Dash Warning Lights and Entune shuts off?

First off, I love my truck, so reserve the third gen hate for another thread. I searched but couldn't find anything regarding this issue. I have a 2017 DCSB TRDOR 6MT. Yesterday, while coasting to a stop, the Entune shut off and restarted, and at the same time, all the warning lights on the dash came on simultaneously (approximately 1-2 seconds) . It happened again today, except I was cruising around 35-40 mph. The engine stayed on both times. I have no modifications to the truck and checked for open recalls. It has 2500 miles so obviously its under warranty, but it is intermittent so it would help me if other people have experienced the same issue so I can describe the resolution to the dealer mechanic (who happens to be a friend of mine)

 

Might be a grounding issue.

 

I haven't heard of the dash lights coming on but others on here have had entune restart. I've had it happen about a half a dozen times when I first got the truck but it stopped and hasn't happened in about a year now. I thought a software update that came through had fixed it.

Electric gremlins are some of the most challenging to resolve. This stuff is starting to sound like the old days of GM and Chrysler.

 

Bingo. Dealer never tightened negative wire on battery. Problem solved.

 

Thank God it was so simple!

 

Glad it was an easy fix
