DTC Descriptor

DTC P0563

-
System Voltage High - FPCM

Diagnostic Fault Information






Circuit/System Description

The fuel pump control module (FPCM) monitors the system 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.

Conditions for Running the DTC

The ignition is ON.

Conditions for Setting the DTC

The FPCM detects that the system voltage is greater than 17.5 V.

Action Taken When the DTC Sets

DTC P0563 is a type C DTC.

Conditions for Clearing the DTC

DTC P0563 is a type C DTC.

Diagnostic Aids

* A high voltage DTC in multiple modules indicates a concern in the charging system.

* This DTC could be set by overcharging with a battery charger or jump starting.

Circuit/System Verification

1. Engine running, accessories OFF, measure and record the battery voltage at the battery terminals. The voltage should be between 12.6 and 15.0 V.

• If not within the specified range, refer to Charging System Test Testing and Inspection.

2. If all circuits test normal, replace the FPCM.

Repair Instructions

Perform the Diagnostic Repair Verification Verification Tests after completing the diagnostic procedure.
