd line located? I also changed the transfer box oil but i dont think the correct oil was put in would that cause all the lights to come on?

 

Brass bleed nipple is on the underside of the transfer case. Check the fluid level in the boot reservoir, key on and then hold the accelerator pedal down to activate the pump. Have a helper under the car open the bleed nipple until there are no bubbles in the fluid coming out. Keep the ACD reservoir topped up so you don't introduce any more air into the lines during the process.

Once done key on and hold the accelerator pedal down again. The ACD pump should run and when it reaches pressure it should stop and the three flashing ACD lights should go out. If not your pump is shot and needs a rebuild.

 

Is that the AYC fluid? Seems to be low would this be causing the 3 lights to come on ? What fluid do i need to put into this ? Thanks for all your help

 

Yes - the ACD (Active Center Diff - inside the transfer case) and AYC (Active Yaw Control - inside the rear diff) are both fed from the pump below this reservoir. Make sure you top it up while bleeding the ACD line.

Use any quality Automatic Transmission Fluid rated SP-III or higher.
