ROD AS-PISTON 7J3338 - Caterpillar

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

Diagnostic Codes Table    
Code    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 affect the emissions and the power of the engine. Default values for the parameters are programmed at the factory.The Caterpillar Electronic Technician (ET) can be used to view certain parameters that can affect the operation of the engine. Cat ET can also be used to change certain parameters. There may be certain parameters that cannot be changed and there are some applications that do not allow any changes to the programmable monitoring system. The parameters are stored in the ECM. Some of the parameters are protected from unauthorized changes by passwords. Parameters that can be changed have a tattletale number. The tattletale number shows if a parameter has been changed.Check Programmable Parameters (268-2)
If a programmable parameter has not been programmed, the ECM will generate a 268-2 Check Programmable Parameters diagnostic code. The programmable parameter that is not programmed will be listed under the 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 Caterpillar Electronic Technician (ET), refer to Troubleshooting, "Injector Trim File - Install".Parameter Descriptions
"Equipment ID"
"Equipment ID" allows the customer to enter a description into the ECM in order to identify the machine. A maximum of 17 characters may be entered in the field. This parameter is only for reference by the customer. This parameter is not required."Engine Serial Number"
Program the "Engine Serial Number" to match the engine serial number that is stamped on the engine information plate. If the ECM is replaced, the engine serial number from the engine information plate must be programmed into the new ECM.Note: When you are requesting factory passwords, always use the engine serial number that is programmed in the ECM."Rating Number"
The "Rating Number" corresponds to the selected set of performance maps for the application. This selected set of performance maps comes out of several unique sets of maps that are resident in the flash file."Top Engine Limit" (TEL)
Illustration 1 g01750573
"TEL" is a parameter that defines the maximum allowable engine speed for maximum power. "TEL" can be programmed up to the maximum rated engine speed. "TEL" is defined along the engine's lug curve."Engine Accel. Rate"
"Engine Accel. Rate" determines the rate of change of the engine speed (acceleration or deceleration) during PTO operation. This rate of change is also used to achieve intermediate engine speed."FLS" (Full Load Setting)
"FLS" is a number that represents the adjustment to the fuel system that was made at the factory in
