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

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

Here the STEPS;
1). Connect CAT ET Software to diagnostic port on the ECM.

2). Select Service, then Monitoring System menu.

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.

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).

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:
