In Iveco vehicles, the check engine light is a critical diagnostic tool that prioritizes engine system data to ensure optimal performance and reliability. When illuminated, it indicates that the engine control module has detected discrepancies--ranging from sensor malfunctions, fuel system irregularities, or emissions control issues--that require prompt attention. Utilizing an OBD-II scanner to read specific fault codes is essential, as this data-driven process pinpoints the faulty component and guides effective repairs. By closely monitoring parameters such as fuel injection efficiency, oxygen sensor performance, and catalytic converter integrity, Iveco's advanced onboard diagnostics not only help maintain engine health but also prevent minor issues from escalating into major mechanical failures, thereby safeguarding the vehicle's operational efficiency and longevity.
