Ram 1500 Interior CAN Bus Fault 

I have been a retired tech for over 8 years. I have over 35 years of experience .I do believe I have learned more at watching your videos about can networks that all the training that I have over the years. Thanks for your knowledge charing

How satisfying to see that connector pin sticking out!

Amazing how a dc circuit assumes various voltages thru other paths when a critical ground is removed

I was a Chrysler tech in the 90's when they had the CCD bus system before CAN bus came out. I remember when more and more systems went to CAN bus communications. Chrysler had the best diagnostic scan tools beginning with the DRB2 then the DRB3

Great diagnostic, Jake! Effective process of elimination and a no parts required solution. Actually, 2 fuses required, but not for the original problem. Very interesting video.

Great fix. Had a 2018 Wrangler with a similar issue the other day. When I say the other day, I mean techs had been trying to find it for months as it was an intermittent stall no com. The real problem was the owner had all kinds of stupid aftermarket stuff wired inside with the disassembly for install causing damage to connector pins.

FYI, the VSIM module is Vehicle System Interface Module not used on 1500s. Optional on 2500/3500 pickups and standard on chassis cabs.

Im an engine builder but when i need a good dose of can bus diagnostics i come to your channel. Great video!

Great video! Thank you! I am about to dig into a similar problem in my 2015 Ram 3500. My Centre stack switch bank has not worked since I got the truck, and I am now having problems with my radio and blower motor. I appreciate a quick tour of the star connectors before I dive in. I am MUCH more equipped to navigate what exactly I am looking for now. Awesome!

Awesome work, jake! Thank you for taking the time to make these!

Another perfect diagnosis!

Thank you for this video. Since I retired in 2016 I've learned so much about CAN, LIN, LAN and others from You Tube videos like yours.

Excellent find as usual. Great video 👊🏻👍🏻 I had seen damage to wires under the seat. Because people thru their empty water bottles under seat and when another driver moved seat it cracked connector and plastic seat extension bar . That bar breaking was the only reason I found it .

Just impressive ! Thanks for making us learn more and gain more experience that easy ❤️

Great find! Thanks for bringing us along!

Thanks for bringing us along Jake. It's fun watching you ultimate techs solve the mystery. It would take me weeks and I still probably wouldn't find it.

All the bells and whistles are nice ...until they start ringing and blowing 🤪

Awesome video Jake you the man! Very meticulous and detailed. I need to get that scope for my Phoenix Plus.

I like your style Jake. Great video.

Brilliant Jake, another great diag. Thanks for sharing.

great diag Jake.

Nice one!

Great breakdown of the process that you use.thanks Jake

Great work

Great video and diagnosis. It sure was good to see that wire unpinned. I hate intermittent issues that fix themselves when you just touch something.

Great job Jake

Nice vid the air suspension on these trks is like the old lincolns they problematic leaks in system

Thanks for sharing your experience and being so thorough

You always have interesting diags

Great video.A satisfying find👍.

Fantastic job my man! Subscribed!!!

Great video!

Awesome video as always Jake!!

Excellent

Thanks a lot and respect

Nice. 👌

Great video, thanks. Air suspension - I think that came out in 1957. By 1958 there were probably kits to get rid of it.

great! performance

Nice detective work. But could we call this Loose Connectór factory Mistake? Or someone Has previously been there ? Anyways, customer's satisfaction is your priority!. Green Fix🤞🏻💯❣️

These exact symptoms on my 2013 Ram 1500. Turned out to be no comms to a trailer brake module.

Nice to see your back. Hope your trip went well with Megan. Thanks for sharing Jake. This was a good one . Artie 👍

Very nice diagnostic work, Jake. I presume you are using your TopDon Pheonix Smart? Any recommendation for a more cost effective scan tool for part time DIY diagnostician - something in the $700 range? thanks.

oh yes merc use the same little can piggy back blocks . absolutely awesome . makes diagnosing can much easier than the normal agro of either unplugging modules or jumping terminal blocks 👍👍 . actually used my scope this week pwn heater circuit 👌👌👌 worked a treat to determine one of tge mosfets had gone belly up in the controls .i did think of you as i was using it , thinking jake would be proud of me , pulling myself out of the dark ages and using a bit of tech . not my $2.00 test light and some bulbs on some ropy looking wires i have made 🤣🤣🤣🤣🤣

Love can ,one fault and all goes down, you find it and fix it all, become the bid hero 😂

Firts lije saludos desde Panamá

😊😊👍👍

Jake, what brand was that work light that you were using under the seat?

Do you know what that pin under the Seat was for?

Did you ever find out what that little box was that someone wired in under the seat? Thank you

Sounds like someone needed a Fues and stole one they thought were not needed

I have a question for you about my 2019 ram 1500. Is there a way I can communicate with you? If you don’t mind.

Just curious. What do you charge for a job like this. Excellent video.

How do you like the Topdon scope?
