2. Start the LEXT3037 PC Program.3. Select the engine Personality Module part number to be programmed into the ECM, and proceed with programming the Personality Module. The new ECM is shipped with a blank Personality Module.4. PC Program Personality Module Messages and There Meaning A new ECM comes with a blank (previously unprogrammed) Personality Module. A blank Personality Module will prompt you for all three of the following messages. The information contained in the ECM Display Status screen will be scrambled and meaningless if the module has not been previously programmed (this is normal). Message- "The engine ID in the flash file does not match the engine ID in the ECM."Meaning- The ECM has a Personality Module in it for a different engine, for example, the ECM has a 3406E Personality Module in it, and you are attempting to program a 3176B Personality Module into it.What you should do- Stop the transfer and access information about ECM Status under the Electronic Control Module menu. Make sure the file you are about to transfer is for the same engine it will be installed in.Message- "The application ID in the flash file does not match the application ID in the ECM."Meaning- The ECM has a Personality Module in it for a different application, for example, the ECM has a 3176B Challenger Personality Module in it, and you are attempting to program a 3176B On-Highway Truck Personality Module into it.What you should do- Stop the transfer and access information about ECM Status under the Electronic Control Module menu. Make sure the file you are about to transfer is for the 3176B Challenger application.Message- "The ECM ID in the flash file does not match the ECM ID in the ECM."Meaning- The ECM is not for use in the 3176B Challenger application.What you should do- Stop the transfer and access information about ECM Status under the Electronic Control Module menu. Make sure the ECM on the engine is for a 3176B Challenger application. If you access the ECM Status under the Electronic Control Module menu of the PC Program, but do not follow this information access by programming the Personality Module, you must turn the keyswitch to the OFF position, and then to the ON position before using an Electronic Service Tool or starting the engine. If you do not cycle the keyswitch after reading the ECM Status, the ECM will not communicate with your Electronic Service Tool, or the engine will not start. Cycling the keyswitch is not necessary following successful programming of a Personality Module using the Flash Designer Program.5. Start the engine and check for proper operation. Program any parameters not previously programmed in the old Personality Module if 253-02 Check Customer Or System Parameters (56) code is active. Read the code from the Electronic Service Tool Active Diagnostic Code screen to determine the parameter(s) requiring programming. Remember, on initial power up of a new ECM, three parameters must be programmed to avoid a 253-02 Check Customer Or System Parameters (56) code. They are Full Load Setting (FLS), Full Torque Setting (FTS) and Rating Number. Refer to Programming A New ECM for complete information.
