Electronic Control Unit
1.Description & Working Principle
The ECU continuously monitors the operating conditions of the engine through the system
sensors. It also provides the necessary computation, adaptability, and output control in order to
minimize the tailpipe emissions and fuel consumption, while optimizing vehicle drivability for all
operating conditions. The ECU also provides diagnosis when system malfunctions occur.
