PROBLEM
The existing software may lead to the operator experiencing active Event Code (E1050-2) High ARD Fuel Pressure, preventing DPF regeneration on certain 950K, and 962K Wheel Loaders.
Previous troubleshooting may have lead technicians to replace the ARD head
prematurely.
If the issue is caused by the software de-bounce threshold, while clearing the active diagnostic code from the ECM allows regeneration to take place, the fault may repeat itself again at the next auto regeneration.
