A last test failed (current DTC) clears when the diagnostic runs and does not fail.
A history DTC clears after 100 consecutive malfunction free warm-up cycles.
The IPC receives the clear code command from the scan tool.

DTC B0560

Step	Action	Yes	No
Schematic Reference: Instrument Cluster Schematics Connector End View Reference: Master Electrical Component List
1	Did you perform the IPC Diagnostic System Check?	Go to Step 2	Go to Diagnostic System Check - Instrument Cluster
2	Install a scan tool. Start the engine. With the scan tool, observe the Engine Speed parameter in the IPC Data 1 data list. Does the Engine Speed parameter match the tachometer display?	Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems	Go to Step 3
3	Turn the ignition OFF. Disconnect the PCM connector C2. Install the J 33431-C Signal Generator and Instrument Panel Tester lead to the engine speed signal circuit at the PCM harness connector, and the other lead to a good ground. See Special Tools . Turn the ignition ON, with the engine OFF. Set the J 33431-C to generate a tachometer signal. Does the vehicle tachometer indicate an RPM reading?	Go to Step 5	Go to Step 4
4	Test the engine speed signal circuit for an open, a short to voltage or a short to ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 9	Go to Step 6
5	Inspect for poor connections at the PCM connector. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 9	Go to Step 7
6	Inspect for poor connections at the harness connector of the IPC. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 9	Go to Step 8
7	IMPORTANT: Program the replacement PCM. Replace the PCM. Refer to the following procedures: Powertrain Control Module (PCM) Replacement in Engine Controls - 4.3L Powertrain Control Module (PCM) Replacement in Engine Controls - 4.8L, 5.3L and 6.0L Engine Control Module (ECM) Replacement in Engine Controls - 6.6L (LB7) Engine Control Module (ECM) Replacement in Engine Controls - 6.6L (LLY) Powertrain Control Module (PCM) Replacement in Engine Controls - 8.1L Did you complete the replacement?	Go to Step 9	-
8	IMPORTANT: Program the replacement IPC. Replace the IPC. Refer to Instrument Panel Cluster (IPC) Replacement .Did you complete the replacement?	Go to Step 9	-
9	Use the scan tool in order to clear the DTCs. Operate vehicle within the conditions for running this DTC as specified in the supporting text. Does the DTC reset?	Go to Step 2	System OK
