P0563 2021 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.

Code P0563 2021 Honda CR-V Description

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. However, the engine is not running because power for the gauges, the ignition, and the fuel pump is turned OFF by the power switch. When the PCM operates for a set time after the vehicle is turned to the OFF (LOCK) mode, it detects a malfunction and stores a Diagnostic Trouble Code (DTC). The DTC will be set when the PCM operates for at least 5 seconds after the vehicle is turned to the OFF (LOCK) mode.
