Useful checks before replacing parts
- Compare pressure unit command, pump relay activity, pressure sensor data, current draw, cycling frequency, and hydraulic temperature.
- Inspect fluid level and condition, pump operation, relay circuit, accumulator or pressure unit leaks, wiring, and connector condition.
- Review whether the fault appears during pressure build, gear selection, actuator movement, or after long idle periods.
