1989sligo yeah that's what I am thinking/hoping. I need all new brake lines anyways so I will just do it then. I will be sure to post failure or success here.

9297oldram The valve is probably froze up then if it was sitting for that long.

1989sligo Okay great. The truck sat for 10 years before I bought it so I don't doubt that is the issue

9297oldram When the valve goes bad that's what usually sets off the light so replacing the valve will probably shut the light off.

1989sligo Yeah, I know. I am going to throw a valve unit at it. Not too bad at $100 on RockAuto and redo the brakes and brake lines and bleed it really good. If the light goes off, great, if not I will concede defeat, unplug the box, and move on.

9297oldram That's why everyone just unplugs the black box and doesn't worry about it.

1989sligo No matter what I do I cannot get the light to flash. I found the diagnostic connector and it has one pin inside. I grounded that to many different places with the key in the "run/on" position and no flashing. Every grounding point I tried was a good ground and I waited up to 5 minutes with each so I am somewhat lost on it.

9297oldram What ever happened with this in case someone else may want a RWAL fixed?
03-19-2019 12:55 PM
1989sligo Oh awesome thank you also, I turned the key to the on position and grounded out the single pin on the diagnostic connector and I could not get any codes to flash, it just stayed solid lit. I grounded to the glovebox light, battery terminal, and engine block, and nothing.

Bschwarzli I will also add there is 9 codes the box will spit out. 9/10 times, I have found it to be greenrot in the sensor cable that goes between frame connection and axle.

9297oldram It's like I tell everyone that's dead set on something " it's your truck you can do what you want with it ". Even though we know of better ways of fixing things then Dodge did from the factory we can still help fix them to factory. This issue is just one of many on these old 1st Gens.
