3. Previous failures in the engine DIAG3
This screen is connected to the previous screen (DIAG2) as concerns failures involving the hourmeter.
Example:
The screen above shows that the failure code 0032 (electronic regulator rack position detector) occurred at 1200
H and that failure code 0016 (fuel temperature sender) occurred at 1000 H.
A. the number of hours shown indicates the time at which the failures occurred for the first time since the data was re-
initialised.
B. If you wish to erase the failure codes and the number of hours, press the work mode switch for 10 seconds.
C. When data is erased from screens DIAG2 and DIAG3. it is recorded in the electronic control box memory (this data
is only visible using an external computer).
4. Excavator failure detection DIAG4

Example:
The screen above shows a failure in the hydraulic oil temperature sender (0020).
