Check Engine Light Diagnosis

Toyota Onboard Diagnostic System and Check Engine Lights

Toyota manufactures top-selling vehicles, and every model is engineered with an onboard diagnostic system designed to detect problems among primary systems related to reliability, driving comfort, and safety. The onboard diagnostic system uses many sensors positioned within primary systems, constantly monitoring fluids, temperatures, voltage, air, and more. The check engine light illuminates on the dashboard when an onboard diagnostic system’s sensor detects a malfunction. Diagnosis service is necessary to extract the trouble code from the onboard diagnostic system’s computer and verify the problem with an inspection for an accurate and efficient repair.
