Cat ET On & Off Road Software

Caterpillar® Electronic Technician (Cat ET) is the OEM diagnostic software used to service electronically controlled Cat engines and machinery for both on- and off-road applications. It allows technicians to connect to ECMs to diagnose issues, perform calibrations, and analyze performance data.

Jaltest Commercial Vehicle and Off-Highway software offers full dealer-level coverage of Cat ET—including the ability to clear and reset Stage 3 DPF soot levels without requiring an encryption code. Jaltest eliminates the need to purchase, manage, and train on multiple OEM software systems.
