I have a 95 GMC K2500 that has been giving me an intermittent ABS Light. I think its coming from the front left sensor. I'm not 100% sure and don't want to replace sensor unless needed. Does anyone know if this problem will store any codes in the computer, and if so, how do I get them, what do they mean and how do I clear them. I'm familiar with getting engine codes from the OBD-1 computer. Any help is appreciated.
