P0560
DTC P0560
Circuit 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 input can occur when the voltage is out of range. The ECM monitors the system voltage over an extended length of time. If the ECM detects a system voltage outside an expected range for the calibrated length of time, DTC P0560 will set.
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC P0560 System Voltage
Conditions for Running the DTC
* System voltage is below 11 volts or above 16 volts.
* Engine speed is above 1,500 RPM.
* Vehicle speed is below 40 km/h (25 mph).
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 not illuminate the malfunction indicator lamp (MIL).
* The ECM will command the charge indicator to be illuminated on the instrument panel cluster (IPC).
* The ECM will store conditions which were present when the DTC set as Failure 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.
* The DTC can be cleared by using the scan tool Clear DTC Information function.
