DTC P0560 System Voltage 5.7L and 7.5L Gas
Circuit Description
The circuits 439 and 441 are the ignition voltage feeds for the VCM. Circuit 440 is the battery voltage feed for the VCM.
When the VCM detects a low voltage, a high voltage for a long time, or a high voltage for a short time, then DTC P0560 sets. DTC P0560 is a type "D" DTC.
Conditions for Setting the DTC
System Voltage Low:
| • | The engine speed is greater than 1500 RPM. |
| • | The system voltage is less than 10.5 volts at a maximum transmission temperature of 152° C (305° F). |
| • | The system voltage is less than 6.7 volts at a minimum transmission temperature of -40° C (-40° F). |
| • | All conditions met for 4 seconds. |
If the system voltage is high then the system voltage is greater than 19 volts for 4 seconds.
Action Taken When the DTC Sets
| • | The VCM causes an immediate landing to second gear. |
| • | The VCM turns off the PC Sol. Valve. |
| • | The VCM inhibits the TCC engagement. |
| • | The VCM freezes the shift adapts. |
| • | The VCM does not illuminate the Malfunction Indicator Lamp (MIL). |
Conditions for Clearing the DTC
| • | A scan tool can clear the DTC from the VCM history. The VCM clears the DTC from the VCM history if the vehicle completes 40 warm-up cycles without a failure reported. |
| • | The VCM cancels the DTC default actions when the fault no longer exists. |
| • | The VCM cancels the DTC default actions when the ignition is cycled OFF long enough to power down the VCM. |
Diagnostic Aids
| • | Charging the battery with a battery charger and jumpstarting an engine may set this DTC. |
| • | If this DTC is set when an accessory is operated, inspect for faulty connections or an excessive current draw. |
| • | Inspect for faulty electrical connections at the starter solenoid. |
| • | Inspect for faulty electrical connections at the fusible link. |
| • | Inspect for loose or damaged terminals at the generator. |
| • | Inspect the generator belt wear and the generator belt tension. |
| • | First diagnose and clear any engine DTCs or TP Sensor codes that are present. Then inspect for any transmission DTCs that may have reset. |

Circuit Description
Circuit 439 is the ignition voltage feed for the PCM. Circuit 440 is the battery feed for the PCM.
When the PCM detects a low voltage, a high voltage for a long time, or a high voltage for a short time, then DTC P0560 sets. DTC P0560 is a type D DTC.
