Expert Reply:
On a Prodigy P2 trailer brake controller # 90885 the error code PL indicates power loss, that the controller is losing its 12V power connection to the battery while your foot is on the brake pedal.
The operating power to a brake controller is carried on the black wire, which typically connects through a circuit breaker to the positive battery terminal.
You will want to check all connections for that black power wire. Start at the plug at the back of the controller; look for a bent pin that may not maintain full contact with the mating conductor. You could also have some corrosion or trapped foreign material on the plug. Also check the connections at the circuit breaker and battery. The issue could be as simple as a loose ring terminal or mild corrosion, both of which are easily remedied.
The installation/operation instructions for the Prodigy are linked for you along with two helpful articles.
