The Electronic Control Module (ECM) monitors the operating parameters of the engine. The ECM will generate an event code if a specific engine parameter exceeds an acceptable range that is defined by the engine monitoring system. For information on event codes, refer to Troubleshooting, "Event Codes" for a list of the applicable event codes for this application.
The ECM can initiate responses if a specific engine parameter exceeds an acceptable range.
Refer to Table 1 for the available responses for this engine.
| Cross-reference for System Response to an Event Warning Category Indicators (1) and (3) | ||
|---|---|---|
| Warning Category Indicator | System Response Shown on Cat ET | Description of the System Response |
| (1) | "Least Severe" | Warning |
| (2) | "Moderate Severe" | Impending Shutdown |
| (3) | "Most Severe" | Shutdown |
Note: All severity levels may not be supported for a monitored parameters.
Use Cat® Electronic Technician (ET) to perform the following activities for the monitoring system:
- Viewing parameters
- Parameter programming
- Set delay times
The default settings for the parameters are programmed at the factory. To accommodate unique applications and sites, some of the parameters may be reprogrammed with Cat ET. Use Cat ET to modify the monitoring system parameters.
Note: Some parameters require no password to be changed. Other parameters can be changed with customer passwords. Some of the parameters are protected by factory passwords. There are some parameters that cannot be changed. Some applications do not allow any changes to the programmable monitoring system. Parameters that are protected by factory passwords can only be changed by dealer personnel.
Viewing or Changing the Settings of the Monitoring System
Use the following procedure to view the parameter settings and/or change the parameter settings:
- Select the "Service/Monitoring System" screen on Cat ET.
Note: Ensure that you select the correct ECM for the parameters that are being changed before continuing.
- Highlight the desired parameter. Then click the "Change" button in the lower left corner of the screen.
The "Change Monitor System" screen will appear.
- Change the "State" of the parameter.
- Set the "Trip Point" and the "Delay Time" according to the "Allowed Values" that are displayed in the lower half of the screen.
- Click the "OK" button.
If a password is required, the "Enter Passwords" screen will appear. Enter the correct passwords and then click the "OK" button.
If a factory password is required, the "Enter Factory Passwords" screen will appear. Refer to Troubleshooting, "Factory Passwords" for information that is related to obtaining factory passwords.
The new settings will be effective immediately.
Note: Factory passwords are only available to service technicians from an authorized Caterpillar Dealership. Customers of Caterpillar do not have access to the Caterpillar Factory Password System (FPS).
Note: Refer to Troubleshooting , "Engine Monitoring System" for the descriptions and available settings for the parameters.
