CIRCUIT DESCRIPTION

Circuit 439 is the ignition voltage feed for the PCM. Circuit 340 is the battery voltage feed for the PCM.

When 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.

A high system voltage will cause DTC P0560 to set, if the system voltage is greater than 16 volts for 2 seconds.


ACTION TAKEN WHEN THE DTC SETS

- All transmission output devices are OFF.

- The PCM freezes shift adapts from being updated.

- The PCM will 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 set DTCs.

- If DTCs set when you operate an accessory, inspect the applicable wiring for faulty connections. If DTCs set when you operate an accessory, inspect the applicable wiring for 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. Check the belt for correct tension.


TEST DESCRIPTION

The numbers below refer to the step numbers on the diagnostic chart.

4. Step 4 tests the charging system voltage.

5. Step 5 tests the battery voltage input at the PCM.

7. Step 7 tests the ignition voltage input at the PCM.
