I hooked car reader up and these are the numbers it gave;

  • U1120
  • P0700
  • P0562

Where do I start to troubleshoot this?

The codes indicate some trouble in your electrical system. Did I understand right, it starts and runs as long as the jumper-cables are connected, but does not run on its own?

  • Check your alternator - does it provide 13.8 volts?
  • Check for broken cables or signs of damage - could be a marten has broken some electrical connections.
  • Honest question: what is a marten? – Sam Jun 15 '18 at 15:27
