Diagnostic entry symptoms
Loss of PTO/hitch performance or slow hydraulic functions
Engine power loss under load / aftertreatment derate
IVT/DirectDrive/AutoQuad shift or traction complaint
Measurement and test approach
Log PTO rpm, engine rpm/torque load, SCV flow and system pressure under the same workload; compare pump flow with the model-published L/min reference.
For DPF/SCR complaints, evaluate soot/load, EGT chain, DEF dosing conditions and NOx-sensor behavior together.
Root-cause discrimination
Separate engine power loss from hydraulic overload by comparing engine load with zero hydraulic demand and under high-flow demand.
DTC / SPN / FMI context
Preserve controller identity plus occurrence/freeze-frame data for tractor ECU/TCU/hitch/SCV faults.
Post-repair verification
Repeat scan after PTO load test, high-flow SCV use, hitch lift cycle and road transmission cycle.
Electrical and network
6R 155: Evaluate engine, transmission, hitch/SCV, PTO and ISOBUS/CAN controllers together.
