RING 1183995 - Caterpillar

Configuration parameters concern various engine features. Some parameters can affect the performance of the engine. Most of the parameters may be programmed with an Electronic Technician (ET) service tool. Some of the parameters require a password in order to be programmed.Note: For information on programming the parameters, use the appropriate ET service tool and see the Service Manual, "Troubleshooting" module.Some parameters may not be available on all applications. If a parameter is not available the ET service tool will indicate that the parameter is “unavailable” when the parameter is selected. Table 1 is a list of typical configuration parameters.

(1) Jacket water aftercooling or separate circuit aftercoolingThe following parameters are programmed at the factory to “0”:
"Crank Duration"
"Maximum Number Of Crank Cycles"The “0” settings prevent the Electronic Control Module (ECM) from engaging the starting motors. The settings must be reprogrammed before the engine will crank.Ensure that the "Air Shutoff" and the "Ether Control" parameters are "Enabled/ON" (if equipped) . If the engine does not have these options, ensure that these two parameters are "DISABLED/OFF".If the engine is equipped with Prelube, the "Engine Prelube Duration" must be programmed to a value that is greater than “0” seconds. Otherwise, the prelube pump will not cycle. If the engine is not equipped with Prelube, the parameter must be programmed to “0”.The engine has separate circuit aftercooling. The correct configuration of the aftercooling system must be programmed.Engine Serial NumberThe engine serial number should be programmed in order to match the engine serial number that is stamped on the Engine Information Plate.Note: The engine serial number is not programmed on a new ECM.Refer to Troubleshooting for detailed programming instructions.Note: A new ECM date/time clock is programmed so that most of the configuration parameters and monitoring parameters may be reprogrammed. These parameters may be changed from the default setting of the factory in the first 100 hours. These changes may be made without a password. After 100 hours, a password will be required for certain parameters.
