Cat ®Electronic Technician (Cat ET)
Cat ET can be used by the technician to help perform the following procedures:
- Diagnostic testing
- Calibrations
- Flash programming
- Configuration of the ECM
- Print various reports
Cat ET can display the following information:
- Status parameters
- Diagnostic codes
- ECM settings
- Engine configuration
Always use the latest revision of Cat ET. The media is available on CD and the media can also be downloaded from various Caterpillar web sites.
Once you have downloaded Cat ET onto your PC, you will need a license from your Caterpillar dealer in order to use the software. Various licenses are available for different users with different requirements. Consult your Caterpillar dealer.
Note: For more information regarding the use of Cat ET and PC requirements, refer to the documentation that accompanies your Cat ET software.
Connecting the Communication Adapter
Table 3 lists the standard hardware that is required in order to connect Cat ET.
| Standard Hardware for Connecting with Cat ET | |
|---|---|
| Part Number | Description |
| N/A | Personal Computer (PC) |

| 457-6114 | Cable As (DATALINK CABLE CA3) |
| Tool Operating Manual & Software CD ROM, NETG5057, "Communication Adapter 3" | |
Follow the instructions for the communication adapter. Use the following procedure in order to connect Cat ET and the communication adapter to a PC.
- Remove the electrical power from the ECM.

(3) 317-7485 Communication Adapter
(4) 327-8981 Cable As - Connect cables (2) and (4) to communication adapter (3).
Note: The communication adapter will power up when the adapter is connected to a PC or to an ECM that is powered up.
- Connect cable (2) to the USB port of the PC.
- Connect cable (4) to a service tool connector.
- Restore electrical power to the ECM. Verify that the "POWER" indicator on the communication adapter is illuminated. Make sure that the PC is powered up.
- Establish communication between Cat ET and the ECM. If Cat ET indicates that there is more than one ECM, select the engine ECM.
- If Cat ET and the communication adapter do not communicate with the ECM, refer to Troubleshooting, "Electronic Service Tool Will Not Communicate with ECM".
Refer to Troubleshooting, "Electronic Service Tool Does Not Communicate" if any of the following conditions exist:
- Cat ET displays a message that refers to a communication problem.
- Cat ET displays "Error #142 The interface hardware is not responding".
- Cat ET displays a message that indicates that the firmware in the communications adapter is old.
Communicating with the Wireless Communication Adapter (If so equipped)
A wireless communications adapter can be used in order to allow Cat ET to communicate through a wireless network with the equipment. Both the wireless communications adapter and a communication adapter must be installed on the equipment in order for communication to take place. This allows a technician to access information through Cat ET without being plugged directly into the equipment.
For additional information regarding the setup and operation of the wireless communications adapter, refer to Tool Operating Manual, NEHS1081.
Table 4 lists the optional hardware that is needed in order to connect Cat ET by using a wireless connection.
Note: Some applications cannot use a wireless connection. Also, a dual data link cannot be used with a wireless connection.
Although changes can be made to the internal settings of the 317-7493 Wireless Communication Radio. Caterpillar recommends that the radio is connected to a PC via 317-7496 Computer Cable As (USB)Cable Assembly (8) and 317-7510 Radio Cable Assembly (9).

Use the following procedure in order to connect the wireless communication adapter for use with Cat ET.
- Remove the electrical power from the ECM.
- Ensure that the computer has been correctly configured for the 802.11a or 802.11b/g enabled wireless card. Verify that the PC wireless is installed and working correctly.
- Connect cable (9) between communication radio (8) and the service tool connector.
- Restore the electrical power to the ECM. If Cat ET and the communication radio do not communicate with the ECM, refer to Troubleshooting, "Electronic Service Tool Will Not Communicate with ECM".
- Install 326-9606 Antennas to the 317-7493 Wireless Communication Radio.
PL1000E Communication ECM (If Equipped)
| |
| Illustration 4 | g01163897 |
The PL1000E is an ECM that provides the customer with the ability to integrate Caterpillar engines into specific applications. The PL1000E enables communication from a J1939 data link to a device that utilizes a MODBUS communication protocol. A PC with Cat ET installed can be connected to the PL1000E through the RS232 serial port of the PC. The PL1000E contains an embedded communications adapter that will allow Cat ET to communicate with the engine over the J1939 data link.
Refer to System Operation/Troubleshooting/Test and Adjust, RENR8091, "PL1000E Communication ECM" for additional information.
