DTC P0560 System Voltage Malfunction (1 Of 2):

DTC P0560 System Voltage Malfunction Low (1 Of 2):

System Voltage:

CIRCUIT DESCRIPTION

Circuit 1642 is the fused battery feed for the Powertrain Control Module (PCM). Circuit 439 is the ignition feed for the PCM.

When the PCM detects a low voltage, or 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 more than 800 RPM.

^ The system voltage is less than 10.0 volts for 2 seconds.

The system voltage is high:

^ The transmission temperature is more than 0°C (32°F).

^ The system voltage is more than 16.0 volts for 2 seconds.


ACTION TAKEN WHEN THE DTC SETS

^ The transmission defaults to 3rd gear.

^ The PCM inhibits Torque Converter Clutch (TCC) operation.

^ 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 could set DTC P0560. Jump starting the vehicle could set DTC P0560.

^ If DTC P0560 sets when you operate accessories, inspect the applicable system for poor connections or excessive current draw.

^ Inspect the accessory drive belt for wear or incorrect tension.


TEST DESCRIPTION

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

2. The battery voltage must be above 10.5 volts before proceeding with this table.

3. This Step ensures that there is no problem with the generator.

5. This Step tests for high resistance in the battery feed circuit to the PCM.

7. This Step tests for high resistance in the ignition feed circuit to the PCM.
