Part of the John Deere Repair Manuals.
This is the John Deere factory diagnostic manual (TM2197) for the 5225, 5325, 5425, 5525, 5603 and 5625 utility tractors, published August 2010. Across 1,889 pages it covers every diagnostic trouble code logged by the CCU, HCU and PTR electronic control units, symptom-based diagnostic trees for all major systems, and step-by-step tests and adjustments for the engine, electrical circuits, SyncShuttle and PowerReverser transmissions, drive systems, steering, brakes, hydraulics and operator station. Full functional schematics and connector pinout diagrams for both cab and open-station configurations are included - the same information a John Deere dealer technician uses to trace an intermittent fault from the first DTC to the confirmed root cause.

John Deere 5225-5625 Common Problems This Manual Covers
PowerReverser commands neutral unexpectedly or refuses a direction change during operation
Start with the PTR DTC chapter and read the active fault code. Most cases are a sensor reference voltage fault (PTR 001079.03/04) or a solenoid circuit voltage fault triggering the fail-safe neutral command. The PTR Tests and Adjustments chapter covers enable pressure sensor circuit tests and solenoid resistance checks so you can confirm whether the fault is in the wiring, the solenoid itself or the PTR controller before any disassembly.
Manual Section: Diagnostic Trouble Codes - PTRHydraulic system pressure is low or the rear hitch lifts slowly under load
Run the pump flow test from Section 270 first: connect the JT07148 Digital Hydraulic Tester, set engine speed to 2000 rpm and load to 10 345 kPa (1500 psi). If flow is below 39.3 Lpm on a 5225/5325 or below 53.5 Lpm on a 5425/5525, the pump is worn or the filter is clogged. Then run the main relief valve test to confirm outlet pressure is between 18 995 and 19 685 kPa. Address the lowest reading first before condemning larger components.
Manual Section: Hydraulics - Tests and AdjustmentsIntermittent starting failure or no-crank condition with no obvious blown fuse
Follow the Seven-Step Electrical Test Procedure in Section 210 and use the Starting and Charging System Diagnosis group in Section 213. Check fuses F1, F18 and the F26 fusible link in the Vehicle Electrical Center first, then test the ELX relay, neutral start relay and key switch circuit. The functional schematic SE1 in Section 240 shows the full starting circuit so you can pinpoint the open or shorted leg with a digital multimeter without chasing individual wires blind.
Manual Section: Electrical - Tests and AdjustmentsCCU fault code after replacing a controller, or VIN security fault preventing normal operation
A VIN security fault occurs when a replacement CCU, HCU or PTR from another tractor is installed without reprogramming. The Control Units section explains how to check VIN Network addresses at CCU address 251, HCU address 251 and PTR address 251 to confirm they all match the tractor's vehicle identification number. If they do not match, program the new controller per Reference 245-05-005 before returning the machine to service.
Manual Section: Control Units - CCUFrequently Asked Questions
How do I read and diagnose a DTC on the John Deere 5425 or 5525?
The manual's Diagnostic Trouble Code section (Section 211) lists every CCU, HCU and PTR fault code with its trigger condition and a step-by-step diagnostic tree. Find the code on the display, look it up in the appropriate control unit chapter, and follow the numbered action steps to isolate the failed circuit or component before ordering parts.
Why does the PowerReverser transmission command neutral unexpectedly on a 5525 or 5625?
Most unintended neutral commands trace to a DTC in the PTR controller caused by a solenoid circuit fault, sensor voltage out of range, or a failed enable pressure sensor. The PTR Code Diagnostics chapter and the PowerReverser Tests and Adjustments section walk through checking solenoid resistance, enable pressure, and clutch calibration values so you can confirm the root cause before pulling the transmission.
What hydraulic pump flow and relief pressure should I see when testing the 5225 or 5325?
At 10 345 kPa (1500 psi) load and 2000 rpm, a healthy 5225 or 5325 pump should deliver 39.3-51.2 Lpm (10.4-13.5 gpm). Main relief valve outlet pressure should read 18 995-19 685 kPa (2,755-2,855 psi). The Hydraulics Tests section covers the full procedure including gauge connections and the JT05473 test kit setup.
Does this manual cover the electrical wiring for both cab and open-station 5000 series tractors?
Yes. Section 240 includes full functional schematics and separate connector information chapters for 5225, 5325, 5425, 5525 and 5625 cab/open-station tractors (Group 30) and for the 5603 model (Group 35). The seven-step electrical test procedure and schematic symbol guide in Section 210 give you the method to work through any intermittent circuit fault.
How do I test the MFWD and rear PTO systems on these tractors?
The System Diagnosis section (Section 213) covers MFWD and rear PTO as separate diagnostic groups. The MFWD chapter has both SyncShuttle and PowerReverser transmission variants and walks through clutch engagement checks, solenoid tests and the drive system schematics. The PTO chapter covers the safety interlock, solenoid circuit and control unit outputs so you can differentiate an electrical fault from a mechanical one.
