   This article mainly introduces how to solve the walking fault of Doosan DH220-V excavator   Doosan Diagnostic Tool UVIM Support Doosan Excavators High Quality   When the machine is walking in a straight line, the right joystick remains unchanged and the left side  returns to the neutral position (i.e., stops). At this time, the right crawler continues to walk, while the  left crawler slides 800-1000mm before stopping.     1. Checking essentials:   1. After analyzing the hydraulic system, the fault Joints and motors, etc.       02. Measure the system pressure. When the boom is raised to the maximum limit so that the pressure  reaches the maximum, the measured system pressure is 330 BAR, indicating that there is no problem  with the pump.     Doosan Diagnostic Tool DDT G2 SCAN( ECU ,DCU)Software 2016   3. Apply external braking to the walking system. It was also observed that the front pump pressure was  10.5BAR, while the rear pump pressure was 270BAR.       4. After replac

  This article mainly introduces how to deal with the problem that the oil-water separator alarm keeps popping up after the DX215-9C Doosan Construction Machinery model is powered on, the engine accelerates normally, and the buzzer keeps sounding.       2023.07 Doosan DMS-5 Data Monitoring System Diagnostic Software   Inspection Method:       1) Check that the oil-water separator filter element is not clogged, and the fault persists after draining    the water;       2) The fault will disappear intermittently due to vibration during driving;         3) Check the voltage of the water level sensor and find that when there is a fault, the sensor S terminal    0.85YB line has always been an abnormal ground signal. This terminal should be 3.0-3.8V when there    is no water;     Doosan Diagnostic Tool DDT G2 SCAN( ECU ,DCU)Software 2016     4) The fault persists after unplugging the sensor plug, so it is judged that the alarm should be caused by a circuit fault.             Repair res
