INDICATOR-DIAL 6V3075 - Caterpillar

The Electronic Control Module (ECM) monitors the operating parameters of the engine. If a specific engine parameter exceeds an acceptable range that is defined by the engine monitoring system, the ECM will generate a diagnostic code. For information on diagnostic codes, refer to Troubleshooting, "Diagnostic Trouble Codes" for a list of the applicable diagnostic codes for this application.Three possible responses may be available for each parameter. Some of the responses are not available for some of the parameters. Refer to Table 1.

(1) Least Severe
(2) Moderate Severity
(3) Most Severe Use an electronic service tool to view the current settings for the monitoring system parameters. The electronic service tool is also used to reprogram parameter settings and 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 the electronic service tool.Note: Some parameters require no password in order 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 may not 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.Refer to Systems Operation Section, "Engine Monitoring Parameters" for information that is related to changing the parameters for the engine monitoring system.
