P0560

CIRCUIT DESCRIPTION
The power control module (PCM) monitors the system voltage to make sure that the voltage stays within the proper range. Damage to components, and incorrect data input can occur when the voltage is out of range. The PCM monitors the system voltage over an extended length of time. If the PCM detects a system voltage outside an expected range for the calibrated length of time, DTC P0560 will set.

CONDITIONS FOR RUNNING THE DTC
- Engine speed above 1500 RPM.
- System voltage below 9.0 volts or above 16.0 volts.
- Vehicle speed below 40 kph (25 mph).

CONDITIONS FOR SETTING THE DTC
- System voltage monitored at the PCM ignition feed circuit is less than 9 volts or more than 16 volts.
- Above conditions are present for more than 25 seconds.

CONDITIONS FOR CLEARING THE DTC
- The PCM will command the message OFF after one trip in which the diagnostic test has been run and passed.
- The history DTC will clear after 40 consecutive warm-up cycles have occurred without a malfunction.
- The DTC can be cleared by using the scan tool Clear DTC Information function.

ACTION TAKEN WHEN THE DTC SETS
- The PCM will not illuminate the Malfunction Indicator Lamp (MIL).
- The PCM will command a message to be displayed.
- The PCM will store conditions which were present when the DTC set as Fail Records data only.

DIAGNOSTIC AIDS

Important: Charging with a battery charger while starting the engine can cause DTC P0560 to be set.
