DTC Descriptor
DTC P0563: System Voltage High - ECM 12 VDiagnostic Fault Information
Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
|---|---|---|---|---|
B+ | P0562 | P0562 | -- | -- |
Ground | -- | P0562 | -- | -- |
Circuit/System Description
The engine control module (ECM) 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.
Conditions for Running the DTC
The engine is running.
Conditions for Setting the DTC
The ECM detects that the 12 V battery voltage is greater than 16 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
| • | Some possible causes of this DTC are overcharging with a battery charger and jump starting. |
| • | A high voltage value in multiple modules indicates a concern in the charging system. |

Circuit/System Verification
- Engine running, accessories OFF, measure and record the battery voltage at the 12 V battery terminals. The voltage should be between 12.6 and 15.0 V.
- If all circuits test normal, replace the ECM.
| ⇒ | If not within the specified range, refer to Charging System Test. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.

Typical Scan Tool Data
Circuit | Short to Ground | Open | Short to Voltage |
|---|---|---|---|
Operating Conditions: Ignition ON, engine OFF. Parameter Normal Value: 12.6 V | |||
B+ | 0.0 V | 0.0 V | 12.6 V |
Circuit/System Description
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.
Conditions for Running the DTC
The ignition is ON.
Conditions for Setting the DTC
The FPCM detects that the 12 V battery voltage is greater than 16 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.

Circuit/System Verification
- Engine running, accessories OFF, measure and record the battery voltage at the 12 V battery terminals. The voltage should be between 12.6 and 15.0 V.
- Observe the scan tool FPCM Ignition 1 Signal parameter. The reading should be between 12.6 and 15.0 V.
| ⇒ | If not within the specified range, refer to Charging System Test. |
| ⇒ | If greater than the specified range, replace the FPCM. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
