Note: If the parameters that are protected with the factory passwords are changed, the Caterpillar warranty may be voided.
Engine Serial Number
The engine serial number should be programmed to match the engine information plate. The serial number is not programmed on a new ECM.
FRC Offset Value
The ECM determines a value that is based on the atmospheric pressure. The value is used to adjust the fuel ratio control. This will control the exhaust while the engine accelerates. An offset value of ± 25 may be used to adjust for customer preference, fuel quality or other factors that affect engine performance.
Note: This parameter may not be available on all applications.
Rated Fuel Position
This parameter is used to set engine power. A Factory Password is required to change this setting.
Minimum     | Default     | Maximum     |
Minimum Rack     | Engine Dependent     | Engine Dependent     |
Low Idle
The parameter defines the lowest rpm level.
Minimum     | Default     | Maximum     |
810 rpm     | 900 rpm     | 1450 rpm     |
Cooldown Speed
This parameter defines the engine rpm level when the ECS is placed in the STOP position.
Minimum     | Default     | Maximum     |
810 rpm     | 810 rpm     | 1800 rpm     |
Cooldown Period
This parameter defines engine operation at the cooldown speed. Programming this parameter to 0 will disable this function.
Minimum     | Default     | Maximum     |
0 minutes     | 0 minutes     | 30 minutes     |
Prelube Time
The parameter sets the amount of time for prelubrication. Programming this parameter to 0 will disable this function.
Minimum     | Default     | Maximum     |
0 seconds     | 0 seconds     | 210 seconds     |
Crank Duration
The crank duration determines when the starting motors will be energized. The crank duration determines when the starting motors will be disengaged. Programming this parameter to 0 will prevent the ECM from engaging the starting motors.
Minimum     | Default     | Maximum     |
0 seconds     | 0 seconds     | 60 seconds     |
Cranking Cycles
This parameter is the total number of crank cycles that can be performed.
Minimum     | Default     | Maximum     |
0     | 0     | 10     |
Crank Terminate Speed
This parameter determines when the starting motor will disengage.
Minimum     | Default     | Maximum     |
100 rpm     | 400 rpm     | 500 rpm     |
Air Shutoff
Programming the parameter to "OFF" will disable the air shutoff. This parameter should be programmed to "OFF" if the function is not being used or installed on this engine. This will prevent diagnostics from being logged.
Note: This parameter can only be read from the secondary ECM.
Minimum     | Default     | Maximum     |
DISABLED     | ENABLED     | ENABLED     |
