BOSS 8B9725 - Caterpillar

The Electronic Control Module (ECM) provides a comprehensive, programmable engine monitoring system for this engine. The ECM monitors specific engine operating parameters in order to detect abnormal conditions that may develop. The ECM can initiate an action if a specific operating parameter extends beyond an acceptable range. The ECM will react with an action that is dependent on the severity of the condition. The following actions may be initiated by the ECM:
Illumination of a warning lamp or warning alarm
Engine derate
Engine protection shutdownNote: The above actions may not be available for certain parameters or applications.For most applications, Cat® Electronic Technician (ET) can be used to adjust trip points and delay times for the monitoring system parameters. Refer to Troubleshooting , "Event Codes" for specific information that is related to programming these parameters.
