No ABS Codes?
Used the paperclip jumper method to check my CELs but my ABS light didnt flash, just stayed lit up. Does this mean there isnt a code for whatever is causing the ABS light? Im guessing its a wheel speed sensor that is dirty or something, but without a code im not sure where to start looking? Does this mean there isnt a code or do you have to do something different to get ABS codes?

Re: No ABS Codes? (HOOKSH)
I think your '97 has the same system as my '95. That's all I've done to get an ABS code, what I don't remember is what happens when there isn't an error. For example when I jumper it to check spark timing, I think(?) the ABS light doesn't even come on. (Not sure when I'll get a chance to check that.)

Re: No ABS Codes? (HOOKSH)
So your ABS light was on or came on while driving and you jumped the diagnostic connector to retreive the ABS code, but no code was stored, is that right?
That is the exact same problem I'm having. The Helms manual has a whole troubleshooting procedure just for that situation. What it means is that there is not a problem with any of the hardware or ABS components (because if there was, it would register a particular trouble code), but rather there is an electrical problem somewhere in the system. Because of the electrical problem, the fail-safe relays have been triggered and it disables the ABS system until the problem can be fixed.
Basically the troubleshooting procedure entails checking for voltage and continuity at various points along the ABS circuit path, from the battery, to the ABS fuse box by the modulator/pump, back to the ABS brain, and all the way up to the alternator.
My problem started shortly after installing a remanufactured alternator, so I am thinking the alternator could be the cause of my problem.
My old alternator caused my battery light to be on, only while the car was turned off, and the oil pressure light would flash continually when the engine was running. The remanufactured alternator fixed both of those problems, but now I have this ABS problem.
Until I get around to trying to get another alternator, I just pulled the ABS bulb out of the guage cluster because it was annoying as hell. I just have to remember when I'm driving that I have no ABS.
