The engine control unit is a key component for the proper operation of the internal combustion engine. It manages combustion processes, ensures optimal performance, and maintains compliance with emission standards. The ECU responds to driver inputs and current operating conditions through numerous sensors and actuators.
Using diagnostics, it is possible to read and clear fault codes, monitor live data (e.g. fuel pressure, temperatures, engine speed), perform actuator tests (injectors, ignition coils, EGR), initiate diesel particulate filter regeneration, or carry out adaptations after component replacement.
