Use this section for the troubleshooting of problems that have generated event codes but do not have active diagnostic codes. When the event code is generated, the event is active. Any generated code becomes logged in the permanent memory of the Electronic Control Module (ECM).
Event codes alert the operator that an abnormal engine operating condition such as low oil pressure or high coolant temperature has been detected. Events do not indicate problems with the electronic system. Event codes also indicate the nature of the problem. Event codes may be viewed on a personal computer that has the software for the AVSpare Electronic Technician (ET).

Typical example |
Illustration 1 indicates output voltage from the coolant temperature sensor. When the output signal from the sensor is between 4.2 volts and 4.8 volts, an event code will be generated for above normal coolant temperature.
You can program the engine to perform the following actions for some applications:
- Engine warning
- Engine derate
- Engine shutdown
Cat ET can be used to turn the display of these features on and off. When the features are turned on, the display will appear on an electronic monitoring module and an event will also be logged in the ECM. When the features are turned off, the display will not appear on a monitoring module, but an event will still be logged.
