Most of the time, the issue will be P0 or P1, which specifies that thereвЂ™s a problem somewhere in the powertrain system. If they are P1, P30-P33, B1, B2, C1, C2, U1, or U2, the problem is manufacturer specific. If they are P0, P2, P34-P39, B0, B3, C0, C3, U0, or U3, the issue is generic. Look at the first two characters of the OBD code. These are the manufacturer-specific codes. Some manufacturers have added their own codes because their parts arenвЂ™t accurately reflected in the generic list.

When creating the OBD code system, the Society of Automotive Engineers chose standard codes for problems that can occur on most cars. The second character in the code defines whether the problem is a generic issue or a manufacturer-specific issue. Step 6: Interpret the second character of the OBD code

If itвЂ™s a U, the network communication system has an issue. If the first character is a C, thereвЂ™s a problem in the chassis, such as an issue with the anti-lock brakes. If itвЂ™s a B, thereвЂ™s something wrong in the body system, which could indicate an issue with the airbags, for example. If the first character is a P, thereвЂ™s a problem with the powertrain system. The first one gives you an overview of the issue at hand. Each character of the code tells you something about the error. Now you have the OBD code, you need to be able to interpret what it means.

Pending Codes are errors that have occurred at least once but havenвЂ™t yet caused the Check Engine light to trip. Active Codes refer to malfunctions that are causing your Check Engine light to stay on. In many cases, youвЂ™ll also be asked to choose between Active Codes and Pending Codes. Each scanner is different, but typically, it will be called Codes or Trouble Codes. Next, navigate to the Codes menu on your OBD scanner. This is because some OBD codes are manufacturer-specific, so the scanner will be able to give you more accurate information if you enter more details about your specific vehicle. With some OBD scanners, youвЂ™ll have to enter the Vehicle Identification Number (VIN), make, model, and engine type of the vehicle. Step 3: Enter the Vehicle Identification Number The OBD system gets its power from the same circuit, so if thereвЂ™s no voltage going to the power outlet, then the OBD scanner wonвЂ™t work either. If itвЂ™s still not working, check whether there is power coming through the carвЂ™s auxiliary power outlet (aka the cigarette lighter). If the scanner doesnвЂ™t light up when you switch on the ignition, check the connection between the scanner and the connector pins. YouвЂ™ll see a message like вЂњestablishing link with OBDвЂќ while the scanner is initiating.

Turning on the ignition will send power to the OBD scanner, which will begin communicating with the vehicleвЂ™s on-board computer. Turn on the ignition in the vehicle, but donвЂ™t start the engine.

Check your ownerвЂ™s manual for the precise location of your DLC. In rare cases, it will be in the center dashboard or below the glove compartment.

Each vehicle has a different location for the OBD port, but most of the time, youвЂ™ll find it under the driverвЂ™s side dashboard near the pedals. This is also known as the diagnostic link connector (DLC). Your OBD scanner has a 16-pin trapezoidal connector that fits into the vehicleвЂ™s OBD port.

ItвЂ™s a handheld tool with a 16-pin trapezoidal connector that plugs into the vehicle and interprets the OBD code. Reading OBD codes requires an OBD scanner, which can cost between $30 and $60.

Through the use of an OBD scanner, you can get this five-letter code from the vehicle so you know exactly what needs attention. These are also commonly known as OBD codes or OBD-II codes. When something goes wrong, the OBD computer stores a five-letter diagnostic trouble code (DTC) that summarizes the issue at hand. Modern vehicles have onboard diagnostic computers (OBDs) that enable a mechanic with the right tools to quickly understand any problem that the vehicle is experiencing. Symptoms of the problem may not be apparent, and a simple light on its own canвЂ™t tell you whether the issue lies with the fuel system, ignition, transmission, computer circuitry, emission controls, or elsewhere. When the Check Engine light pops on, it can indicate a wide range of issues with your vehicle.
