Maintenance Parameters
Maintenance Indicator Mode
Description:
The Maintenance Indicator will send a signal via the
datalink to either a service tool, optional Cat ID or
Cat Messenger, some OEM installed electronic dash
displays or the Fleet Information Software program
indicating that maintenance will be due in 3,000 miles
or less. This allows for the convenient scheduling of
service.
The preferred way for the ECM to calculate when the
next preventive maintenance (PM) is due is to compare
the actual amount of fuel used by the engine, to the
engine oil capacity. (This method is based on the fact
that engine oil additives will become depleted over time
based on the amount of fuel burned and oil capacity)
The customer has the option of setting a specifi c hour
or mileage (km) Preventive Maintenance (PM) Interval.
This is done by programming the Maintenance Indicator
Mode to one of four options:
Manual - Distance – Fixed number of Miles (km)
Manual - Hours – Fixed number of Hours
Automatic - Distance – ECM Calculated Miles (km)
Automatic - Hours – ECM Calculated Hours
If either Manual mode is selected, the PM1 Interval (see
page ) parameter must be programmed to the desired
distance or hours. If either Automatic mode is selected,
the Engine Oil Capacity (see page ) parameter must
be programmed to the oil capacity.
