The Caterpillar Electronic Technician (Cat ET)

Illustration 1	g00777826

The Caterpillar Electronic Technician (Cat ET) is a software program that is used to access data. The service technician can use the 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 diagnostic codes. See Troubleshooting, "Using the Caterpillar Electronic Technician to Determine 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.

• 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 service tools.

• 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.

See Troubleshooting, "Diagnostic Code List" for the list of diagnostic codes for the ECM.

• Active diagnostic codes

• Logged diagnostic codes

Event Codes

Logged Event Codes

Typical ET screen for logged events

An indicator for logged events is provided. The indicator allows the service technician to keep track of event codes that are intermittent. The data for the logged event will include the following information:

• An event identifier (EID)

• A text description of the problem

• The number of occurrences of the problem

• A time stamp will display the first occurrence of the problem.

• A time stamp will display the last occurrence of the problem.

Status Groups For The Electronic Technician

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

Configuring Diagnostics

The VIMS 10.3 and later software allow the user to configure the diagnostic operations of the VIMS ECM for the options that are listed below via the (Cat ET):

• Output drivers of the VIMS ECM for lamps, Light emitting diodes and solenoids.

• The preheating of the lamps by the VIMS ECM

Procedure

1. Connect a laptop computer with the (Cat ET) to the service connector of the machine via the communication adapter.

2. Turn the disconnect key and the key start switch to the ON position.

3. Start the (Cat ET) and establish communication with the machine.

Service Operations

The operator and/or the service technician can initiate numerous VIMS service operations.

"OK" Key - This key is used in order to select entries on the Advisor. This key is also used to acknowledge events. Acknowledging an event will remove the event from the display temporarily. Severe events cannot be acknowledged.
