The main display module of the Caterpillar Monitoring System is used to show the information that is listed below:

• Machine hours

• Odometer

• Engine speed

• Fuel usage

• Diagnostic codes

An operator mode switch is provided on the dash panel. Momentarily pushing the operator mode switch will allow the operator to scroll through the numeric readout modes that are listed below:

• Service hour meter

• Cumulative odometer

• Digital tachometer

• Diagnostic codes

• Cumulative fuel usage

• Machine hours (Trip)

• Odometer (Trip)

• Fuel usage (Trip)

• Reset of the trip values

Note: The unit indicators are automatically turned ON or OFF in order to correspond with the information that is shown on the numeric display. The values for the "odometer" and the "fuel used" may be displayed in either English units or metric units. Toggling between English and metric units can be performed with the control service tool or the ET.

Trip Values

The trip values are identified by a "t".

• "Trip machine hours"

• "Trip odometer"

• "Trip fuel usage"

If, you push the "operator mode" switch and hold down the "operator mode" switch for 5 seconds the trip values will reset when the Caterpillar Monitoring System is in the "trip values reset" mode. Momentarily pushing the operator mode switch will cause the display to toggle to the next mode without resetting the trip values.

Diagnostic codes

The operator mode switch may be used to view the active diagnostic codes and the logged diagnostic codes. The serv code indicator will be illuminated while active fault codes are displayed. The serv code indicator will be OFF while logged diagnostic codes are displayed. Diagnostic codes can also be displayed through use of the 4C-8195 Control Service Tool or the ET. Clearing any diagnostic codes will require use of one of these service tools.

The service technician can view the machine information that is listed below:

Calibrations

The main display module of the Caterpillar Monitoring System is utilized for the calibration modes of some subsystems. The calibrations that are supported include the systems that are listed below:

• Transmission

• All Wheel Drive

Note: The 4C-8195 Control Service Tool or the ET are required for calibrations.

The Caterpillar Electronic Technician (ET)

Illustration 3	g00777826

The Caterpillar Electronic Technician (ET) is a software program that is used to access data. The service technician can use the Electronic Technician in order to perform maintenance on the machine. Some of the options that are available with the Caterpillar Electronic Technician are listed below:

• Diagnosis of problems

• Viewing diagnostic codes

• Viewing active event codes and logged event codes

• View the status of parameters.

• Clear active diagnostic codes and clear logged diagnostic codes

• Perform calibration of machine systems. See Testing and Adjusting, "Calibrations".

• Program the ECM (Flash). This programming is done with the WinFlash program. See Testing and Adjusting, "Electronic Control Module (ECM) - Flash Program".

• Print reports.

See Troubleshooting, "Using the Caterpillar Electronic Technician to Determine Diagnostic Codes". Diagnostic information is accessed with the following drop-down menus:

• Active diagnostic codes

• Logged diagnostic codes

Event Codes

Some event codes are logged in the ECM memory. Some event codes are active only.

Active Event Codes

Illustration 4	g00849156

An active event indication shall be provided for events that are currently flagged as a system problem. Information for an active event shall include an event identifier (EID) and a text description of the problem.

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

Illustration 5	g00849158

A logged event indicator is provided in order to track the intermittent events or the reoccurring events. The data for the logged event shall include the following information:

• An event identifier (EID)

• A text description of the problem

• The number of occurrences of the problem

• Time stamp that shows the time that the problem first occurred

• Time stamp that shows the time that the problem most recently occurred

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:

• The service technician manually clears the code.

• The code does not reoccur for 1000 hours.

• A new code is logged and there are already ten logged codes in memory. In this case, the oldest logged code is cleared.

List of Event Codes for Power Train ECM

The following table lists the event codes that apply to the implement control system. The recommended response is listed. Use the Cat ET service tool in order to determine the event codes that are active or logged.

Status Groups For The Electronic Technician

ET screen that shows the available groups

The Status groups are lists of machine parameters. The status of the parameters is shown in real time.

The ET will provide the status groups in order to display the information on the parameter status.
