Stepping Out With My Own Numbers

Did you check the pig tail out?

 

Yes. They have a couple machines they use here to check the signal and the only spot that can't receive or send was the chassis harness for the ABS. Everything was good. There is a wheel sensor that needs to be replaced too. It got caught up in the brake and broke the line going to it. My trailer has disc brakes and no one around here has it, only drum brake parts around here.

 

This will be more expensive than I thought. The trailer wheel sensor is only 75 bucks and the guy says it might take an hour. No big deal there but this ABS harness on the truck is a big deal. It will be 700 for the part itself and then an estimated 6 hours labor to get it in. Peterbilt has been a disappointment since I bought this truck. I really don't want to drop money on this thing right now because I have something in the works I'll be sharing soon. This is really bad timing for this sort of thing to happen. I can't let it ride though because of the ABS fault. Can't afford any CSA points, should DOT see it.

 

So before you spend $700 on a new harness, check your abs primary fuse. When you hit the brakes and the trailer abs light comes on, it's a good chance it's going through the backup fuse. I had that issue in my freightliner earlier this year, every time I hit the brakes the trailer abs light would come on. Come to find out it was the primary abs fuse. Worth a look at least.

 

Was your fuse blown?

 

Yep it was.

 

From the truck ABS module back was good, from the pigtail back was good, but the harness was dead. They had several machines there to test signals across the components and the only one that was unable to send or receive signals was at the harness. The truck computer and fuses are good but the signal stops at the harness. They spent several hours tracking down where I was losing signal in the ABS system. I don't know what devices they were using but there were three different things, and a laptop, plugged into my truck while he was doing his checks

Everything should be done really late tonight or very early tomorrow. I'll look to roll out mid day Wednesday.

 

All fixed up. It wasn't cheap either but the system is working like it is supposed to now. I won't say what the final bill was but I've had a headache all day from it.

The guy at Great Dane told me that it looked like the two sensors that were causing trouble on the trailer had been replaced before and whoever did it didn't leave enough slack in the lines to the sensor which was causing it to get pinched by the brake. One was broken due to the pinching and on the other he was able to put an extension on it so the same thing wouldn't happen.

After that he had to recalibrate the Utility Roll Stability. Because my ABS was jacked it messed that up too. No parts needed there just labor to go through the testing procedure to get it right.

A friend of mine is finally back in business moving freight and has me on two loads that pay stupid money and I'll end up in Ohio. Also got Centramatics put on my trailer finally. That made my day somewhat better.

 

Now I've got injector codes popping up. This is really bad timing. Getting back to Arkansas by early next week to have them tested and find how many are bad and replace. No performance issues yet but that doesn't mean anything. If you get fuel in the oil you can ruin a motor.

 

@Misesian how many miles are on the truck?
