Hi sorry, I'm new and this forum is a little confusing so sorry if I'm posting in the wrong spot. I picked up a 97 Acura CL 4 cylinder. It sets an ABS light after about 30-60 seconds of starting. I can hear the ABS pump running for about 30-60 second after start up then it shuts off and the ABS light pops on. I've topped off the fluid in the ABS unit and bled the ABS system to no avail. I pulled the code and got code #1 "ABS pump motor Overrun". I've found a step by step for a similar problem in a honda forum but the ABS set up in the pics is different than my acura. ABS Code 1 - The fix with pics - Honda-Tech
It seems like the accumulator isn't building pressure but I can't seem to easily find a part number or confirm what will repair it. Does anybody have a fix? Links? Clues? Pics? Small explosives? Anything?
Thanks
