Can OBD2 Read Code 87702?

If you’re seeing the code 87702 and wondering if your OBD2 scanner can handle it, you’ve come to the right place. While standard OBD2 scanners are great for common engine-related issues, they might not be equipped to decipher manufacturer-specific codes like 87702. Let’s break down why and explore your options.

Understanding OBD2 Codes and Their Limitations

OBD2 scanners are like the detectives of the automotive world. They plug into your car’s computer (the ECU) and read the Diagnostic Trouble Codes (DTCs) stored there. These codes act like clues, pointing to potential problems within your vehicle’s systems.

Standard OBD2 codes, also known as generic codes, follow a specific format:

• First Character: Indicates the system the code relates to (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: Points to a specific subsystem (e.g., “1” for Fuel and Air Metering, “2” for Fuel and Air Injection)
• Fourth and Fifth Characters: Represent the specific fault within the subsystem

The code 87702, however, doesn’t follow this format. This tells us it’s likely a manufacturer-specific code, meaning it’s unique to a particular car brand.

Why Your OBD2 Scanner Might Not Read Code 87702

Standard OBD2 scanners are primarily designed to read generic codes. They might not have the capability to interpret manufacturer-specific codes, which are often more detailed and specific to a carmaker’s systems.

Think of it this way: You wouldn’t use a basic English dictionary to translate a complex scientific paper in Japanese. Similarly, your standard OBD2 scanner might not have the “vocabulary” to understand the nuanced information encoded in a manufacturer-specific code like 87702.

Deciphering Code 87702: What Are Your Options?

1. Consult Your Owner’s Manual: Your car’s manual often provides a list of manufacturer-specific codes and their meanings. However, be prepared, as some manufacturers are notoriously vague in their descriptions.

2. Online Resources for Your Specific Make and Model: Websites and forums dedicated to your car’s make and model can be invaluable. Fellow car owners often share their experiences and solutions related to specific codes.

3. Advanced OBD2 Scanners: Investing in a more advanced scanner designed to read manufacturer-specific codes can be a game-changer. These scanners often come with extensive code libraries and provide detailed information about the issue.

4. Seek Professional Help: When in doubt, a trusted mechanic with access to manufacturer-specific diagnostic tools is your best bet. They can accurately interpret the code, pinpoint the problem, and recommend the appropriate course of action.

Taking Control of Your Car’s Health

While encountering an unfamiliar code like 87702 can be frustrating, understanding the difference between generic and manufacturer-specific codes empowers you to make informed decisions about your car’s maintenance. Remember, a little knowledge goes a long way in the world of car repair!
