Diagnostic Instructions

•	Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.

•	Review Strategy Based Diagnosis for an overview of the diagnostic approach.

•	Diagnostic Procedure Instructions provides an overview of each diagnostic category.

Diagnostic Fault Information

Circuit	Short to Ground	Open/High Resistance	Short to Voltage	Signal Performance
IGN I	P0562	P0562	-	-
Ground	-	P0562	-	-

The engine control module (ECM) 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.

Conditions for Running the DTC

•	The vehicle speed is above 8 km/h (5 mph).

•	The system voltage is between 9.5-18 V.

Conditions for Setting the DTC

The ECM detects a system voltage above 16 V for less than 1 second.

Action Taken When the DTC Sets

•	The charge indicator turns ON.

•	The driver information centre (DIC) displays the SERVICE BATTERY CHARGING SYSTEM warning message.

Conditions for Clearing the DTC

DTC P0563 is a C type DTC.

Diagnostic Aids

•	A possible cause of this DTC could be overcharging with a battery charger or 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 C1 battery terminals. The voltage should be between 12.6 and 15.0 V

⇒	If not within the specified range, refer to Charging System Test .

Engine running, observe the scan tool ECM Ignition 1 signal parameter. Verify that the scan tool displays a value that is within 2 V of the battery terminal voltage.

⇒	If not within the specified range, replace the K20 ECM.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
