Circuit Description

Circuit 439 is the ignition voltage feed for the PCM. Circuit 340 is the battery voltage feed for the PCM. If the PCM detects a low voltage and a high voltage, then DTC P0560 sets. DTC P0560 is a type D DTC.

Conditions for Setting the DTC
The system voltage is low:
- The engine speed is greater than 800 RPM.
- The system voltage is less than 10 volts.
- All conditions are met for 2 seconds. The system voltage is high:
- The system voltage is greater than 16 volts.
- The TFT is greater than 0°C (32°F).
- All conditions are met for 2 seconds.

Action Taken When the DTC Sets
- All transmission output devices are OFF.
- The PCM does not illuminate the Malfunction Indicator Lamp (MIL).

Conditions for Clearing the DTC
- A scan tool can clear the DTC from the PCM history. The PCM clears the DTC from the PCM history if the vehicle completes 40 warm-up cycles without a failure reported.
- The PCM cancels the DTC default actions when the fault no longer exists and the ignition is OFF long enough in order to power down the PCM.

Diagnostic Aids
- Charging the battery with a battery charger may set DTCs. Jump starting an engine may falsely set DTCs.
- If DTCs set when you operate an accessory, inspect the applicable wiring for faulty connections, and excessive current draw.
- Inspect the starter solenoid for faulty connections. Examine the starter solenoid fusible link.
- Inspect the generator for a damaged terminal.
- Inspect the accessory belts for damage. Check the belts for correct tension.
