Fault Logging
i02512380
SMCS Code: 1000; 1900; 1901; 1902
The system provides the capability of Fault Logging.
When the Electronic Control Module (ECM)
generates an active diagnostic code, the code will be
logged in the memory of the ECM. The codes that
have been logged in the memory of the ECM can
be retrieved with Caterpillar electronic service tools.
The codes that have been logged can be cleared
with Caterpillar electronic service tools. The codes
that have been logged in the memory of the ECM
will be automatically cleared from the memory after
100 hours. The following faults can not be cleared
from the memory of the ECM without using a factory
password: overspeed, low engine oil pressure, and
high engine coolant temperature.
