You’ve seen the commercials: a sleek device plugs into your car’s dashboard, instantly diagnosing engine trouble and saving you hundreds in mechanic fees. These “as seen on TV” car diagnostic computers seem like a dream come true for car owners tired of expensive repair bills. But are they too good to be true?
This article delves into the world of car diagnostic computers, separating hype from reality and helping you decide if these devices are a worthwhile investment. We’ll explore their features, limitations, and compare them to professional-grade diagnostic tools.
Understanding Car Diagnostic Computers
Modern vehicles are complex machines with sophisticated computer systems monitoring everything from engine performance to airbag deployment. When a problem arises, the car’s computer stores a Diagnostic Trouble Code (DTC) in its memory. A car diagnostic computer, also known as an OBD2 scanner, reads these codes and translates them into understandable terms, giving you insight into what might be wrong with your car.

What Can a Car Diagnostic Computer Do?
While the capabilities vary depending on the model and price, here are some common functions of car diagnostic computers:
- Read and Clear DTCs: This is the primary function, allowing you to identify potential issues and clear codes after repairs.
- Display Live Data: Some scanners show real-time information like engine speed, coolant temperature, and oxygen sensor readings, helpful for monitoring car performance.
- View Freeze Frame Data: This feature captures a snapshot of the engine’s parameters when a DTC is stored, providing context for diagnosing intermittent problems.
- Check Emissions Readiness Status: See if your vehicle is ready for an emissions test and identify potential problems beforehand.
“As Seen on TV” vs. Professional-Grade Scanners
While those “as seen on TV” car diagnostic tools might seem tempting, it’s crucial to understand their limitations compared to professional-grade scanners used by mechanics:
Functionality
- Basic vs. Advanced Diagnostics: TV-advertised scanners often offer basic code reading and clearing. In contrast, professional tools can access manufacturer-specific codes, perform bi-directional tests (sending commands to car components), and offer advanced programming functions.
Coverage
- Limited Vehicle Compatibility: Budget-friendly scanners may not support all car makes and models, especially older vehicles. Professional tools typically have broader compatibility and regular software updates to stay current.
Data Interpretation
- Simplified vs. Detailed Information: While translating DTCs into plain language is helpful, understanding the underlying cause often requires technical expertise. Professional scanners offer more detailed data and access to repair databases, aiding accurate diagnosis.
Are “As Seen on TV” Car Diagnostic Computers Worth It?
For car enthusiasts and DIYers, a basic car diagnostic computer can be a valuable tool for:
- Early Problem Detection: Identify minor issues before they become major headaches, potentially saving on costly repairs.
- Resetting Check Engine Light: Avoid unnecessary trips to the mechanic for simple fixes like a loose gas cap.
- Empowering Car Owners: Gain a basic understanding of your car’s health and communicate more effectively with mechanics.
However, it’s crucial to manage expectations:
- Not a Replacement for Professional Diagnosis: These devices are helpful for preliminary checks, but they can’t replace a qualified mechanic’s expertise for complex issues.
- Misinterpretation Can Be Costly: Acting solely on information from a basic scanner without proper understanding can lead to incorrect repairs and wasted expenses.
Choosing the Right Car Diagnostic Computer
When purchasing a car diagnostic computer, consider the following factors:
- Vehicle Compatibility: Ensure the scanner supports your car’s make, model, and year.
- Features: Determine the level of detail and functionality you need (code reading, live data, etc.).
- User Interface: Choose a scanner with a clear, easy-to-navigate display and user-friendly software.
- Reviews and Ratings: Research reputable brands and read customer reviews to assess performance and reliability.
Conclusion
While “as seen on TV” car diagnostic computers might not be miracle cures, they can be helpful tools for car owners seeking basic insights into their vehicle’s health. By understanding their capabilities and limitations, you can make informed decisions about car maintenance and potentially save money in the long run. Remember, knowledge is power, and even a basic understanding of car diagnostics can empower you as a car owner.
