DTC Descriptor
DTC P0560 System Voltage

Diagnostic Fault Information






Circuit/System Description
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 below 40 km/h(25 mph).
^ The system voltage is below 11 volts or above 16 volts.
^ Engine speed is greater than 1,500 RPM.

Conditions for Setting the DTC
The ECM detects a system voltage out of range for 5 seconds.

Action Taken When the DTC Sets
DTC P0560 is a C type DTC.

Conditions for Clearing the DTC
DTC P0560 is a C type DTC.

Diagnostic Aids
A high or low voltage DTC in multiple modules indicates a concern in the charging system. Refer to [Charging System Test]. Charging System Test

Circuit/System Verification
Engine running, observe the scan tool ECM Ignition 1 signal parameter. The ignition 1 signal parameter should read between 11.5-15.5 volts.

Circuit/System Testing
1. Verify DTC P0560 is set as current.
^ If the DTC is history, refer to [Charging System Test]. Charging System Test

2. Measure the voltage at the battery terminals and compare it with the scan tool ECM Ignition 1 signal parameter. Verify that the battery and Ignition 1 signal readings do not differ by more than 2.0 volts.
^ If greater than specified value, test the ignition 1 circuits X2 terminal 5, X2 terminal 54 and ground circuits X2 terminal 1, X2 terminal 2 and X2 terminal 4 for an open/high resistance.

3. If all circuits test normal, replace the ECM.

Repair Instructions
