DTC Descriptor
Diagnostic Fault Information
| Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
|---|
| IGN I | P0560 | P0560 | -- | -- |
| Ground | -- | P0560 | -- | -- |
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 instrument panel cluster (IPC) illuminates the charge indicator.
Conditions for Clearing the DTC
DTC P0560 is a C type DTC.
Diagnostic Aids
| • | A low voltage DTC in multiple modules indicates a concern in the charging system. |
| • | 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 measure and record the voltage at the battery terminals. Verify that the battery voltage is 12.6-15.5 volts.
- Observe the scan tool ECM Ignition 1 Signal parameter. The reading should be between 12.6 and 15.5 volts.
Circuit/system Testing
- Ignition OFF, disconnect the harness connectors at the ECM.
- Ignition OFF and scan tool disconnected, open and close the driver door, and wait 1 minute. Test for less than 5 ohms between the ground circuit terminals listed below and ground.
- Ignition ON, verify that a test lamp illuminates between the B+ / ignition circuit terminals listed below and ground.
- If all the circuits test normal, replace the ECM.
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
