P0560

Circuit Description
Circuits 439 is the ignition voltage feed for the Vehicle Control Module (VCM). Circuit 440 is the battery voltage feed 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 D DTC.

Conditions for Running the DTC

System Voltage Low
The engine speed is greater than 1500 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 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
^ 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 condition and 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.

Test Description
4. This step tests the charging system voltage.
5. This step tests the battery voltage input at the VCM.
6. This step tests the ignition voltage and battery voltage inputs at the VCM.
