B0560

CIRCUIT DESCRIPTION
The IPC monitors the engine speed signal to determine the tachometer position. If the IPC determines the engine speed signal voltage is out of the normal operating range, a DTC will set.

CONDITIONS FOR RUNNING THE DTC
- The engine speed is greater than 800 RPM.
- The ignition voltage is greater than 9.0 volts, but less than 18 volts.

CONDITIONS FOR SETTING THE DTC
- The IPC detects that the commanded state of the driver and the actual state of the control circuit do not match.
- The above condition is present for at least 5.0 seconds.

ACTION TAKEN WHEN THE DTC SETS
The IPC stores the DTC in memory.

CONDITIONS FOR CLEARING THE DTC
- 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.
