P0560

Circuit Description
The powertrain control module (PCM) monitors system voltage on the PCM ignition feed circuit. If the system voltage is out of tolerance, DTC P0560 is set. When the conditions that set DTC P0560 are present, operation of some vehicle systems and components may be affected.

Conditions for Running the DTC
The engine is running.

Conditions for Setting the DTC
^ The system voltage monitored at the PCM ignition feed circuit is less than 9 volts or more than 16 volts.
^ The above condition is present for longer than 25 seconds.

Action Taken When the DTC Sets
^ The PCM stores the conditions which were present when the DTC set as Fail Records data only.
^ The PCM defaults the transmission to third gear.
^ The PCM inhibits TCC operation.

Conditions for Clearing the MIL/DTC
^ A history DTC clears after 40 consecutive warm-up cycles have occurred without a malfunction on.
^ DTC may be cleared by using the scan tool Clear Info function or by disconnecting the PCM battery teed.

Diagnostic Aids
Inspect for the following conditions:

Important: Verify that the PCM engine grounds are secure and clean.

^ A faulty connection at PCM. Inspect the harness and connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, or faulty terminal to wire connections.
^ Inspect the wiring harness for damage. If the harness appears to be OK, observe the Ignition 1 voltage display on the scan tool while moving the connectors and wiring related to the PCM, dash harness, and engine harness. A change in the display indicates the location of the malfunction.

Important: The use of a battery charger while starting the engine may cause DTC P0560 to be set.

If DTC P0560 cannot be duplicated, reviewing the Fail Records vehicle mileage since the diagnostic test last tailed may help determine how often the condition that caused the DTC to be set occurs. This may assist in diagnosing the condition.

Test Description
Number(s) below refer to the step number(s) on the Diagnostic Table.
13. This vehicle is equipped with a PCM which utilizes an Electrically Erasable Programmable Read Only Memory (EEPROM). When the PCM is being replaced, the new PCM must be programmed.
