Not starting code for U0019?

This might be tricky the code your getting u0019 is indicating that there's a communication problem with the can bus a problem with modules or some other part of the network not sending or receiving messages properly so it might be tricky here is a few things to get you started start looking for any broken or damaged wires connectors any sign that something's not right especially on the drivers side under the dash and near the fuse panel and engine bay if you were working on it recently go back to the area you were last working on it and see if anything's out of place anything unplugged or what not .. if you don't find anything you might need to take it into a shop that has a bi directional scan tool to really dig deep to find the problem there is a lot of things it can be at this point so fist look for the most obvious things ... that's a start...best of luck let us know what you find .

Yep, today's car don't like the amperage draw of a bass amp FYI. You will get codes like this.

Code: U0019 - Description: High Speed CAN Communication Bus (-) Low

I would recheck the wiring to make sure there is no damage because the code means one or more modules on the High Speed CAN bus detected an issue with the negative (low) side of the twisted pair CAN wiring.

The code I put up was the wrong one. The car still isn't starting checked a fuse it had two negatives, fixed that but car is still not starting it clicks and makes the sound like it's going to start but then doesn't. The battery is dead I'm not sure what else to do. The interior lights stay on when they are flipped off when the battery has a little charge
