Factory Passwords
Factory Level Security Passwords are required to clear certain logged events or change certain parameters. These changes are restricted to authorized personnel. When the correct passwords have been entered, the changes will then be allowed to be programmed into the ECM.The Electronic Service Tool Factory Passwords Screen will display ECM Serial Number, Engine Serial Number, Electronic Service Tool Serial Number, a Reason Code, and Total Tattletales. This information must be given to an authorized Caterpillar dealer to obtain the proper passwords. The passwords are controlled by Caterpillar Inc. and may only be obtained by an authorized Caterpillar dealer. Examples of the Electronic Service Tool Screens are shown in this section. The passwords are only good for one programming or clearing session. A different set of passwords will be required if the Electronic Service Tool Screen is exited before clearing ALL events or programming ALL parameters.Electronic Technician (ET)
For details on how to read and change parameters using ET, Communication Adapter Tool and the appropriate software, refer to the instructions included with the JERD2129 or JERD2142 ET Data Subscription and the JERD2124 ET Software.Electronic Control Analyzer Programmer (ECAP)
For details on how to read and change parameters using ECAP, Communication Adapter Tool and the appropriate Service Program Module, refer to Tool Operating Manual SEHS9343, Using The ECAP NEXG4521 Machine Functions Service Program Module and Special Instruction SEHS9264. The ECAP may not be able to access all available parameters.FLASH Downloading
Software inside the ECM is contained in a Personality Module (FLASH memory chip). FLASH is a memory technology used in the latest Caterpillar Electronic Control Modules. ET has the ability to FLASH download (reprogram) the Personality Module.FLASH downloading is required to update the software. Some machines ECM's have a removable Personality Module. The ECM Personality Module cannot be removed so FLASH downloading is the only means available to update the Personality Module. The Service Replacement ECM may have a removable cover but the Personality Module can not be removed. Do not remove the cover under any circumstances.FLASH downloading is accomplished by connecting ET to the engine through the Communication Adapter Tool and transferring data from a disk drive on ET into the ECM. See the instructions included with the JERD2124 ET software and the JERD2129 ET Data Subscription for more information. A 7X1412 ATA Connector Cable can be used on some models that do not have the ability to FLASH download over the CAT data link.ECM Internal Failure Diagnostic (254-12)
The ECM continuously monitors itself internally for problems. If an internal problem develops the Diagnostic Code 254-12 becomes Active. This indicates that the ECM has detected an internal power supply or memory problem that cannot be fixed. The ECM must be replaced. Refer to Replacing The Electronic Control Module, in this section.Set Injector Codes
This function is used to read/change the numeric 4-digit code stamped on each injector. The Electronic Service Tool will display a list of the codes currently in use. When installing or replacing injectors, ensure that the correct value for each injector is entered. Although the engine control will reject some erroneous values, there is a wide range of values, though not correct, that will be accepted. When replacing an ECM, record the injector codes or use ET Copy Configuration so that they may be entered into the new ECM.System Configuration Parameters (268-02)
System Configuration Parameters are the parameters that affect emissions, power rating of the engine, or various features. They are usually programmed at the factory and in most cases never need to be changed. System Configuration Parameters must be reprogrammed if an ECM is replaced. Proper values for these parameters are available on an Electronic Service Tool (refer to Figure 2.2). Certain parameters are also stamped on the Engine Information Plate. Changing System Configuration Parameters that are protected by factory passwords may void Caterpillar warranty.Engine Serial Number
The Engine Serial Number should be programmed to match the engine serial number stamped on the Engine Information Plate. The serial number is not programmed on a new (replacement) ECM.Equipment ID Number
The Equipment ID Number should be programmed to match the Equipment serial number stamped on the frame. The Equipment ID Number is not programmed on a new (replacement) ECM.Full Load And Full Torque Setting
The Full Load and Full Torque Setting numbers represent the fuel system adjustments performed at the factory to fine tune the fuel system. The assigned values for these parameters are stamped on the Engine Information Plate for each engine. Factory Passwords are required to change these parameters.Status Information
Engine control parameters can be viewed on an Electronic Service Tool. Each parameter has a label to identify it and the current value of the parameter (refer to Figure 2.3). Status information is continually updated and is arranged in a Screen format for ECAP or a Group format for ET. For convenience, several screens or groups have been predefined for the most commonly used parameters. These groups or screens can be customized to display combinations of parameters as required. Some additional parameters not available on the predefined screens may be available on a customized screen. Refer to the ECAP Tool Operating Manual SEHS9343 or the Caterpillar Electronic Technician (ET) Getting Started Manual for further information about programming status screens or groups. Example screens are shown in this section.Personality Module Mismatch Diagnostic (253-02)
The ECM stores a code in permanent memory called an interlock that is associated with each Personality Module part number. The interlock does not allow the engine to run (and potentially cause damage) if the wrong Personality Module is installed or FLASH downloaded into the ECM.When a new Personality Module is FLASH downloaded into the ECM, a Personality Module Mismatch Diagnostic Code (253-02) will be generated if the new Personality Module does not match the last Personality Module used in the ECM.ET will display a warning if a file is downloaded that does not match the previous file in the ECM. If this occurs, the interlock must be programmed with ET to allow the engine to run with the new software.
