Components that are needed for the Caterpillar Electronic Technician (Cat ET)

The Caterpillar Electronic Technician (Cat ET) is a software program that is used to access, view, monitor and sometimes change the data that a particular ECM is using to control a machine system. The service technician can use the Cat ET in order to perform maintenance on the machine. Some of the options that are available with the Caterpillar Electronic Technician are listed below:

• View the active diagnostic codes and logged diagnostic codes. See Troubleshooting, "Using the Caterpillar Electronic Technician to Determine Diagnostic Codes".

• Viewing the active event codes and logged event codes

• View the status of parameters.

• Clear active diagnostic codes and clear logged diagnostic codes

• Perform calibrations of machine systems.

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

• Print reports.

The following list contains some of the diagnostic functions and programming functions that are performed by the Cat ET service tool.

• The failures of the ECM system are displayed.

• The status of most of the inputs and the outputs are displayed.

• The settings for the ECM are displayed.

• Display the status of the input and output parameters in real time.

• Display the clock hour of the internal diagnostic clock.

• The number of occurrences and the clock hour of the first occurrence and the last occurrence is displayed for each logged diagnostic code.

• The definition for each logged diagnostic code and each event is displayed.

• Load new FLASH software.

• Active diagnostic codes

• Logged diagnostic codes

See Troubleshooting, "Diagnostic Code List" for the list of diagnostic codes that can be activated by all of the power train control modules.

Diagnostics

Active Diagnostics

Typical Cat ET screen for active diagnostics.

A screen for active diagnostics is provided. This screen allows the service technician to identify any diagnostic codes that are currently active on the machine. The data for the active diagnostics will include:

• A Component Identifier (CID).

• A Failure Mode Indicator (FMI).

• A text description of the problem.

Diagnostics

Logged Diagnostics

A screen for logged diagnostics is provided. This screen allows the service technician to keep track of diagnostic codes that are intermittent. The data for the logged diagnostics will include:

• A Component Identifier (CID).

• A Failure Mode Indicator (FMI).

• A text description of the problem.

• The machine hours of the first occurrence of the diagnostic.

• The machine hours of the last occurrence of the diagnostic.

Events

Active Events

A screen for active events is provided. This screen allows the service technician to identify any event codes that are currently active on the machine. The data for the active events will include:

• An Event identifier (EID).

• A Warning Level.

• A text description of the problem.

Event Codes

Logged Event Codes

A screen for logged events is provided. This screen allows the service technician to track event codes that are intermittent. The data for the logged events will include:

• An event identifier (EID).

• A Warning Level.

• A text description of the problem.

• The machine hours of the first occurrence of the diagnostic.

• The machine hours of the last occurrence of the diagnostic.

Status Groups For The Electronic Technician

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