Viewing inactive codes 2012 VNL 780

yes i need to know the inactive codes than i can tell you where to look if you have computer hooked up and take a test drive at the same moment its happening it will tell you where to look at the fault that becomes active, best thing you can do is look at the count of the fault that will give you a good indication if its something that is happening all the time or only some of the time.

 

I have attached the image below that shows the results.

 

So the middle code has 18 counts that’s what I look into first could be a few different Causes from clutch getting stuck to cca to ribbon harness also air system not operating properly on the trans side. Hope this helps.

 

Thank you so much, God bless you.

 

I’m glad everything is good with the truck how is the truck doing on power and fuel any changes.
