Instrument Cluster ( Gauges ) going Crazy, J1939 DATA BUS not Responding on a School Bus

in this video I will share with you how to diagnose a J1939 CAN BUS NETWORK on a Blue Bird School Bus

[@ShabaleetoIV]

This is one of the most informational videos on the J1939 especially coming from someone who doesn’t work on these thing regularly I really appreciate it!

More about the Freightliner school buses, please.🤗 As a German you don't get to see them so much, so I find the topic interesting 👍

[@KITS_Auto_and_Truck_Repair]

mxssm thanks, there will definitely be more videos about school buses coming up...

[@ClosingTheTruckingGap]

That was a good video. Now I understand the CAN BUS system

[@KITS_Auto_and_Truck_Repair]

[@flabianog1386]

This is a great video. Very helpful for a studying technician.

[@grantbenjaminiv6377]

Looking forward to more,I’m currently in school for diesel tech,,you did great explaining it brother thx!!! This helped me

[@KITS_Auto_and_Truck_Repair]

Grant Benjamin IV My Pleasure!! I'm glad to hear that the video was helpful!! There will be more videos coming up! stay tuned!

[@am.b5688]

They won't teach you this in school! Read the books and get all the training you can get after school! The school will build your base, so its not bad!

[@kuribe87]

Hello, if I have the same problem, but my resistors are good, where would you look next.

[@KITS_Auto_and_Truck_Repair]

@kuribe87 check for an open or a short in the network. what resistance value did you get at the DLC?

[@Z14kt12timandjes1]

I really like how you redrew that circuit to make it easier to understand. That certainly helps us learn. Thank you so much. Excellent content you are producing.

Beautiful job mon général ! Who needs a scope anyway lol

Hi bro, you did a great technical explanation with lots of tips. Plz, how can i get a soft copy that can decode the VIN of trucks? Thanks for your videos as we look forward to more. 🚛

Great video. Any idea what would cause just gauges (speed and fuel) to be incorrect on 2007 bluebird with CAT C7

Mark Anderson a Ground problem can cause that!

I have a 1999 Vanhool t2145 with same dashboard problem. I'm in Dallas Texas can you recommend someone in my area?

Jesse Romero I don't know anyone in your area, unfortunately!!

[@jesseromero3580]

@@KITS_Auto_and_Truck_Repair ok thank you. You seem very knowledgeable keep up the good work! I enjoy your videos very much! Now is there an external device and app that i can connect to my j1939 port and create basically a second digital dashboard that i can display using a tablet and be able to read my gauges with that while i figure out how to fix my dashboard? Something like blue fire perhaps? Any recommendations?

I have a 1994 international school bus 3800 DT466, and the miles do not roll as the bus moves. I bought the bus in this condition. Any idea what causes the miles not to move? Thank you.

[@KITS_Auto_and_Truck_Repair]

Cesar Orozco I have a video on this channel that shows how to fix that kind of problem, it's on a freightliner school bus, look for that video, this problem can be caused by a defective vehicle speed sensor or the wiring etc...

What scanner do you use for the Cat C7? Our 2003 motor home is a Freightliner with a 3126E (predecessor to the C7). The Cat E.T. software is very expensive. Is your scanner a generic one that works with different brands of engines. Thanks

[@KITS_Auto_and_Truck_Repair]

Rick L yes I use a Diesel Laptop to scan the buses and medium duty vehicles that I work on!! they have a big variety of scan tools for school buses, you should check them out!!
