What is included in a vehicle diagnostic?
Car diagnostic tests scan your car’s components and systems to check for issues with components like the engine, transmission, oil tank, throttle, and many more. Because car diagnostic tests require specific devices and expertise to read correctly, most tests are performed with mechanics or at dealer shops.
Where is the onboard computer on a car?
Most modern vehicles allow for you to tap into those sensors to run diagnostics via a connection to the computer called an OBD2 port. Although it varies form vehicle to vehicle, most OBD2 ports are located under the dash so that a technician can have easy access for their diagnostic tools. Why bother connecting to my onboard computer?
When did the on-board diagnostics system come out?
The amount of diagnostic information available via OBD has varied widely since its introduction in the early 1980s versions of on-board vehicle computers.
How are on-board diagnostics used in OBD systems?
On-board diagnostics. Modern OBD implementations use a standardized digital communications port to provide real-time data in addition to a standardized series of diagnostic trouble codes, or DTCs, which allow one to rapidly identify and remedy malfunctions within the vehicle.

What are the diagnostic ports on a car?
Regulations concerning onboard diagnostics were put in place to monitor vehicle emissions with scan tools plugged into the ports for reading data from the vehicle. Onboard diagnostic systems were developed in the late 1960s, originally to scan engine performance and diagnose vehicle faults.
Why do we need on board diagnostics in cars?
One of the effects of this law is the mandate for the on-board diagnostic (OBD-II) port and a related subsequent standard. This port allows anyone connecting to it access to the vehicle to monitor the performance and function. With the smartphone revolution, sensors and microprocessors have become increasingly cheaper and miniaturized.
What is the purpose of an onboard diagnostic?
Besides checking for emissions, onboard diagnostics are also useful for diagnosing vehicle faults, confirming the vehicle’s wellness and safety, and providing information on the vehicle’s service and maintenance schedules.
What do you need to know about OBD-I?
OBD-I refers to the first generation of on-board diagnostic systems, which featured proprietary connectors, hardware interfaces, and protocols.
