Part of the John Deere Repair Manuals.
This is the complete John Deere factory Diagnosis and Tests Service Manual (TM400719) for the 6230, 6330, 6430, 7130 and 7230 tractors sold in North America, covering machines built from the 2009 serial number break onward. All 3,315 pages are organized around what a shop technician actually needs: how to read and clear BCU, ECU, EPC and PRC control unit fault codes, how to trace observable symptoms through the transmission and hydraulic system, how to run the engine operational checks and fuel/cooling tests, and how to use the full wiring diagrams in Section 240 to chase an intermittent electrical fault to its source. This is the same document a John Deere dealer technician opens at the workstation when a machine comes in with a code on the CommandCenter display.
