Jeep wrangler CAN-C canbus error FIX - replace STAR connector

Our 2019 Jeep wrangler JLU was throwing every possible error code on the dashboard and sometimes was unsafe as a result. The dashboard would completely freak out and sometimes the engine would die. After 2 months at the dealer we got fed up and decided to take matters into our own hands. The errors were related to the Canbus, specially the CAN-C data bus that most of the computers use to communicate in the Jeep and many other Mopar vehicles. Some folks on the Jeep wrangler forums had reported that replacing the STAR connector behind the glovebox fixed their issue. I’m happy to report that indeed it fixed our problem as well. Does your Jeep behave like shown in this video, showing every error on the dash? Check out how we fixed it.

We used Jeep J-scan and an OBDLink MX+ Bluetooth adapter to read and clear codes:

Been having Can Bus issues for months dealer quoted me 800+ to recheck all the wiring and replace it. Glad I found this will give it a shot appreciate the video.

The dealerships have very few real technicians anymore. I'm glad that you finally got it fixes. Me friend says that they find lots of pin fitment issues with the can bus data connections. Sometimes just unplugging and plugging it back in fixes the issue. Crazy stuff with these new vehicles. Thanks Scott!

Thanks for sharing detailed video. My 2018 JL had same very concerning issue and I was able to have dealer fix in a few hours under extended warranty. Jeep should recall the part!

I’m having the same issues with my 2018 Jeep JL, I will give this a shot, thank you

Just changed mine, and it immediately cleared the abs and traction control lights on my dashboard after starting the vehicle! All I had to do is clear the check engine code with my tuner.

A litte tip for next time. Start with the second row, as you can use a small flathead to pop off the connectors by depressing the small flap facing the rear. Once the second row is removed, this will give you access to the rear of the first row where you can use the small flathead to get the pins.

Good to see you. Hope all is well with you and yours. I am somewhat averse to buying new vehicles just because of that. I have a friend who owns a mechanic shop and get to hear the stories regularly.

This is the best channel on YouTube! Can’t wait for another Quartzite run!

[rbencik]

Awesome video. Running out to het the part and replacing it. Hopefully it will fix the issue. Thank you.

[JimTilman-tnpi]

Thank you for your video. My 2018 Rubicon had the same issue. I was able to fix it.

[jimgreeson]

This is a well know problem. IDK how the dealer and jeep "don't know about it"

[JT-zhwr]

Have the same issue contacted the dealer months ago.. they were so busy that the tech just told me to replace this after I explained all the codes and all the issues I was having

[HN]

Really appreciate this video. I also took my Wrangler to the dealership after the exact same symptoms. They failed to fix it, instead telling me they did a software update.
How in the world do they now know about this known issue that's all over the internet? I imagine this will be the last Jeep I ever buy.

[glennman]

Good to see you making another video Scott!

[loug]

Thank you for this detailed video. I am have the same issue. Just ordered the part.

[TopNoTchVSOP]

I removed my glove compartment and I did not a no CanBus connectors for my 2018 JKU sport in that location.

[multicamchannel]

Is your jeep good after changing this? My 2019 is having the same problem. Its even locked up a couple of times to where i couldn't even get it in gear. All the warning lights are randomly coming on and off. Its been in the dealership twice and still not fixed. I just ordered this part from your link, and i hope to god it fixes it.

[sestabr]

Same issue with mine. 2020 happens now and then. Got a new canbus but haven’t switched yet.

[AnarchyChaos]

Did you disconnect the battery or just swap vehicle off

[daleolson]

They had the same problem on Apollo 13. Try the luner lander

[photoapeal]

I had the same issue today, it said service shifter, then it lost power steering everytime service shifter came up, trying to wheel 37's off the highway without power steering assist is not fun. I have a feeling that it's the CAMBUS. I had 16 error codes.
