So today I was driving and I noticed that all of my ACD lights were on. I pulled over and shut the car off and turned it back on. Seemed fine for about 2 min and then they came on again. I checked the ACD fluid and it is at max. I have about 22k miles on it but I shouldn't have to change the fluid for another 8K. I read that sometimes it can be ABS sensors and I am going to check those tomorrow. I really need to do my breaks do you guys think that the breaks being close to gone could cause this? Any other ideas?

Thanks,

Josh

 

Pull the cable off the battery let it sit for 10 mins. See if it resets. If not you can bleed the ACD system. Just need 2 people to do it.

 

Cool I am going to try to disconnect the battery tomorrow and see if that helps. With only 22K on it do you really think that the pump could have gone bad already?

 

mine just started 2day as well, great coincidence

 

Did u mess with your throttle position sensor? I put on a ported TB and because I didn't put the TPS back in the right position all 3 lights pop on EXACTLY like your's does. After about 2 mins of driving.

 

No I haven't changed anything about the car in about a year.

 

Has it been warmer in Chicago lately? My ACD works fine in the winter months, and then all the lights come on in the warmer months. From what I've read this is due to the pump failing to make the required pressure to satisfy the system pressure relay. In short, the pump is bad. I've also read of people adding oil thickeners to get more time out of it. This is why it works in the colder months....colder oil has much thicker viscosity.

 

Bring it in to a dealer! I had the same issue and it was a bad ABS sensor covered under warranty!

 

Bring it to the dealer, they'll tell you what's wrong with it.

 

if you need an acd pump because its bad i have a good one for sale lmk

 

So today I haven't had any issues with it. I disconnected the battery and cleaned my air filter. I guess we'll see how things go over the next few weeks. I'm replacing pads and rotors tomorrow since mine are totally shot. I'll keep you guys up to date.

 

mine comes on during the first downstroke of my windshield wipers without fail

 

So the lights came on again yesterday. Dropped it off at the dealer and sure enough it's the ACD pump. Warranty replacement without an issue! Thank god.

 

and there is a updated relay for the ACD pump as well. Hope they used the newer part number on that.

 

Yeah I hope so. The part is on order right now so they said that it should be here next week. I do have another question though. The dealer told me to take the car home and driving it until they replace the pump is fine. Is that true? Am I going to damage anything else if I continue to drive it??
