1	Did you perform the Diagnostic System Check - Vehicle?	-	Go to Step 2	Go to Diagnostic System Check - Vehicle in Vehicle DTC Information
2	Install a scan tool. Turn ON the ignition, with the engine OFF. With a scan tool, observe the Ignition 1 Signal parameter in the powertrain control module (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 6	Go to Step 3
3	Using a scan tool, compare the Battery Voltage parameter in the DIM data list with the Ignition 1 Signal parameter in the PCM data list. Is the battery voltage and PCM Ignition 1 readings different by more than the value specified?	0.5 V	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?	-	Go to Step 7	Go to Step 5
5	Inspect for poor connections at the harness connector of the PCM. Refer to Testing for Intermittent Conditions and Poor Connections andConnector Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 7	Go to Step 6
6	IMPORTANT: The replacement PCM must be programmed. Replace the PCM. Refer to Control Module References in Computer/Integrating Systems for replacement, setup and programming.Did you complete the replacement?	-	Go to Step 7	-
7	Review and record the scan tool Failure 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
