1. What Are the Basic Types of OBD2 Scanners Available?

There are several types of OBD2 scanners available, ranging from basic code readers to advanced professional-grade tools, each offering different levels of functionality and diagnostic capabilities.

The types are categorized as follows:

• Plain-Version Scan Tools: These are the most basic, typically wired, and primarily read P-codes (powertrain codes, or check engine light codes). They provide the code, which you then have to look up manually. Most offer a readiness status to check if all self-checks have been completed since the last code clearing and allow you to clear the P-codes. These usually cost between $15 and $50.

• Second-Tier Scan Tools: These offer additional features such as checking ABS (Anti-lock Braking System) codes and may have some live data recording capabilities. They range in price from $100 to $500.

• Semi-Pro and Pro Tools: These bidirectional tools provide a comprehensive set of capabilities similar to what a professional shop would have, excluding dealer-hidden features. Prices range from around $300 to $4000. These tools can perform tasks like assigning new TPMS (Tire Pressure Monitoring System) sensors and running self-tests. Some advanced models can reset fuel maps and perform other sophisticated functions.

• Bluetooth Dongles: These are small, inexpensive wireless Bluetooth dongles that plug into the OBD port. Paired with a smartphone or tablet app like Torque Pro, they offer constant monitoring and diagnostics of numerous vehicle parameters. They generally cost between $9 and $20.

• Dealer Diagnostic Software: This involves using a car-specific connector that attaches to the engine diagnostic port and plugs into a laptop. By downloading “bootleg” dealer diagnostic software (like TechStream for Toyota), users gain access to the full suite of dealer diagnostic capabilities.

Each type of scanner caters to different needs and levels of technical expertise. The choice depends on factors like budget, the complexity of the diagnostics required, and whether the user is a DIY enthusiast or a professional mechanic.
