2019 system errors

Today I installed a Cali Raised hidden LED light bar. Installed everything back to normal and the light bar works just fine. Now I’m getting all these notifications. I do have a OEM pro grill. Never had any issues with it before or the TSS. Can someone help me out? Really don’t feel like taking it to the dealer. Thanks.

 

First thing, disconnect light bar, then back track from there.

You won a prize!

 

Considering where you were working for the install, you need to check the harness going to the radar sensor in the grill. Reseat it and check it back to the main harness for damage. How did you power the lightbar?

 

ABS is likely the primary fault here, with all other warnings being subsequent

 

I had that occur when I was upgrading my HU and I did not get one of the connectors plugged back in properly. As they said before me, check it all and work back, you'll find it.

 

Best practices for Change Management say go to what changed last.

Street ball says 'do over'.

Your call.

 

Lightbar required you to take the grille off yes? if so, I would check the most obvious which would be if you plugged your TSS sensor back in. I had this exact problem when I installed my faux grille. Checked all plugs were in except the one at the top. I had the same warnings and everything. If sensor is plugged in in all the right places, unplug the lightbar and see if the warnings go away.

 

Words of wisdom.

 

Take it off and reset the battery. Also, it is good to check fuses if you haven’t fixed it by a reset. I know a good amount of people have had stuff like this happen but it is usually LED tail light bulbs or something like that. Generally an easy fix though. Let us know what you find!

 

Well boys after a day of trying to find answers, I took it into the dealer. A Misc communication wire was stripped when running the LED light bar wire through the fire wall. 280 dollars later and 4 hours at the dealer....my truck is back to normal. Word of advice....be careful running wires through your firewall.

 

Happy with the results though.

 

I'm happy to hear that they found and fixed your problem. Thanks for sharing the answer to the mystery.
