CAT ET3 Diagnostic Interface

This listing offers an ET3-style communication interface for selected Caterpillar diagnostic applications. It provides a data link between supported equipment and a compatible computer/software setup. Confirm whether the supplied hardware is a genuine Caterpillar Communication Adapter or an aftermarket interface.

Support and Applications

• Selected Caterpillar engine applications covered by the chosen Cat ET release.
• Supported construction or industrial equipment with a compatible diagnostic network and correct cables.
• Compatible Windows computer, adapter driver and appropriately licensed diagnostic software.

Diagnostic Functions and Software

Fault-code information, status parameters, supported tests and service functions depend on the equipment and software. This interface alone does not supply calibration files, factory passwords, programming permissions or an online account. Generic OBD2 car-scanner compatibility is not established by the connector wording.

Before Ordering

Provide the machine model, serial number, engine identification and diagnostic socket photo. Confirm cable ends, power requirements, software release and licence scope. A laptop and manufacturer subscriptions are separate unless specifically quoted.
