John Deere 5085E and 5100E FT4 Tractors Diagnostic Technical Manual (TM134419)

On an FT4 5085E or 5100E, a lot of problems turn out to be electrical or controller related. TM134419 is the book John Deere wrote to trace them, with codes, schematics and tests for every circuit. If you're tired of throwing parts at a warning light, this is the manual that tells you exactly where to put the meter.

John Deere 5085E and 5100E Final Tier 4 (FT4) tractors. Manual dated 16FEB15.

What this manual covers

Trouble codes are grouped by controller: CCU (chassis), ECU (engine), EIC (engine interface), ICC (instrument cluster) and PTR (power train reverser). An observable-symptoms section links what you notice in the field back to the likely codes and systems. Each electrical circuit, from the key switch and starter to tail lights, wipers, air seat, loader lights, backup alarm and mid-mount SCV, has its own schematic, connector information and test. Drive systems and transmission, steering and brakes, hydraulics, and the cab or open station get the same treatment: calibrations, theory, schematics and tests.

Check before you buy

Diagnostic manual only; repair and teardown are in a separate repair manual. Make sure your tractor is the FT4 version, since earlier 5085E and 5100E builds use different documents.
