Control module, ME9 (608)

ECM reads the driver's required power output (torque request) and with the help of several sensors, it calculates the permissible amount of fuel to use in mg/combustion.

Its internal diagnosis can be read directly using the diagnostic tool.

ECM also reads the digital information from the cruise control system switch and, if required by the driver, the engine control module will control the speed of the car.

The radiator fan speed is controlled by ECM.
