P0563 2018 Honda CR-V Code - Powertrain Control Module Power Source Circuit Unexpected Voltage
Quick Answer
If there is a short to ground in the harness between the Powertrain Control Module (PCM) and main relay, the main relay stays ON even if the vehicle is turned to the OFF (LOCK) mode, and the PCM remains active. Common causes include Faulty Powertrain Control Module (PCM) Main Relay (Integrated in the Relay Circuit Board), PCM Main Relay harness is open or shorted, PCM Main Relay circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
