DTC Descriptor
DTC P0560 System Voltage

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 above 1,500 RPM.

Conditions for Setting the DTC
The ECM detects a system voltage out of range for 2 seconds.

Action Taken When the DTC Sets
^ The ECM will command the charge indicator and or warning message to be illuminated on the instrument panel cluster (IPC) and the driver information center (DIC), if equipped.
^ The ECM will not illuminate the malfunction indicator lamp (MIL).
^ The ECM will store conditions, which were present when the DTC set as Fail Records data only.

Conditions for Clearing the DTC
^ The ECM will command the message OFF after one trip in which the diagnostic test has been run and passed.
^ The history DTC will clear after 40 consecutive warm up cycles have occurred without a malfunction.

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

Circuit/System Testing
1. Measure the voltage at the battery terminals and compare it with the scan tool ECM Ignition 1 signal parameter. Verify that battery and Ignition 1 signal readings do not differ more than 1.0 volt.
^ If greater than the specified value, test the Ignition 1 and ground circuits of the ECM for an open/high resistance. If the circuits test normal replace the ECM.

2. Go to [Charging System Test].
