Agreement OBD codes is a vital attribute of vehicle maintenance as part of a strong armada tracking and direction strategy.
When the Check Engine light pops on, it tin betoken a wide range of problems with your vehicle. Symptoms of the problem may not be apparent, and a uncomplicated light on its own tin't tell you whether the consequence lies with the fuel system, ignition, transmission, estimator circuitry, emission controls, or elsewhere.
Modern vehicles accept onboard diagnostic computers (OBDs) that enable a mechanic with the right tools to quickly sympathize any problem that the vehicle is experiencing. When something goes wrong, the OBD computer stores a 5-alphabetic character diagnostic trouble code (DTC) that summarizes the issue at hand. These are as well normally known every bit OBD codes or OBD-Two codes.
Through the use of an OBD scanner, you can get this five-letter code from the vehicle so you know exactly what needs attending.

How to read OBD codes: Preparation
Reading OBD codes requires an OBD scanner, which tin can cost between $thirty and $60. It's a handheld tool with a xvi-pivot trapezoidal connector that plugs into the vehicle and interprets the OBD code. You lot don't need whatever other tools, just access to the interior of the vehicle.
Step 1: Plug the OBD scanner into the OBD port
Your OBD scanner has a 16-pin trapezoidal connector that fits into the vehicle's OBD port. This is likewise known as the diagnostic link connector (DLC). Each vehicle has a different location for the OBD port, merely almost of the time, you lot'll find it under the commuter'south side dashboard near the pedals. In rare cases, it volition be in the center dashboard or below the glove compartment. Check your possessor'southward transmission for the precise location of your DLC.
Step 2: Turn on the ignition
Turn on the ignition in the vehicle, but don't start the engine. Turning on the ignition will send power to the OBD scanner, which will begin communicating with the vehicle's on-lath estimator. Yous'll see a message like "establishing link with OBD" while the scanner is initiating.
If the scanner doesn't low-cal upwardly when you switch on the ignition, check the connection betwixt the scanner and the connector pins. If it's still not working, check whether there is power coming through the car's auxiliary power outlet (aka the cigarette lighter). The OBD organization gets its power from the same circuit, so if in that location'south no voltage going to the power outlet, so the OBD scanner won't piece of work either.
Step 3: Enter the Vehicle Identification Number
With some OBD scanners, yous'll have to enter the Vehicle Identification Number (VIN), make, model, and engine type of the vehicle. This is because some OBD codes are manufacturer-specific, and so the scanner volition be able to requite y'all more accurate data if yous enter more details about your specific vehicle.
Next, navigate to the Codes menu on your OBD scanner. Each scanner is unlike, only typically, it will exist called Codes or Trouble Codes.
In many cases, you'll also be asked to choose between Active Codes and Pending Codes. Active Codes refer to malfunctions that are causing your Bank check Engine light to stay on. Pending Codes are errors that have occurred at least once but haven't still caused the Check Engine low-cal to trip. If the blazon of error happens again, though, the Awaiting Code will be updated to an Agile Code, and the Check Engine low-cal will turn on.
Step v: Interpret the showtime character of the OBD lawmaking
Now you have the OBD lawmaking, you demand to be able to interpret what it means. Each character of the code tells you something about the error. The commencement ane gives you an overview of the issue at hand.
If the first character is a P, there'due south a problem with the powertrain system. If it's a B, there's something wrong in the body system, which could indicate an effect with the airbags, for case. If the first character is a C, at that place's a trouble in the chassis, such every bit an issue with the anti-lock brakes. If it's a U, the network communication system has an issue.
Step vi: Interpret the 2d graphic symbol of the OBD code
The second character in the code defines whether the problem is a generic consequence or a manufacturer-specific issue. When creating the OBD code system, the Order of Automotive Engineers chose standard codes for problems that can occur on almost cars. These are known as generic codes. Some manufacturers have added their own codes because their parts aren't accurately reflected in the generic listing. These are the manufacturer-specific codes.
Look at the showtime two characters of the OBD lawmaking. If they are P0, P2, P34-P39, B0, B3, C0, C3, U0, or U3, the upshot is generic. If they are P1, P30-P33, B1, B2, C1, C2, U1, or U2, the problem is manufacturer specific.
Most of the time, the issue will exist P0 or P1, which specifies that there's a problem somewhere in the powertrain arrangement.
Footstep 7: Translate the third character of the OBD lawmaking
The third graphic symbol gives u.s.a. even more specific information on where the problem lies. Each type of upshot (powertrain, trunk, chassis, network communication system, etc.) has its own interpretation for this number.
In the example of powertrain issues, a i indicates a fuel or air metering system problem, a 2 ways there's a fuel or air metering injection system issue, a 3 indicates a problem with the ignition system, a iv is an emissions systems error, a 5 is a speed control or idle control outcome, a 6 is a computer/electronics trouble, and a 7-nine indicates that something's wrong with the transmission.
Step 8: Interpret the final characters of the OBD code
The final two characters of the OBD code specify the exact fault. With thousands of potential faults, to get the exact details of the outcome, y'all'll need to go online and use one of the many OBD Lawmaking interpretation websites, such as OBD-Codes.com. Enter the full OBD lawmaking, and the website will return full details on the fault experienced and how to set up it.
Summary
Modern vehicles brand diagnosing vehicle trouble easier through the use of OBD codes. You lot tin use an OBD scanner to find out why your Check Engine light is on. The five-character code details the vehicular system that'south experiencing a problem, and yous can even translate the lawmaking yourself by examining its characters.
However, at that place are and then many possible OBD codes, it's usually easier to enter the OBD code returned by your scanner into an OBD Code interpretation website to observe out what that specific code means.
