CIRCUIT DESCRIPTION
Circuits 439 is the ignition voltage feed for the Vehicle Control Module (VCM). Circuit 440 is the battery voltage teed for the VCM. If the VCM detects a low voltage, a high voltage for a long time, or a high voltage, for a short amount of time, then DTC P0560 sets. DTC P0560 is a type C DTC.

CONDITIONS FOR RUNNING THE DTC

System Voltage Low
The engine speed is greater than 1,500 RPM.

System Voltage High
No engine speed needed.

CONDITIONS FOR SETTING THE DTC

System Voltage Low
One of the following conditions exists for greater than 15 seconds.
^ The system voltage is less than 10.5 volts at a maximum transmission temperature of 152°C (305°F) or:
^ The system voltage is less than 6.7 volts at a minimum transmission temperature of -40°C (-40°F).

System Voltage High
The system voltage is greater than 19 volts for 10 seconds.

ACTION TAKEN WHEN THE DTC SETS
^ The VCM does not illuminate the Malfunction Indicator Lamp (MIL).
^ The VCM causes an immediate landing to second gear.
^ The VCM turns off the PC solenoid valve.
^ The VCM inhibits the TCC engagement.
^ The VCM freezes the shift adapts.
^ The VCM records the operating conditions when the Conditions for Setting the DTC are met. The VCM stores this information as Failure Records.
^ The VCM stores DTC P0560 in VCM history.

CONDITIONS FOR CLEARING THE DTC
^ A scan tool clears the DTC from VCM history.
^ The VCM clears the DTC from VCM history if the vehicle completes 40 warm-up cycles without a non-emission-related diagnostic fault occurring.
^ The VCM cancels the DTC default actions when the fault no longer exists and the ignition switch is OFF long enough in order to power down the VCM.

DIAGNOSTIC AIDS
^ First diagnose and clear any engine DTCs or TP sensor codes that are present. Then inspect for any transmission DTCs that may have reset.
^ Charging the battery with a battery charger and jumpstarting an engine may set this DTC.
^ Inspect the generator belt condition and tension.
^ Inspect the connectors at the VCM, the Underhood Fuse Relay Center and all other circuit connecting points for an intermittent condition. Refer to Testing for Intermittent and Poor Connections in Diagrams.
^ Inspect the circuit wiring for an intermittent condition. Refer to Testing for Electrical Intermittents in Diagrams.

TEST DESCRIPTION
The numbers below refer to the step numbers on the diagnostic table.
6. This step tests the charging system voltage.
7. This step tests the battery voltage input at the VCM.
8. This step tests the ignition voltage and battery voltage inputs at the VCM.
