Parameters that are customer programmable are those parameters that affect the engine speed limits, the power rating within an engine family and the PTO operation. Refer to Troubleshooting, “System Configuration Parameters” for more detail on parameters that are customer programmable. Factory passwords are required to perform each of the following functions: Program a new Electronic Control Module (ECM). When an ECM is replaced, the system configuration parameters must be programmed into the new ECM.
A new ECM will allow these parameters to be programmed once without factory passwords. After the initial programming, some parameters are protected by factory passwords. Use the Caterpillar Electronic Technician (ET) to change parameters that are customer programmable. To obtain customer passwords, contact the owner of the engine. If the owner has lost the owner’s passwords, customer passwords may be read by using Cat ET. Clear event codes.
