After realizing this we opened up the HV battery cleaned the boss bars and the nuts boxed it up. But still the energy flow arrows were not showing after driving it for 30 km intense driving and error code or there is a cable which is not connected at the 12th volts battery. It's a blue and paper cable.
I'm not sure what you're saying here? Did you have a warning light with an error code or not? And if you did what is the error code? Also disconnecting the 12v battery for a minute will do a factory reset on your car and its the easiest way to fix a glitch like this.
His 12V battery harness is broken partially, which is probably what's causing missing data (I don't even know how) that is normally fed to the energy monitor.
