How Is ECU Fault Detected in Construction Machinery?
In construction machinery, the ECU or brain is the part that ensures the engine and equipment run properly with data received from various engine sensors and other parts of the vehicle.
Any fault that may occur in a specific part will affect the operation of almost all equipment and functions.
Vehicle ECU Fault
Visual inspection and tests with certain tools and equipment are required to understand a vehicle's ECU fault. In general, the most common symptoms for understanding engine ECU damage are;
Engine ECU Fault on Hitachi Construction Machinery
On Hitachi Construction Machinery the most important symptom is hazard warning lights. If the vehicle fault lamp warns for no reason, ECU fault is possible.
Unstable running, continuous parking problem but the source is not ignition system equipment, feel oxidation, burning appearance or burning smell in the ECU. Compared with the past, high performance loss and low pulling power, interruption of ignition and fuel combustion systems, if damage is seen in the ECU socket the socket tip burns or oxidizes.
If you frequently encounter connection problems and interruptions when connecting a vehicle to an OBD device, sometimes the system runs at normal idle, sometimes it keeps stalling because it cannot maintain idle speed.
If fuel consumption is detected to be illogical and has increased significantly, if the vehicle is vibrating and noisy
The problem may come from the construction machinery engine ECU. However, unless all these problems are checked comprehensively, they should not necessarily be called ECU faults.
These symptoms alone are situations that may cause vehicle owners and
technicians to suspect the ECU that controls the engine.
Why Does the Engine ECU Fail on Construction Machinery?
Reasons for failure of the engine control unit in construction machinery generally include overheating of the ECU due to continuous operation, excessive strain on the construction machine in terms of power, heating or breakage of cables going to the ECU, and external factors. When the vehicle battery is discharged and refilled with another battery, a fault may occur in the vehicle ECU due to different battery voltages and reverse polarity.
How Is a Faulty ECU Repaired?
To understand ECU fault on Hitachi Construction Machinery, control and tests with certain tools and equipment must be performed.
Sold by Nitro Mekatronik, Jaltest Construction Machinery Diagnostic Tool can find and eliminate faults. Also again Nitro Mekatronik produced Ecutest ECU Test Simulator shows exactly what problem exists at which point in the ECU on Hitachi Construction Machinery. Thanks to this, vehicle technicians can easily repair engine ECUs.
