I noticed that the yellow ABS light is constantly on. The truck has about 50K miles and I am not sure when the light came on or if it has always been on.It is now driven very few miles because of operating cost.Are there OBD2 error codes that might help me find what is causing the light to light? Any other ideas suggesting where to start looking for the cause? I would not care that the light is on but here in Massachusetts, we have annual inspections and mine is due next month.
