For car owners and automotive enthusiasts, understanding your vehicle’s health is crucial. OBD2 scanners have become indispensable tools for diagnosing issues, reading error codes, and even performing advanced functions. While basic scanners can be found at retailers like Walmart and auto parts stores such as O’Reilly’s, Pep Boys, AutoZone, Advanced Auto Parts, and Napa, the market offers a wide range of options, including professional-grade tools. Among the respected brands in the automotive industry, Cornwell Tools stands out, but how does a Cornwell Obd2 Scanner stack up, and is it the right choice for you?
Basic OBD2 Scanners vs. Advanced Options
The most basic OBD2 scanners, often priced between $50 and $100, are designed for fundamental tasks. They excel at reading and clearing Diagnostic Trouble Codes (DTCs), Malfunction Indicator Lamps (MILs), and other basic codes. These scanners are readily available at the stores mentioned earlier and are sufficient for simple diagnostics. However, their capabilities are limited. Many basic scanners cannot perform advanced functions like live data streaming, bidirectional control, or system resets.
For those needing more in-depth diagnostics and functionality, stepping up to a more advanced OBD2 scanner is necessary. Brands like Innova, Autel, Actron, Snap-on, Cornwell, and Matco offer scanners with enhanced features. These brands are known for producing tools that professionals rely on daily. You can often find these brands at specialized tool retailers or directly from the manufacturers’ websites, such as Innova.com, Autel.com, Snapon.com, Cornwelltools.com, and Matcotools.com.
Cornwell OBD2 Scanners: Professional Quality and Features
Cornwell OBD2 scanners are positioned within this higher tier of diagnostic tools. Cornwell Tools has a long-standing reputation in the automotive technician community for producing durable and reliable equipment. While they may not be as widely recognized by general consumers as some other brands, within the professional automotive world, Cornwell OBD2 scanners are highly regarded.
These scanners are built to offer a comprehensive diagnostic experience. Typically, a Cornwell OBD2 scanner will go beyond basic code reading and clearing, providing features such as:
- Live Data Streaming: View real-time data from various vehicle sensors to pinpoint intermittent issues.
- Bidirectional Control: Actively test components and systems to verify functionality.
- Advanced System Diagnostics: Access to systems beyond engine and transmission, such as ABS, SRS, and body control modules.
- Special Functions: Service resets, adaptations, and programming capabilities that vary depending on the model and vehicle.
Finding Deals on Professional Scanners
The original article mentions a resourceful tip: pawnshops. Pawnshops can be a surprisingly good source for used tools, including higher-end OBD2 scanners. The author recounts finding a barely used Autel Maxicheck 808 at a pawnshop for a significantly reduced price. This highlights that it’s possible to acquire a professional-grade scanner, potentially including a Cornwell OBD2 scanner, for less than retail if you are willing to explore alternative sources like pawn shops.
Real-World OBD2 Scanner Capabilities
The original article provides examples of what a more advanced scanner, like the Autel Maxicheck 808, can do on various vehicles. These examples, while specific to Autel, illustrate the kind of expanded access and control you might expect from a higher-end scanner, potentially including certain Cornwell OBD2 scanner models, depending on their features and software:
- 2011 Jeep Grand Cherokee (JGC) Limited: Programming remotes, push start module, and accessing systems like ignition, steering, fuel pressure, ABS, and TPIM. The ability to monitor system status (on/off) for components like brakes, lights, and HVAC.
- Kia Koup: System access, although potentially limited by Kia’s software security without specific VCI and JBox interfaces. Still capable of monitoring system status for various components.
- 2007 Toyota Scion TC: Access to nearly all modules, sensors, engine, transmission, fuel, exhaust, and more. System recalibration and safe mode capabilities. Extensive system status monitoring.
These examples demonstrate the significant leap in functionality from basic scanners to more advanced tools. While a basic scanner will tell you there’s a problem (via a code), an advanced scanner like a Cornwell OBD2 scanner offers the potential to diagnose more deeply, perform tests, and even carry out some repairs or system adjustments.
Conclusion: Is a Cornwell OBD2 Scanner Right for You?
Deciding on the right OBD2 scanner depends on your needs and budget. If you only need to occasionally read and clear basic engine codes, a simple, inexpensive scanner from Walmart or an auto parts store might suffice. However, if you are serious about automotive diagnostics, work on cars frequently, or desire deeper system access and functionality, then investing in a professional-grade scanner is worthwhile.
Cornwell OBD2 scanners, along with brands like Innova, Autel, Snap-on, and Matco, represent the higher end of the market. They offer robust features, professional-level diagnostics, and the durability expected from a tool designed for daily use in a shop environment. While they come with a higher price tag than basic scanners, the capabilities and long-term value they provide can be significant, especially for those who are passionate about car repair or work in the automotive industry. Exploring options like pawnshops might also make these professional tools, including a Cornwell OBD2 scanner, more accessible.
