So today, i goto reverse my forge valve hose so instead of pointing towards the fan it points to rear, it basically slams against the battery and cables so i put it back to how it was, pumped tires up to 36psi all around..get in car, all acd lights are on...turn car off, drive a little they come back on...whats going on?

 

Try unplugging the negative of the battery , that will reset the computer. If the lights comeback on take it to the your nearest auto parts and have them pull the codes if possible.. good luck

 

But what would pullin batter realy do.

 

Reset the diagnostic codes. Search, this has been covered many times. Could be a bad acd pump, loose wire, bad abs sensor, air in the acd line.

 

Worst case scenario, the pump is bad. How much harm is it to drive like that?

 

It really could just be a coincidence. Try resetting the battery and seeing if the lights come back on.
36psi seems high all around, but it may depend on your wheel set up. Abnormal pressure or tread wear on the tires can throw off the system and trigger the lights to come on.
Do the lights come on during normal light driving or hard acceleration?
If they continue to come on you can get a diagnostic for it. Bleeding the system may help if there is an air bubble trapped. However, a diagnostic usually just says the pump is bad.
If you need to get it replaced i suggest contacting www.acdtuning.com for a pump or rebuilding yours.
Lastly, driving with the lights on does no harm to the car. The system is shut off and the car sinply acts like a 2003-2004 evo which does not have an ACD system.

 

+1 Didn't really think about that. Make sure they're all the same psi, if one is a lot higher than the rest it won't have the same amount of revolutions as the rest throwing it off, triggering the lights.

 

Big thanks for all the responses, so to make sure there is no harm with keeping the lights on except for handling? If the pump is bad ill just get a new one. Super thanks, i usually run 32 all around but lately my rear tires have been low. Lights come on during normal driving, i reset the battery so we'll see.

 

<p>Check the fuse for the acd pump its on the battery terminal.

 

As in fuse box?? Sorry im totally new to evos

 

To cycle the system for air just hold your gas pedal down in the on position before cranking, after u hear the pump cycle then start the car. This fixed my problem.

 

I did that..what does it fix?

 

You see the clear fuse on the battery terminal? That's the fuse for the acd pump. Alot of the time that's the problem.

 

Im an idiot but cant find it. Can you post a photo please

 

I had a problem with all the acd lights coming on, on hot days especially. I bleed the system and the problem wen away.
