1	Did you perform the Diagnostic System Check - Vehicle?	-	Go to Step 2	Go to Diagnostic System Check - Vehicle
2	Install a scan tool. Start the engine. With a scan tool, observe the Ignition 1 Signal parameter in the Engine Electrical PCM data list. Does the scan tool indicate that the Ignition 1 Signal parameter is greater than the specified range?	11 V	Go to Step 7	Go to Step 3
3	Measure the voltage at the battery and compare it with the Ignition 1 Signal parameter. Are the battery voltage and Ignition 1 Signal readings different by more than the value specified?	0.8 V	Go to Step 4	Go to Charging System Test
4	Test the battery positive voltage circuit of the powertrain control module (PCM) for a high resistance. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 8	Go to Step 5
5	Test the ground circuit of the PCM for a high resistance. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 8	Go to Step 6
6	Inspect for poor connections at the harness connector of the PCM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition?	-	Go to Step 8	Go to Step 7
7	IMPORTANT: The replacement PCM must be programmed. Replace the PCM. Refer to Control Module References for replacement, setup and programming.Did you complete the replacement?	-	Go to Step 8	-
8	Review and record the scan tool Fail Records data. Use the scan tool in order to clear the DTC. Operate the vehicle within the Conditions for Running the DTC, as specified in the supporting text. 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?	-	Go to Step 2	System OK
