PL Error Code on a Prodigy or P2 Trailer Brake Controller on a 2001 Ford F-350
Question:
Our Prodigy screen all of a sudden showed a P.L. and we are wondering what the meaning of it is. Please give is an answer and help us figure out what is going on with the screen. Thanks.

Expert Reply:
The PL error code on the P2 # 90885 and Prodigy 90185, indicates that the power was interrupted while the brake pedal was pressed.
This means that when you apply the brakes the voltage is not getting back to the trailer brakes.
This can occur for a number of reasons. First check the brake controller wiring and all of its connections to the vehicle. A bad splice or corrosion could cause this error. Then check the wiring going back to the trailer connector for any corrosion or breaks in the wiring and check the trailer connectors on the pin and behind where the wires attach for corrosion and dirt.
On the trailer side, do the same with the connector and wiring. Make sure all grounds are attached to clean and corrosion free bare metal surfaces. You can also test the brake magnets using the FAQ I have linked for you.
