SEAL-O-RING 6E5412 - Caterpillar

Use this procedure if the diagnostic code in Table 1 is active.

Diagnostic Codes Table
Code and Description Conditions which Generate this Code System Response
268-2 Programmed Parameter Fault erratic, intermittent, or incorrect The engine's Electronic Control Module (ECM) detects that one or more of the programmable parameters have not been programmed. The ECM may use a default torque map or the ECM may limit the engine to low idle.
The code is active only. System configuration parameters are parameters that are configured to specify the engine's emissions levels, the power rating, and the specific application. Default values for the parameters are programmed at the factory. Some parameters may be changed in order to equip the engine for a specific application. The system configuration parameters must be reprogrammed if the ECM is replaced. It is not necessary to reprogram the system configuration parameters if you update the ECM flash file. Certain configuration parameters are stamped into the engine information plate.Note: If the parameters that are protected with the factory passwords are changed, the Caterpillar warranty may be voided.268-2 Diagnostic Code
If a programmable parameter has not been programmed, the ECM will generate a 268-2 diagnostic code. The unprogrammed parameters will be set to default. Certain aspects of the engine's performance and engine monitoring may be affected.If "Injector Trim" is displayed below a 268-2 diagnostic code on Cat ET, refer to Troubleshooting, "Injector Trim File - Install".Parameter Descriptions
Equipment ID
This parameter allows the customer to enter a description into the ECM in order to identify the engine's application. A maximum of 17 characters can be entered in the field.Engine Serial Number
The engine serial number must be programmed to match the engine serial number that is stamped on the engine information plate. The engine serial number is not preprogrammed into a replacement ECM.ECM Serial Number
The serial number of the ECM that is stored in the ECM memorySoftware Group Part Number
The part number of the flash file that is currently installed in the ECMSoftware Group Release Date
