I pulled two codes from my brother-inlaws truck.
One was the CEL, vehicle speed sensor 2flashes pause 2flashes I believe it is.
Then i got an abs code 4 fast flashes then 1 long flash, I think this is pressure dump valve rite?

If it's only one code it will flash over and over again rite?

Thanks

We watch Scotty just at the moment I don't know. I have some paper books on this age and next time there will try too look up what you found. Guess right now w ABS it might be getting a wrong signal as to how fast each wheel is turning but don't know for sure. Hang in there - someone is likely to have a better clue with those codes,
