Table 1
Minimum Maximum Default
−63.5 +63.5 0 "Calculating Fuel Correction Factor"
The following formula should be used to determine the new FCF.
Illustration 1 g00629908OLD FCF - Fuel correction factor in ECMTANK - Actual fuel economyECM - Fuel economy in ECM stored trip dataRefer to Illustration 2 as an example. The actual tank fuel economy is 7.1 mpg. The fuel economy in the ECM stored trip data is 7.0 mpg over the same distance with an old FCF of −2.5.
Illustration 2 g00629939"Dash - Change Fuel Correction Factor"
This parameter allows the driver to adjust the "Fuel Correction Factor". An owner/operator would want the driver to be able to change this information, but a fleet operation might not want the driver to be able to change this information.
Table 2
Alternative Default
"Yes" "No" "Dash - PM 1 Reset"
This parameter determines the driver's access for resetting the PM 1 (maintenance) after the PM 1 has been performed. The maintenance indicator mode cannot be programmed to "Off" for the "PM 1 Reset" parameter to take effect.
Table 3
Alternative Default
"Yes" "No" "Dash - Fleet Trip Reset"
This parameter determines the driver's access for resetting the fleet trip segment.
Table 4
Alternative Default
"Yes" "No" "Dash - State Selection"
Program this parameter to NO to disable this function of Messenger. Messenger will not show "State Selection" as an option to the driver. If this parameter is programmed to "YES" (default), Messenger will provide the feature of "State Selection".Programming this parameter to "NO" eliminates "State Selection". Therefore, the storage of the trip data ("State Selection") is eliminated.
Table 5
Alternative Default
"No" "Yes" "Theft Deterrent System Control"
When this parameter is used with a "Theft Deterrent Password", this parameter prevents the engine from starting unless the password has been entered via the dash display of Messenger. Before the operator can use the feature of theft deterrent of Messenger, the system must be turned on. In order to turn on the theft deterrent, the Caterpillar Electronic Technician (ET) must be used to program the parameter for the theft deterrent to "Yes". The operator must first enter the password before the engine is shut off. This will enable the system. Enabling the system prevents the engine from starting without re-entering the password on the next attempted start.Note: After the "Theft Deterrent System Control" parameter is set to "Auto-Enabled", the "Theft Deterrent Password" is the password that is required to restart the engine.
Table 6
Alternative Default
"Yes"
"Auto-Enable" "No" "Theft Deterrent Password"
The "Theft Deterrent Password" is the password that is required by the ECM before the feature of theft deterrent is enabled. After the theft deterrent is enabled, the "Theft Deterrent Password" is the password that is required to restart the engine. All of the characters must be in the upper case.
Table 7
Alternative Default
Four Characters
A through Z
0 through 9 0000 "Quick Stop Rate"
This parameter determines the rate of vehicle speed change that is used by the ECM to record a quick stop event code and a quick stop snapshot. Programming this parameter to zero will disable this feature and no quick stop events will be logged. Each quick stop snapshot contains 60 frames of information. The no. 45 frame is the quick stop event. The quick stop snapshot also contains 44 frames before the quick stop event and 15 frames after the quick stop event. Each frame is separated by 1.0 second.
