Diesel Particulate Filter Monitor System Caterpillar

Events

The events are used in order to record a problem that is detected by the control system. Events are also used to document adverse engine operation. Events will be communicated to the service tool via the CDL. An event indicates that the control system has detected an engine problem. An event does not indicate an electronic problem. For example, the high exhaust temperature event is disabled if a problem with the temperature sensor is detected. (Events can be configured to be triggered on a diagnostic.)

An event is identified by a numerical code. The EID (Event Identifier) identifies an engine problem or a problem with the machine. The service tool is used to display the EID. The service tool adds descriptive text for each EID in order to avoid mistakes in interpreting the codes.

Logged Events

When an event is activated, information about the event is logged into permanent memory for the Electronic Control Module. The CDL can then request this information from the ECM. The CDL will display the following information for each logged event. Up to twenty five different events can be logged. Events are not automatically erased.

• EID

• FMI

• Description of the event

• Number of occurrences

• The first time of occurrence

• The last time of occurrence

Events may be cleared from the memory of the ECM in order to use the CDL. Logged events can be configured so that a factory password is required to clear the event. Table 1 references the Event Codes that can be seen in order to use the Diesel Particulate Filter Monitor System.
