Some of you (especially Vigman) may know that I have had problems with the ABS on my car, i.e. I've extracted numerous fault codes from the DIC including code 71 [ABS ECM internal fault].
I am just wondering, especially as there have been a couple of recent ABS posts from fellow members, that my problem may be related to the fact that my brakes have recently been bled (?)
I replaced the fluid with DOT4 recently (my manual recommends DOT3 but I thought that's just because DOT4 didn't exist when my car was made [1990]) I wonder if I may not have bled the system satisfactorily.
My ABS motor runs for ages (probably about 45-60 seconds) before setting the "service ABS" light while it is self-diagnosing after startup.
Anyway I had just ordered a new ABS ECM but have just been told by my supplier that the part is not available except as a rebuild of my unit so I cancelled the order as I'd rather fit a replacement before sending mine off to the states (I'm in the UK and I may be without my unit for ages).
I'm going to try and rebleed the system when I get the chance (may not be for a few days).
Anyone got any thoughts or experiences on the fluid theory? Could this be why my ABS motor runs for so long?
Thanks folks, without your help I'd be in trouble. There aint many REAL Corvette experts in the UK!
