Caterpillar Electronic Technician 2019A + Factory Password Generator 10 Digit

 Caterpillar Electronic Technician (Cat ET) is the factory PC tool for electronically controlled Cat engines — and this package bundles the factory password generator so you're never stuck at the password screen when you need to clear a code or change a protected parameter.

Where it works

Cat on-highway (C7, C11, C13, C15), plus industrial, marine, and gen-set engines with electronic controls.

Why the password generator matters

Some parameter changes and code-clears on Cat engines are locked behind factory passwords. Without them you can read data but can't finish the job. The included generator produces the codes so you can complete the work in your own shop.

What you can do

• Read and clear active and logged diagnostic codes
• Graph live data and run cylinder cut-out tests
• Program parameters and calibrations
• Load injector trim files
• Pull ECM snapshots and configuration reports

Adapter

Cat Communication Adapter 3 or 4 (or a compatible RP1210 device like Nexiq).

Why buy From AutoSofts

Remote install, activation, and same-day support.

This is the 2019A release — proven coverage for older to mid-range Cat engines. Need the latest ECMs? See our 2025A listing.
