The PL code on a Prodigy P2 # 90885 means the controller is losing power on the black wire when you press the brake pedal or use the manual override. It's likely caused by a loose connection with the black wire so that's the first thing to check.

It's also possible you have a bad circuit breaker that the black wire is connected to the battery through.

I've also linked a help article on troubleshooting brake controllers for you.
