Circuit Description
Circuit 439 is 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.
