Infiniti vehicles utilize a sophisticated onboard diagnostic system designed to monitor engine performance and immediately flag critical issues by illuminating the check engine light. This alert prioritizes essential data--such as abnormal sensor readings, misfires, or emissions irregularities--by providing a clear, rapid signal that something may be amiss with the engine or related systems. Leveraging integrated diagnostic codes and real-time performance metrics, Infiniti ensures drivers receive accurate and timely insights into their vehicle's health, paving the way for prompt maintenance and optimized performance while safeguarding reliability and safety on every drive.
