A flashing malfunction indicator lamp (MIL), often referred to as an engine light, signifies a severe problem within the vehicle’s engine or related systems. This alert indicates that an issue is present that could potentially cause immediate damage to critical components, such as the catalytic converter. The flashing is a heightened warning compared to a steady light, demanding immediate attention.
Ignoring a flashing MIL can lead to expensive repairs and potential safety hazards. Addressing the problem promptly can prevent further damage, maintain vehicle performance, and ensure compliance with emissions regulations. Historically, the MIL served as a basic indicator. Modern systems offer more diagnostic data accessible through onboard diagnostic (OBD) scanners, facilitating more accurate and efficient repairs.
