The Cat® Electronic Technician (Cat ET) service tool is a software program that is used to access machine data. Use Cat ET when performing machine maintenance. Some Cat ET options are:
- View diagnostic trouble codes (DTCs) (See Troubleshooting, "Using Caterpillar Electronic Technician to Determine Diagnostic Codes")
- View active and logged event codes
- View parameter status
- Clear active and logged DTCs
- Perform calibrations
- Flash electronic control modules (ECMs) (This process is done with the WINflash program.
- Print reports
Following are some service tool functions:
- Display ECM system failures
- Display input and output status
- Display ECM settings
- Display input and output parameters status in real time
- Display internal diagnostic clock hour
- Display number of occurrences and the clock hour of the first and last occurrence for each logged DTC
- Display logged DTC and event definitions
- Load new flash software
See Troubleshooting, "Diagnostic Code List" for a list of diagnostic codes.
Logged Event Codes
An indicator for logged events is provided and allows tracking of intermittent event codes. The logged event data includes:
- Event Identifier (EID)
- Problem description
- Number of problem occurrences
- Time stamp will display the problem first occurrence
- Time stamp will display the problem last occurrence
The status groups are lists of machine parameters and are shown in real time.
