Code Readers are basic devices that can read and clear codes from any OBD-II equipped vehicle.OBD-II scanners are the tools that are used to read DTCs. Often, performance gains from OBD come at the expense of other qualities, like fuel economy and reliability.

There are also performance tuners, which connect to the OBD port and can remap the vehicle’s software to increase power output among other things. Some companies even make dongles for the purpose of monitoring a vehicle’s system, whether for tuning or keeping tabs on a young driver’s speeds. The system uses your vehicle’s sensors to determine whether something has gone wrong, but some sensors can even read real-time information from the sensors. OBD was made for diagnostics, but it is also heavily used in tuner circles by those who are looking to get better performance out of their rides. Some code readers will figure out what the code means for you, but if you just get the code, you may need to look up exactly what it means. Codes that begin P1_ are manufacturer specific, meaning they will indicate different things depending on the make There are codes for the powertrain, body, chassis, and network: DTCs typically start with a letter to indicate the system affected followed by five digits to specify the issue. When a code reader is connected to the port, it is capable of reading the diagnostic trouble codes that are stored in the system. If you’re having trouble finding it, check your owner’s manual. This port is typically located near or under the steering wheel column, although it is sometimes located near the center of the dash or center console, or under the glove box. It is also the port that is typically used for state vehicle inspections. The OBD port is an electrical plug that OBD-II scanners, code readers, and other devices can be plugged into to access the OBD-II system.

ISO 15765 CAN: Controller Area Network is used on all vehicles manufactured after 2008.ISO14230-4 (KWP2000): Keyword Protocol is used in a variety of European and Asian imports as well as Honda, Jeep, Land Rover, Subaru, Mazda, Nissan, and more.ISO9141-2: All Chrysler and a variety of European or Asian vehicles use this protocol.SAE J1850 VPW: Variable Pulse Width protocol is used in General Motors vehicles.SAE J1850 PWM: Pulse Width Modulation protocol is used in Ford vehicles.The system was standardized with specifications from the Society of Automotive Engineers (SAE) to comply with California Air Resources Board (CARB) regulations. Now most OBD-II systems are nearly the same, but there are five different protocols with slight variations. Before The standardized OBD-II system eliminates the necessity for multiple adapters and scanner accessories. OBD-II is a more standardized version of this system, making it easy to diagnose issues across different vehicles.
