Part of the John Deere Repair Manuals.
This is the factory TM1576 diagnosis and test manual for the John Deere 8100, 8200, 8300 and 8400 row-crop tractors, 1995-2001. It is the code-reading book: over 140 pages of service code diagnostics covering the ACU, CCU, ECU, HCU, ICU, PCU and SSU controllers, plus CAN bus and wiring checks with full functional schematics and component locations. You get the real test numbers, hydraulic pump pressure at 19500-20800 kPa (2825-3025 psi), SCV port pressure near 3000 psi under load, hitch settling limits, brake pedal travel at 1-3/4 inch (43 mm). Power shift clutch pressure tests, engine compression and oil pressure tests, and GreenStar/AutoTrac diagnostics round it out. This is the diagnosis manual, not the rebuild manual.
