I was driving down the interstate a couple days ago and i hit a bump in the road and my E Brake light flashed and stayed on along with the ABS, ESP, and BAS lights...Also, my speedo quit working along with my fuel gauge which fluctuates from full to empty. What would cause this to happen? Other than i just hit 70k miles and my warranty is gone.. My jeep is sitting on 37's, coil overs, bypass shocks, etc.. So this small bump i hit could have been a big bump that i couldnt feel with my shocks.. But its nothing that i havent done before seeing as i drive that same interstate almost every day. Ive got a few codes throwing.. Lost Communication with ABS Module, Small Evap Leak, Large Evap Leak, Lost communications with Dynamic Sensor (Which i replaced and it didnt go away), and a Wheel Speed Sensor Code. I can clear all of these and right as i turn the jeep back on they all come right back except for the evap codes sometimes stay off for a couple days... Any help would be appreciated to clear these codes and dash lights..
Bad connection at the ABS wires on one of the wheels? I would check them all. I had one go bad a couple of years back and had to have it replaced, caused the lights to go on, but speedo still worked.

I do not consider myself a smartass. I point out the obvious, search for the truth, and speak fluent sarcasm. I am, by experience, an accomplished curmudgeon.
Fuses. I pulled mine to try and turn traction off permanently and it said my e brake, abs, traction were all off and my speedo stopped working. Check your fuses and try to get the code from a code reader.

I had the same problem after a week of running trails. I read the above and checked
the wiring at each wheel, feeling for loose connections/shorted wires.
Could not find anything wrong and started up the Jeep to check lights again and they were off.
If/when I get the lights again, I will check for lights after checking each wheel to narrow it down more.
