This comprehensive guide delves into the meaning behind “OBD2 scanned Nova Blue,” equips you with the knowledge to interpret the results, and empowers you to select the perfect OBD2 scanner for your needs.

Deciphering “OBD2 Scanned Nova Blue”

The message itself doesn’t indicate an error or a problem. It merely confirms that an OBD2 scanner has successfully established communication with your Nova’s onboard computer and completed a scan.

The crucial information lies in the specific trouble codes, also known as Diagnostic Trouble Codes (DTCs), that the scanner retrieves. These codes act as your car’s way of communicating underlying mechanical issues.

Unraveling the Language of Trouble Codes

Don’t let the technical jargon intimidate you! Trouble codes, while seemingly cryptic, are your gateway to understanding your car’s needs. They consist of a five-digit alphanumeric combination:

• First Character: Indicates the system where the issue lies (e.g., “P” for Powertrain, “B” for Body, “C” for Chassis, “U” for Network).
• Second Character: Specifies whether the code is generic (0) or manufacturer-specific (1).
• Third Character: Pinpoints the specific system within the broader category (e.g., “1” for Fuel and Air Metering, “2” for Fuel and Air Injection).
• Fourth & Fifth Characters: Represent the specific fault within the system.

For instance, a code “P0301” translates to “Powertrain, Generic, Cylinder 1 Misfire Detected.” Understanding these codes empowers you to take the right course of action.
