Hi we are new here and also new to Peterbilt trucks. Had our 387 less than a year. First question I have is about the Peterbilt diagnostic software capability. When the truck is hooked up to the " computer' does it have the ability to diagnose a blown fuse and isolate where that fuse is located in the truck?
Who is authorized to use / own this software and does it require specialized training from Peterbilt? Is there a DIY version available to the average O/O?
I am looking for any and all input as it has just cost us a over 1400.00 to diagnose and replace a 13.00 fuse. I am looking for answers from anyone who has solid information on how the Peterbilt equipment works. Thanks in advance

Like all software it will point you in a direction then it's up to the mechanic to diagnose with other means using a digital volt meter and such. It might tell you the circuit has low voltage or similar. It can't be specific as telling you a fuse. The connector might be corroded or the harness might have a wire broke in two, etc. The software is only available to shops but there are bootleg copies out there. Then you need to know how to use it and interpret things. Then you need further diagnostic tools.
What was the original problem that made you head to a shop? We have a few good mechanics on here that could of probably saved you a lot of money if it was only a fuse. -
At this point I am trying to determine exactly what these high end computers do. We didn't just get repaired, we got raped. There has to be some way to circumvent this in the future without having to become a mechanic myself. I am angry at this entire chain of events and cannot imagine how the industry as a whole can justify or explain anyone having to pay over 1400.00 to diagnose and repair a blown fuse. To be fair, we were not and could not get to a Cummins shop ( they are closed on the weekends ) or a Peterbilt shop. Which is another rant... why do all these shops close at 5p.m and on weekends???? Aren't they a service industry? Shouldn't they be open when their customers are working. I don't suppose you know anyone who drives a truck after 6P.M. at night or on the weekends right?? -
It sounds like a little price gouging going on. It's important to get to your specific dealer if possible because of the different training and appropriate literature and specialty tools for you model. Not all shops are 100% up to date on all models.
I once broke down in the middle of nowhere. Truck just shut off and I coasted to the shoulder. I called my dispatcher in bed who was a well experienced former driver. He told me if it's not a fuel problem the only thing electrical that will keep a truck from running is the ECM is not getting power. Sure enough he was right. It took me a couple minutes to find the problem. The ECM wire has it's own battery hot and it's fused, runs through the ignition switch to the ECM. Many of the older trucks the ECM fuse was an inline fuse. You could trace the little hot wire off the battery and find it. Newer trucks they are putting them in the fuse panel. I bet that was your fuse. -

Ecm fuse is in the battery box...
-
the first shop's computer showed an error code that translated to ECM and they told us that. Should that have alerted them that is was the ECM fuse at that point?

Thank you all for your replies. I know now that we are in good hands!!

that's a friggin rip off
