JK all warning lights flash dash dies for a second then car keeps driving no codes no check engine light
Watching. A year ago I replaced the stock base level radio with a head unit, 4 channel amp and powered sub. Battery was original. A month ago my vehicle started experiencing the same. Warning lights came on for 5 seconds and went off the message read check TPS system. But the code is never registered when I take it to the shop. I replaced the battery last week with an AGM Legend from Napa that was probably due to be changed but the problems persist
Troy I had the alternator changed as it was over charging the system and have had no problems since
Had issues with my 2015 having dash lights randomly flashing on. Ran across this video and have made this adjustment to my battery. Hopefully this will help. Connection was loose with the add on to the post. https://youtu.be/132xiZ_B8fU
I have a 2016 jk and I have same issue I have a wench heated seats and a new stereo an amp and speakers added and my dash warning lights all come on and they chime and the. Right back off, car keeps driving. I have no clue what could it be but I will try the alternator. Thanks!
Mine just did this about 5 minutes ago even my after market deck shutoff as well and had to reboot, so ima check battery first and if does it again I’ll try alternator and see if I happens again
