How to check APM for errors?

There are certain checkup points to see if the APM is still working properly.

 

First of all, connect through Micro USB, set the correct COM port and baud rate at 115200 but don’t click Connect yet, instead go to the Terminal on Mission Planner and select the APM from the dropdown box just below flight data, then click the connect button at the right of the dropdown box.
