DTC P0560

Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle (Initial Inspection and Diagnostic Overview) prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis (Initial Inspection and Diagnostic Overview) for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions (Initial Inspection and Diagnostic Overview) provides an overview of each diagnostic category.



DTC Descriptor
DTC P0560
- System Voltage




Circuit/System Description

The powertrain control module (PCM) 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 PCM detects a system voltage out of range for 2 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.

Circuit/System Verification

Engine running, observe the scan tool PCM 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 PCM Ignition 1 signal parameter. Verify that battery and Ignition 1 signal readings do not differ more than 2.0 volts

• If greater than the specified value, test the Ignition 1 circuit X1 terminal 19 and ground circuit X2 terminal 73 of the PCM for an open/high resistance. If the circuits test normal replace the PCM.

2. Go to Charging System Test (Charging System Test) .



Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
