| What Is OBD II? | ||
|
On Board Diagnostics-Second Generation (OBD II), is a computerized system
on 1996 & newer model year gasoline and light-duty trucks that monitors the
operation of emissions-related components and systems. This sophisticated system detects malfunctioning or deteriorating components and systems before more serious failures occur. Even before the driver of the vehicle might notice a problem. The OBD II alerts a vehicle owner to the need for repairs before more costly damage occurs. When a malfunction is detected by the vehicle's OBD II system, a diagnostic trouble code(DTC) is stored in the computer's memory and a "Check Engine" light comes on.The stored trouble codes (DTCs) can be read using an OBD II scan tool that plugs into the vehicles OBD II computer. Further diagnosis by a skilled automotive repair technician is needed to determine the most appropriate repairs. |
