    Default ABS problem

    The service ABS System light is on in my car,fluid level is fine.Ive tried several scanners and the only code I get is 12 and then nothing after that,Ive been told the paper clip in terminals A-H wont work for the ABS system.Ive got the FSM to read the trouble codes so all I need is to pull the code.

    You don't say which scanners you've tried. Many scanners do not support the EBCM on a 91. A few do and you may need one of them. There are five DTCs ABS IIS may send which cannot be read with flash-code diagnostics.

    I'll add that you've been told wrong about flash-code diagnostics. The instructions for that are in the article here on the CAC which is listed below. For detailed diagnosis and service instructions for ABS-IIS see:

    Ive talked to at least 5 shops and basically got 5 answers to how to pull codes,Ill find the problem sooner or later.The FSM says the paperclip and terminals terminals A-H will display DTC but the info provided here says it may or may not.I just want the code then Ill fix it.
