CIRCUIT DESCRIPTION
Circuit 339 is the ignition voltage feed for the Powertrain Control Module (PCM). Circuit 440 is the battery feed for the PCM.

If the PCM detects either a low system voltage or a high system voltage for a short 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 exist for greater than 15 seconds:
^ 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).

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

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

CONDITIONS FOR CLEARING THE DTC
^ A scan tool clears the DTC from PCM history.
^ The PCM clears the DTC from PCM history if the vehicle completes 40 consecutive warm-up cycles without a non-emission-related diagnostic fault occurring.
^ The PCM 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 PCM.

DIAGNOSTIC AIDS
^ First diagnose and clear any engine DTCs 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 DTCs.
^ Inspect the connectors at the PCM, 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
