What are some possible reasons for failing the OBD check on a vehicle inspection?
- The vehicle’s OBD system connector has been removed or is otherwise not working properly. The OBD check cannot be completed if the connector is missing or is not working properly.
- The Malfunction Indicator Light does not illuminate when the ignition key is turned to the “on” position. When the vehicle’s OBD system detects a problem, it turns on the warning light to alert the driver of a problem. However, if the light cannot illuminate because the bulb has burned out or is otherwise not working, the driver would not be alerted to the problem.
