Many drivers have encountered this common scenario – starting up the car and seeing the check engine light appear. When that indicator lights up, your anxiety levels may also elevate. There are a host of problems associated with the check engine light, but many of them are harmless issues that won’t cost a lot of money to rectify. Consider buying a code reader for your vehicle to get a clearer idea of the problem.
The Need for Vehicle Diagnostics
In most modern car models, the computerized system features a diagnostic tool that helps mechanics understand when there is a problem. This system is called the On-board diagnostics or OBD.
OBD codes help vehicle owners and mechanics understand the extent of an issue and eliminate the need to take apart major components of the car for diagnostic purposes. This helps you save money on car repairs and save time on waiting for your car to get fixed. Lots of vehicle owners have their own code reader to give them information about a potential problem.
Choosing the Right Code Reader for Your Needs
If you want to buy a code reader for cars, you need to understand how these devices work. There are different models at various price points available for consumers to buy.
Basic code readers will only show the error code on their display. Vehicle owners can take that information and use the internet to look up the code to understand the problem with their car. Code scanners are more expensive and do more than just identify the error code. They can reset the check engine light and provide live data pinpointing the problem.
Using a Code Reader
For a typical code reader, like the Innova obd2 code reader, there is a simple and fast process to figure out the error code. First, hook up the code reader to the OBD port under the steering wheel in your vehicle.
To activate the OBD tool, you need to insert your key into the ignition and turn it to the on setting without starting the car. For newer models without an ignition and key slot, you may need a different process, so you should consult your owner’s manual. Once activated, the code reader will display one or more error codes.
Error Codes and What They Mean
The OBD coding system follows an easy-to-understand format. The code generated by the reader includes both letters and numbers. The first character will be one letter, either P, C, B or U. This indicates which system has an error, such as the powertrain, chassis, body or network.
The second character is a numeral and identifies the system fault. The third and fourth characters, also numerals, give information about the location or nature. The final character, a numeral, identifies the severity of the problem.
Troubleshooting Code Readers
Using a code reader may have a learning curve. Sometimes, the port may not allow a connection to the code reader. Here, check the tool’s batteries, look at the port to make sure the pins are secure or ensure your car’s OBD outlet is not dirty or dusty.
Save yourself time and money on vehicle repairs by identifying the problem yourself. Using a code reader gives you the power of information by indicating your car’s error code.
