Injector Solenoid Test
The purpose of the injector solenoid test is to diagnose injector wiring and injector solenoid functionality.This test identifies an open circuit or a short circuit in the circuit for the injector solenoids. The test activates the injector solenoids one at a time while the engine is not running. A good solenoid will create an audible click when the solenoid is activated. Cat ET indicates the status of the solenoid as "OK", "Open", or "Short".Cylinder Cutout Test
The cylinder cutout test allows one cylinder or multiple cylinders to be cut out. The cylinder cutout test is useful when troubleshooting poor engine performance or a suspected injector failure.The cylinder cutout test disables the injector by not providing the injector pulse to the solenoid. The cylinder cutout test can be performed on one injector or multiple injectors at once.Wiggle Test
The purpose of the Wiggle Test is to detect intermittent electrical faults in electronic control systems. The Wiggle Test function allows the user to determine if there is an intermittent wiring problem. The test will indicate (by changing the value reading) which parameter moved beyond a predetermined range while wiggling the wiring harness, sensor, or connector.This test requires that the engine is OFF and the key switch is in the ON position (or ECM energized and 0 engine speed). If the engine is started with the wiggle test active, the wiggle test will abort.The Wiggle Test will reduce all ECM requirements to trip fault codes, making the diagnostics sensitive. Under normal operation some fault codes need multiple occurrences before the code will log. But during this test the fault codes will trip the first time.The mechanic wiggles and shakes the wiring to see if codes go active. An audible alarm is also activated if the ECM sees any parameter change state electrically. Once the test has ended, the ECM returns to normal diagnostic state.Calibrations
