E03 is a generic indicator or informational code indicating that a fault code exists or error. You will need to scroll through to the following screens to get the full fault code information. This one is just telling you that a fault has been detected but is not the actual fault code. It's a pleasure to help anyway I can.

Actual codes look more like this for example: DHH1KX

If you are in E mode on the monitor, E – 13 means backup lamp does not light or it keeps lighting up.
