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 the PCM detects 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 1000 RPM.
- The system voltage is less than 10 volts at a maximum transmission temperature of 150°C (302°F).
- The system voltage is less than 7.3 volts at a minimum transmission temperature of -40°C (-40°F).
- All conditions are met for 4 seconds.

A high system voltage causes DTC P0560 to set, if the system voltage is greater than 17 volts for 2 seconds.

Action Taken When the DTC Sets
- All transmission output devices are OFF except the Torque Converter Clutch (TCC) Pulse Width Modulated (PWM) Solenoid Valve and the 32 Shift Solenoid Valve Assembly.
- The PCM freezes shift adapts from being updated.
- 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 belts for damage. Inspect the belt for correct tension.
