Two short jumper wires may be needed to check the continuity of some wiring harness circuits by shorting two adjacent terminals together in a connector. A long extension wire may also be needed to check the continuity of some wiring harness circuits.
Except for harness tests, the use of certain test equipment is not recommended for use on modern Caterpillar electrical circuits. Such testers include the following examples: the 8T-0500 Continuity Tester and 5P-7277 Voltage Tester.

Cat® Electronic Technician (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
- Event codes
- 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.
| Software, JEBD3003, "CATERPILLAR ELECTRONIC TECHNICIAN" |
Once you have downloaded Cat ET onto your PC, you will need a license from your Caterpillar dealer 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 program software.
Connecting the Communication Adapter
Table 4 lists the standard hardware that is required to connect Cat ET.
Note: The 275-5120 Communication Adapter Gp was canceled and replaced by the 466-6258 Communication Adapter Gp. However, the 275-5120 Communication Adapter Gp can still be used.
| Standard Hardware for Connecting with Cat ET | |
|---|---|
| Part Number | Description |
| N/A | Personal Computer (PC) |
| 317-7484 | Communication Adapter Gp |
| Components of the 466-6258 Communication Adapter Gp | |

| Tool Operating Manual & Software CD ROM, NETG5057, "Communication Adapter 3" | |
Follow the instructions for the communication adapter. Use the following procedure to connect Cat ET and the communication adapter to a PC.
- Remove the electrical power from the ECM.

(2) Cable As (USB)
(3) Communication Adapter (3)
(4) Cable As (DATA LINK) - 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.
Dual Data Link Communications (If so equipped)
When the connection of the communication adapter is complete, observe the communication adapter and Cat ET. Certain applications require that dual data link communications be established to perform various test procedures. These tests will be listed in the "Diagnostic Tests" menu, some tests may not be available (grayed out). If there are diagnostic tests that are unavailable in Cat ET, ensure that your service tool is communicating in dual data link mode.
Use the following indicators to confirm that Cat ET is communicating on dual data links:
- "J1939" indicator is flashing
- "Cat Data Link" indicator is flashing
- Cat ET is not displaying "Service tool support is limited"
Refer to Troubleshooting, "Electronic Service Tool Does Not Communicate" if the "J1939" indicator and the "Cat Data Link" indicator are not flashing. Both indicators will be flashing during dual data link communications with the ECM.
