Hey.
Check that the pump (pumps) is working.
There are only three of them.

I don’t know how to check the pumps with ELM327 in ForScan :-(
There are no tests

Error cleared using FordScan?
How fast does it reappear?
What are the conditions of occurrence?

ForScan clears the error. The error comes back after driving a few kilometers, sometimes during normal driving, sometimes as fast as possible or turning on the heating.

And if standing on the spot to turn on the stove to the maximum, an error will appear in a few minutes?
I want to help you, I have the same car and ForScan
if we can determine the conditions under which the error appears, it will be clear which pump is not working

I turned on the HI / HI heating and waited for 10 minutes. Climate shows 5+ kW / Other 0.3kW, Trip 1 I used 1.5kW. Heating works ok. Do not show "See manual". What's next?

P0C4A:00 indicates the PCM is detecting a short to power, ground, or an open on the PWM output. The pump is controlled by a PWM signal giving it variable speed capability. This pump is for the battery coolant. It is located near the firewall on the left hand side of the motor. It is terminated at the PCM which is on the right hand side of the motor compartment, near the front. One of these might be loose, or have some contaminates inside. It could also be damaged wiring or a bad pump/pcm.
Check this pump, wire and plug.
