John Deere Service Advisor 5.4Offline AG + CF Last one

John Deere Service Advisor 5.4 (Offline, AG & CF) is the full dealer diagnostic and repair-information suite — running completely offline, with no live subscription needed.

What it covers

Both John Deere lines: Agriculture (tractors, combines, sprayers, balers) and Construction & Forestry (excavators, loaders, dozers, skidders).

More than a code reader

Service Advisor pairs diagnostics with Deere's full technical library, so you get the repair steps too:

• Read and clear diagnostic trouble codes
• Live readings, tests, and calibrations
• ECU programming and controller setup
• Injector and sensor calibrations
• Step-by-step diagnostics plus operator, diagnostic, and technical manuals and wiring diagrams

Adapter

The John Deere EDL (Electronic Data Link) v2 or v3. Good news: 5.4 also works with a Nexiq USB-Link 3, so if you already own one you're set.

Heads up on space

This is a big database — plan on roughly 400GB free before install. We'll walk you through it.
