This morning going down the road my tach dropped to zero RPM, my Check guages light came on as well as the Seat Belt, Airbag, Highbeam, Engine, ABS, and oil light All came on. Truck still ran fine but my truck just kept dinging and all the lights kept flash and the truck would drop to 0 and go back to normal and drop again with every ding. Any idea's as to what might be wrong? thanks

 

did the speedo and other guages all drop to 0 also?

 

I'm not 100% sure about the speed since i was at a deadstop when it started, but the other guages were working.

But i shut the truck off and removed key and opened my door to shut all the electronics off then started the truck back up and it quit. So i don't know if it was a one time thing?

I was wrong about one light, it wasn't the oil it was the e brake, my bad idk why i thought it was the oil light. Went out to start truck again and see how it acted and now it dings louder than it use to before you start it and the Check gauges, E-brake, high beams, ABS, and Engine lights all stay on, and the RPM's drop to zero and raise back up to normal every ding like before. But the truck idles just fine, no weird noises, so the problem has to be electrical. I'm not entirely sure.

 

that is REALLY weird, i have no clue but hope you get it figured out soon

 

good luck with it i saw one on you tube like this dont know what caused it he has video of it while he was driving

 

Clean all your ground terminals!

 

Anyone have a wiring diagram for the 07's? I'm not exactly sure where all of my ground terminals are.
