Hey guys, Had this dozer go down due to DEF line blow out. I repaired that line and the code to the low pump pressure cleared out. The other code, CA4769 "AdBlue/DEF level measurement impossible" will not clear. In the service manual for that code it has a notice at the bottom mentioning that this failure code requires "Loaded diagnostics operation to clear failure code". What does that mean? Can anyone help out with this? I tried the 4-123 in the electrical systems abnormality and that cleared everything else but this one since it's still active. Thanks
Gonna have to have Komatsu come out on Monday.
