Code P0562 2017 GMC Sierra Description

The Powertrain Control Module (PCM) continuously monitors the system voltage. The system voltage information is taken from the PCM's ignition feed circuits. Voltages below 8.0 volts or above 17.1 volts cause improper system operation and/or component damage. If the system voltage is low the PCM raises the idle speed in order to increase the generator output. The PCM disables most outputs to protect the hardware if the system voltage is high. A scan tool may not display data if system voltage is outside this range. The Diagnostic Trouble Code (DTC) will be set if the PCM detects a too low electrical system voltage level.
