Circuit/System Description (FPCM)

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The fuel pump control module (FPCM) monitors the 12 V battery voltage to ensure that the voltage stays within the proper range. Damage to components, and incorrect data may occur when the voltage is out of range. If the FPCM detects that the system voltage is high, DTC P0563 sets.
