How to Setting or Testing the Engine Overspeed using Caterpillar ET Software?

SPN 190 - FMI 0 (Event Codes) - E362 (Engine Overspeed Warning/ Shutdown)

Figure 1.1 - SPN 190 FMI 0 (Murphy PowerView)

Here the STEPS;
1). Connect CAT ET Software to diagnostic port on the Engine. Read More: How to Connecting Caterpillar ET Software to the ECM.

2). Select Service, then Monitoring System menu.
Figure 1.2 - Monitoring System (Service)

3). Just to make sure, before setting up the Monitoring System menu, need to set Unlocked on Monitoring System Configuration Access, through menu Service then Parameter Lockout.
Figure 1.3 - Monitoring System Configuration Access

4). Back to Monitoring System menu, click on Engine Overspeed sub-menu. Change Monitor System window displays, then edit the value on Trip Point (rpm): 1000-2600 (Least Severe - Warning), 1000-2800 (Most Severe - Shutdown).

Figure 1.5 - Change Monitor System (Engine Overspeed)

5). For example: set the Trip Point to 1000 (rpm) for Least Severe (1) - Warning, and set 1100 (rpm) for Most Severe (3) - Shutdown, then try to testing the Engine Overspeed function while engine is running. When the Engine speed reached 1000 (rpm), the Engine Overspeed Warning E362 (1) - SPN 190 FMI 15, will displays as below:
Figure 1.6 - SPN 190 FMI 15 (Murphy PowerView)
Figure 1.7 - Engine Overspeed Warning E362 (1)

And when the Engine speed reached 1100 (rpm), the Engine should be shutdown suddenly (the ECM will activated the Air Shutoff (ASO) Valve or Injection Disabled and Engine Overspeed Shutdown E362 (3) on Status Flags, with Event Code: SPN190 - FMI0, refer to Figure 1.1 above.
