TOWN & COUNTRY CARAVAN NO BUS DIAGNOSTIC
ฝัง
- เผยแพร่เมื่อ 4 เม.ย. 2019
- Customer brought in a 2014 Chrysler Town and Country minivan. The vehicle runs and drives fine, but many of the accessories were not working. The windows were not operating, the radio / navigation screen head unit was not turning on, the A/C controls were not operational, the windshield wipers stayed on continuously, the steering wheel control buttons were not working and there was a message on the instrument cluster display that said “NO BUS”. In this video I take this opportunity to share my knowledge about CAN BUS communication systems and how troubleshooting these errors can be simple. This should also apply to Dodge Caravan owners.
Thank you for watching!

Thank you so much for this video, you probably saved us 100s of dollars at the repair shop. We have a Town and Country S minivan that had the same problem. It started after washing the vehicle. The problem was the drivers side rear door where the connection got wet from power washing. Again, thank you!!
That was an awesome diagnostic process! Definitely a lot of manual labor involved, but so satisfying to see the CAN network come back to life :)
2014 Town & Country also with a No Bus error. Took off fuses one by one until I pulled off the M34 10A fuse which solved the No Bus error. This fuse is part of the following circuits: Park Assist, Heater Climate Control Module, Headlamp Wash, Compass, Rear Camera, Door Lamps, Flashlight, etc. Anyone have suggestions on how I should proceed with finding out which of these accessories are faulty?
very good your videos! Another easy way to identify problems in the Can network would be to turn off the “star connects”, so you can identify which module is bringing down the network
I found out that unplugging the connection like in your video (the plug in my rear DVD) that it also corrected my no bus code. However my blind spot monitoring and some other functions are now not working. What should I do next??? Thanks
could u have tried doing bidirectional control of the different systems with your picoscope or verus?
Hey, what did you have to replace on the car to fix the problem? I detached the connectors like you showed and the issue went away, but I don't know if I have to replace that whole unit attached to the ceiling, or just the monitor, or just find the wire and wrap it with electrician tape...
We have a problem very close to this. But the difference is that I turn on the rain wipers, and the meter stops, lights, speedometer, and the men's temperature indicator help me.
Hello, I have a Dogch Dart from 2013 and it has the same problem, except that everything is removed from mine and it runs normally and then the same thing happens again an hour later and it doesn't start.
How do you disconnect on slide doors?
Fantastic explanation of your troubleshooting methods! Great to mention that modules can interfere with one another! People often forget that a BUS is a shared resource that any module can mess with.
Thanks for this video. Had the issue pop up the day my Caravan turned 100,000 miles. I found this video and started by disconnecting the rear DVD monitor and ac. The DVD monitor was causing the No Bus code. Saved me tons on dealership diagnostic costs. Excellent video!
WOW! Thank you so Very Much! I've been pulling my hair out trying to figure this same problem out. And, also I had a problem with the Tailgate Lift & it would not open manually. Not sure if that was also a problem with your customer's vehicle. I bought this 2008 T&C with a "3 day warranty" ,, UGH! I called Dealers and friends to find an answer. I was stuck away from home with this problem. 6 hours later, when I happened to pull the driver's side cargo door closed... Boom! everything lit back up and the van was back to normal. Next day(today), the ghost was back again. And you have now kept a grown man from crying! Thank you so much. I was asked if the van had been in a flood, because that causes some wonky things to happen. You were very educational, but WAY over my head. Thank God that you put this video up, and I can be helped a year later. And thank your customer, too.
Nice fix. Good thought process and explanation of your work. One slight shortcut is that you can unplug each front door in the jamb without having to pull door panels, saves a few precious minutes
Just finnished doing my Smog Update CAN Communication Diagnostic Course, I thought this was an AWESOME Video... You are a great teacher and very knowledgeable and it's the best explanation I have seen... Thankyou Keep it up...
You sir, are an automotive deity! This was 100% the problem with our 2016 Grand Caravan. I fixed the problem in about 10 minutes max
Bravo Sir. This video needs to be noticed ASAP. Wonderful presentation. I'm just scratching my head about not having splices. That radio interface to me looked like Chrysler's powerNet thing they have going on where the splices are under the glove box tucked up in there. I know the Darts have them. But u were there present at that time so I'm pretty sure u are right that it didn't have splices. Bravo again Sir. Hope the big dawgs in the TH-cam world take a look at this. Bless 😇
Best video I have found for understanding BUS & Module systems Thank you
That’s a great find, thing is with these kind of faults they are so time consuming( I do it every day)but the customer just doesn’t see it ... well done 👍
You are a great teacher, knowledge, methodology, energy ...👍 well done
