Cat® Electronic Technician (ET) Service Features
There are many automatic test procedures and system overrides available within Cat ET. These procedures may assist with a troubleshooting procedure or be used to validate a repair.Found under "Diagnostics/Diagnostic Tests/Override Parameters", the following overrides can be found:Diagnostic Lamp Override

Cylinder Cutout Test
This test can disable individual cylinders to when the engine is running to help identify cylinders that are performing below the required level.Click "Change" for an individual cylinder to switch off that cylinder manually. The cylinder will be automatically re-energized 10 seconds after the cylinder has been switched off. Wait a further 10 seconds before disabling the next cylinder.This test can be used to identify faults by listening to the sound of the engine as a cylinder is disabled. If there is no change in the sound of the engine as a cylinder is disabled, there may be a fault in that cylinder.Wiggle Test
The Wiggle Test function in Cat ET can aid in diagnosing intermittent electrical faults in Electronic Control Systems. The Wiggle Test function allows the user to determine if there is an intermittent wiring problem by indicating (by changing the value reading) which parameter on the screen has moved beyond a predetermined range while "wiggling" the wiring harness, sensor, connector, etc.Rail Pressure Test
This test raises the fuel pressure in the high-pressure fuel rail to 180000 kPa (26107 psi) for 1 minute at 1300 rpm.After this test has been run, allow the fuel pressure to drop to a safe level. The fuel system can then be inspected for signs of leakage.Run Up Test
The Run Up Test is a dynamic cutout test that determines the performance capability of an individual cylinder by conducting a series of acceleration and deceleration cycles. The Run Up Test will perform 7 acceleration cycles, one as a baseline with all cylinders firing and 6 additional runs with each run cutting out 1 cylinder at a time for each. The ECM will monitor engine speed and acceleration rates to determine the performance capability of the cut-out cylinder.Compression Test
The Compression Test is conducted during cranking and fuel quantity is set to zero. The instant angular speed of the engine is measured at fixed crankshaft positions corresponding to compression and expansion phases of each cylinder. Speed deviations give an indication about differences in leakages and compression values of the concerned cylinder.
