Enter the full OBD code, and the website will return full details on the fault experienced and how to fix it.The windshield stickering process that was implemented in February 2018 now applies to all 20 years old and newer vehicles that require an OBD inspection.

With thousands of potential faults, to get the exact details of the issue, you’ll need to go online and use one of the many OBD Code interpretation websites, such as. The final two characters of the OBD code specify the exact fault. Step 8: Interpret the final characters of the OBD code In the case of powertrain issues, a 1 indicates a fuel or air metering system problem, a 2 means there’s a fuel or air metering injection system issue, a 3 indicates a problem with the ignition system, a 4 is an emissions systems error, a 5 is a speed control or idle control issue, a 6 is a computer/electronics problem, and a 7-9 indicates that something’s wrong with the transmission. Each type of issue (powertrain, body, chassis, network communication system, etc.) has its own interpretation for this number. The third character gives us even more specific information on where the problem lies.

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 aren’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 it’s a U, the network communication system has an issue. If the first character is a C, there’s a problem in the chassis, such as an issue with the anti-lock brakes. If it’s a B, there’s something wrong in the body system, which could indicate an issue with the airbags, for example. If the first character is a P, there’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 haven’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, you’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, you’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 there’s no voltage going to the power outlet, then the OBD scanner won’t work either. If it’s still not working, check whether there is power coming through the car’s auxiliary power outlet (aka the cigarette lighter). If the scanner doesn’t light up when you switch on the ignition, check the connection between the scanner and the connector pins. You’ll see a message like “establishing link with OBD” while the scanner is initiating. Turning on the ignition will send power to the OBD scanner, which will begin communicating with the vehicle’s on-board computer.
Turn on the ignition in the vehicle, but don’t start the engine.

Check your owner’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, you’ll find it under the driver’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 vehicle’s OBD port.
