Depending on what brand it still could fail again. Ask him about the turbo and when you look at it, looks at the turbo closely. Look for overheating

 

Brake light and ABS light are on for a reason. Just resetting them won't make them go away and not come back. The problem, whatever that may be, has to be fixed for them to stay off. Ask him if he has taken care of the killer dowel pin. The 12 valves and the newer 24 valves up to 2002 had that issue (12 valves for sure, not positive about 98.5-2002). But if its ran this long, he's likely taken care of it or just had luck on his side. If it hasn't been done, the timing cover comes off to fix it. Easy fix from what I've read about it.

 

Do you mean if the codes get reset they will come back after like a week of driving or do you mean if they get reset that they will come back immediately? The owner of the cummins just texted me today saying that he went to clear the codes and they are gone now. He had the code awhile ago, but since then has replaced all the brakes and pads, he just hasn't had time to reset them. He doesn't drive the truck that much, it just sits in his driveway while he drives his other truck every day, so I'm curious if I get the truck and drive it around for a few days, will the abs and brake light show back up? Or once they are gone, are they gone for good until something else goes bad?
Thank you

I'm going to look at the truck tomorrow at around 5 pm my time. Hopefully, all goes well and I bring it home, but if there are any other major issues with it I am still able to pass on it. let me know what you think please, and anyone else!

 

Code means something is wrong. Resetting it will just trip it again if the problem isn't fixed. Codes aren't thrown for brake pads. There is an issue and he is trying to hide it.

 

Most ABS issues cause the light to come on almost immediately, and it also clears as soon as something is fixed. I was still in my driveway after replacing the rear sensor and the lights went off. You could also just find a suitable surface and test if the ABS kicks in. CEL is a different story, typically codes go "pending" first and become "confirmed" after a while which then sets off the light.

Both trucks have some creative wiring under the hood, and on the gasser the intake connection from the fender well to the air filter box is missing (also check if the tabs on the back of the air filter housing are broken off). Neither are deal breakers but there's some work to be done.

 

He got back to me, he said he got it cleared, he drove it to work and home, and the lights didn't show back up. I think you have to drive it for like a week? I'm not sure, but if it doesn't pop up in a week then its good right? I think I'm going to go get it either way, because I still have the daily honda to drive around while I get that sorted out before the inspection. Please correct me if I'm wrong because I don't know for sure if thats correct ^

Edit: Didn't see your response until after I posted my reply, sorry. In that case, are there any codes that would go away and come back? I've always had a brake light and abs light on in both of my previous dodges, but I never really cared.

Is it possible something was wrong with the brakes until he fixed it, but the sensor was still triggered until he cleared it, meaning the sensor was still good but something else was wrong?

 

ABS lights can go off and come back. Mine did it. Mine was because I had a failing rear speed sensor. Then they would come in constant after changing that, turned out the rear brakes needed to be bleed.
