Ok guys so like the title says. I have an issue with the ACD. the other day all three lights came on. now before we yell about searching, let me preface that I have. and none of the symptoms discussed fit the bill. It is erratic and more prone during hot days. The first occurrence was in 95* heat in stop and go traffic. car cooled that night lights went away and been driving it no issue. The light came back today and reset every time the car is turned off.

With the ignition on and pressing the throttle I can get the pump to prime as it should. So I do not think its the pump. The lights come under weird circumstanced. When I hit a good bump in the road or let off the clutch a little hard it triggers the lights. Almost as if the ACD has a knock sensor and the lights indicate a bump. That is the only way I can describe it. the car drives fine, I have not really put it through the ringer while the lights are on, but i have been able to go through the gears, take corners with no issue, and accelerate at highway speeds without any fuss.

If anyone has any insight to how I may trouble shoot the issue without the MUT tool that would be great. I am going to try to bleed the system tonight and see if that helps. Thanks in advance guys

 

speed sensor

 

mmm. I will look into that. Also, I bled the system, I could be wrong but if I recall correctly, when you hit the throttle with the ignition on it primes the pump and bleeds the fluid. BUT while doing this the pump did prime but only drained fluid with the throttle pushed down. Does that make sense?

 

If your vehicle is fairly stock it should be cover under warranty. One of your speed sensors has a loose connection/is going bad.

 

I recently had to repair the front right ABS sensor. severed it somehow while going pretty hard in full lock. repaired the wire by soldering new pins into the harness. Though when I put the scanner on the car, it doesnt show anything in the ABS system. Fairly stock??? eh, look at my signature. Not sure how the stealership will feel about that. Besides the wheel sensors for the ABS which others?

 

Those three lights come on in my car as well, only when it is hot though.
