Lishoy,
All I can tell you is that the system is saying that the battery consumption is to much and that you may have a small capacity battery. I think you need to test your battery and check for falling cell voltages. Also check for voltage drop at the line contractors but a low. Battery will stop your line contractors operating. If you do the self diagnostic routine stage 7 will check the battery voltage automatically in the display it will either put up 08 or 07, 08 is a pass and 07 is a fail.
