Doosan DL420 Wheel Loader ECU Software Solutions
The Doosan DL420 is Doosan's wheel loader. The engine control unit (ECU) software is recalibrated on the machine's own original file; the original software is backed up.
Doosan DL420 DPF and EGR fault solution
Loaders shuttle back and forth over short distances; the particulate filter (DPF) often fails to reach regeneration temperature and blocks. With an EGR fault or a NOx sensor fault in the AdBlue (SCR) system the machine enters limp mode and loading stops at the quarry or plant. The cause is diagnosed first; the software solution is applied according to the ECU type.
