Illustration 7 g02722357
Typical exampleThe Electronic Control Module (ECM) (1) functions as a governor and a computer for the fuel system. The ECM receives signals from the sensors in order to control the timing and the engine speed.The electronic system consists of the ECM, the engine sensors, and inputs from the parent machine. The ECM is the computer. The personality module is the software for the computer. The personality module contains the operating maps. The operating maps define the following characteristics of the engine:
Engine rating
Torque curves
High and low idle speed (rpm)
Emissions
Injection timingPasswords restrict changes to authorized personnel. Refer to Troubleshooting for more information on the passwords.The ECM has an excellent record of reliability. Any problems in the system are most likely to be the connectors and the wiring harness. The ECM should be the last item in troubleshooting the engine.The programmable software contains all the fuel setting information. The information determines the engine performance.Flash programming is the method of programming or updating the programmable software. Refer to Troubleshooting, "Flash Programming" for the instructions on the flash programming of the programmable software.The ECM is sealed and the ECM needs no routine adjustment or maintenance.
