– Explanation of OBD-II Codes
– Importance of OBD-II Codes
– How to Retrieve OBD-II Codes

OBD-II codes are a set of diagnostic codes that are standardized across all modern vehicles. These codes can be retrieved using an OBD-II scanner that reads data from the vehicle’s onboard computer system. The codes can help mechanics and DIY enthusiasts to diagnose and repair various issues with a vehicle. OBD-II codes come in the form of five-digit alphanumeric codes, beginning with a letter P, followed by four numbers. Each code corresponds to a specific issue with the vehicle.
