This engine management system controls both the fuel injection and the ignition timing.
As shown in the 1004 4-TEC CONTROL SYSTEM illustration, the ECM is the central point of the fuel
injection system. It reads the inputs, makes computations, uses pre-determined parameters and sends
the proper signals to the outputs for proper engine management.
The ECM also stores the fault codes and general information such as: operating conditions, vehicle hours,
serial numbers, customer and maintenance information.
