DTC P0560

Circuit Description

The PCM monitors the system voltage to make sure that the voltage stays within the proper range. Damage to components, and incorrect data input can occur when the voltage is out of range. The PCM monitors the system voltage over an extended length of time. If the PCM detects a system voltage outside an expected range for the calibrated length of time, DTC P0560 will set.

Conditions for Running the DTC
Conditions for Setting the DTC

The PCM detects a system voltage out of range for 2 seconds.

  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
  3. With a scan tool, observe the Ignition 1 Signal parameter in the PCM data list .

Does the scan tool indicate that the Ignition 1 Signal parameter is greater than the specified range?

11.0V

Go to Step 6

Go to Step 3

3

Measure the voltage at the battery and compare it with the Ignition 1 Signal parameter in the PCM data list.

Are the battery voltage and PCM Ignition 1 readings different by more than the value specified?

0.5V

Go to Step 4

Go to Charging System Test

4

Test the battery positive voltage circuit of the PCM for a high resistance. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.

Did you find and correct the condition?

Important

The replacement PCM must be programmed. Refer to Powertrain Control Module (PCM) Programming in Engine Controls-3.8L or Powertrain Control Module (PCM) Programming in Engine Controls-5.7L.

Replace the PCM. Refer to Powertrain Control Module (PCM) Replacement in Engine Controls-3.8L or Powertrain Control Module (PCM) Replacement in Engine Controls-5.7L.

  1. Review and record the scan tool Fail Records data.
  2. Use the scan tool in order to clear the DTCs.
  3. Operate the vehicle within the Conditions for Running the DTC as specified in the supporting text.
  4. Using the scan tool, observe the Specific DTC Information for DTC P0560 until the test runs.

Does the scan tool indicate that DTC P0560 failed this ignition?
