3,Power-on inspection

Only high voltage runs without limiting heater performance.

After turning on or resetting the heater, the heater waits for a power request on the CAN bus, and once a valid power request is received, the power-on check starts.

First, check the total current with all the heating circuits of the heater inactive. If it exceeds the predetermined value, the heater is not working at this time, so this fault indicates a short circuit, leakage current or open circuit fault.
