CIRCUIT DESCRIPTION
The PCM monitors system voltage on the PCM ignition feed circuit. If the system voltage is out of tolerance, DTC P0560 will be 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 conditions are present for longer than 25 seconds.

ACTION TAKEN WHEN THE DTC SETS
^ The PCM does not illuminate the malfunction indicator lamp (MIL).
^ The PCM stores conditions that were present when the DTC set as Fail Records data only. This information is not stored as Freeze Frame data.
^ The PCM will default the transmission default to 3rd gear.
^ The PCM will inhibit TCC operation.

CONDITIONS FOR CLEARING THE MIL/DTC
^ A history DTC clears after 40 consecutive warm-up cycles have occurred without a malfunction.
^ DTC can be cleared by using the scan tool Clear Information function or by disconnecting the PCM battery feed.

DIAGNOSTIC AIDS
Check for the following conditions:

IMPORTANT: Be sure to inspect PCM engine grounds for being secure and clean.

^ A faulty connection at the PCM or the generator.
Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection. Use a corresponding mating terminal to test for proper terminal tension.
^ A damaged harness - 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 connectors and wiring related to the PCM, dash harness, and engine harness. A change in the display will indicate the location of the malfunction.

If DTC P0560 cannot be duplicated, reviewing the Fail Records vehicle mileage since the diagnostic test last failed may help determine how often the condition occurs that caused the DTC to set. This may assist in diagnosing the condition. For complete information and additional diagnostics for the vehicle charging system, refer to A Diagnostic System Check - Starting and Charging in Starting and Charging.

IMPORTANT: Charging with a battery charger while starting the engine can cause DTC P0560 to set.

TEST DESCRIPTION
Numbers below refer to the step numbers 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.
