Wish I knew ! Exactly the same problem I am having which is why I found yours. All indictions to me seem to be an electrical problem (ground maybe). I have checked all I could think of. Even replaced battery and alternator. Crank sensor next and then cam sensor. This is due to the fact that both codes showed for these.
dash lights and tail lights cut out
They have problems with the door switches.
You have a bad ground to the from the glow plug relay to the engine block
rear indcater lights very dim but ok when hazzards are on
The only thing that will work with key OFF is the brake lights,head lights and emergency flashers. Dome light will also work.
Because both computers have detected problems and set trouble codes.
A low battery can cause the electrical system to flash check engine lights
Spark plugs are electrical components that should not have contact with any sort of fluid. The engine warning light is on as a warning for a possible electrical system issue.
Sounds like a dead car battery. Do any lights or electrical accessories work?
Warning lights come on when there is a problem. An Engine management light comes on when there is a problem within the engine, that may cause problems later.
If you are speaking of lights using electrical current for power, it would be electrical technology.
Its your wires they are not connected properly you have what it is called a short or a not connected wire this will cause other problems like flickering lights and other electrical problems
