Cat Monitoring System Display Components (1) Indicator lamps (2) Quad gauge module (3) Speedometer (4) Tachometer (5) Air pressure gaugesThe warning indicators for the subsystem on the Instrument Cluster will illuminate when an EID is activated for a particular subsystem. When level 1 events are active, the warning indicator of the subsystem will be the only type of indicator that will illuminate.The action Indicator will flash red when a level 2 warning or level 3 warning is active. If communication between Messenger and the Instrument Cluster fails, the action lamp will flash yellow.The action alarm is driven as an output directly from the Instrument Cluster. If a level 3 warning is active, the action alarm will sound a tone (pulsing). The action alarm will sound these tones in order to alert the machine operator that immediate action is required.If two warnings of a different level are active at the same time, the highest level warning will be displayed.The response of the Messenger to these warning levels is shown in the following table.

When an abnormal operating condition of the implement system occurs, the status screen on the Cat Electronic Technician (ET) indicates that there is an active event.Event codes are displayed on Cat ET in the following format:EXXXX Description of the codeThe "E" means that the code is an event code. The "XXXX" is a numeric identifier. The numeric identifier is followed by a description of the code. Active event codes are listed in ascending numerical order. The code with the lowest number is listed first. The active event code is removed from the list when the condition is no longer present.Logged Event Codes
Some event codes are logged in the ECM memory. Some event codes are active only. The logged event codes are listed in chronological order. The most recent code is listed first.A logged code is cleared from memory when one of the following conditions occur:
