Thanks for looking. Recently, my Abs light came on and I got the code which is 53(five long blinks and three short blinks) for my 97 prelude. So, I did everthing the Helms manual says but to no avail. I changed the Pump relay along with the Abs control unit also this seems to happen when it's very hot outside. I'm about to give up and take it to the Dealer, which I can't afford, but before I do so I'd like to know if anyone's had this issue and what the remedy was.
