Battery positive voltage is supplied to the powertrain control module (PCM) even when the ignition switch is OFF. The battery positive voltage is used for the PCM keep alive memory and the air-fuel ratio adaptive control memory. If DTC P0560 is set, the PCM will not store any other DTCs.

No battery voltage detected at the PCM battery positive voltage circuit for at least 3 seconds.

DTC P0560 is a type A DTC.

1. Ignition ON, observe the DTC information with a scan tool. DTC P0560 should not set.
2. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.

1. Ignition OFF, disconnect the X4 harness connector at the PCM.
2. Ignition OFF, verify a test lamp illuminates between the ignition 1 voltage circuit terminal X4-3 and ground.

⇒	If the test lamp does not illuminate, test the ignition 1 voltage circuit for a short to ground or an open/high resistance.

3. If the circuit tests normal, replace the PCM.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
