For car owners seeking a reliable and affordable way to diagnose car troubles, an OBDII scan tool is an essential tool. While professional-grade diagnostic equipment can cost thousands, there are excellent options available for under $100. This guide will help you find the best OBDII scan tool under $100 to meet your needs.
Understanding Your Needs: OBDII vs. Non-OBDII Systems
Before diving into specific product recommendations, it’s crucial to understand the difference between OBDII and non-OBDII systems. OBDII (On-Board Diagnostics II) is a standardized system that provides access to engine and emissions-related data. Most basic code readers under $100 will cover these functions. However, tasks like reading oil levels, resetting oil change lights, or servicing electric parking brakes often require access to non-OBDII systems, which are manufacturer-specific.
A simple Bluetooth OBDII dongle with a phone app, while inexpensive, typically won’t provide access to non-OBDII systems. They primarily focus on reading OBDII codes related to engine performance and emissions. For instance, while they might detect a faulty oil level sensor, they won’t display the actual oil level.
Affordable Options for Basic Diagnostics: Focusing on OBDII
For basic OBDII diagnostics, several reliable scan tools are available under $100. These devices excel at reading and clearing engine codes, checking sensor data, and monitoring emissions readiness. Popular brands like Veepeak offer a range of options in this price range, providing excellent value for their functionality. Keep in mind that these tools are primarily designed for OBDII diagnostics and won’t offer access to manufacturer-specific systems.
Stepping Up to Non-OBDII: Single-Brand Solutions
If you need to access non-OBDII systems, the Autel DiagLink offers a compelling solution around the $90-$100 mark. The key advantage of the DiagLink is its ability to perform advanced functions like resetting oil change lights and servicing electric parking brakes. However, it comes with a significant caveat: it only works with one car brand.
Upon purchase, you select one brand-specific software to download and install on the DiagLink. While you can purchase additional brand software for around $10 each, the initial limitation is crucial for potential buyers. If you own multiple car brands or plan to change vehicles frequently, the DiagLink might not be the ideal choice.
Multi-Brand Solutions: Investing Slightly More
For multi-brand non-OBDII diagnostics, the Autel MD806, priced around $200, represents a significant step up. Although slightly exceeding the $100 budget, it offers substantial value. The MD806 functions similarly to the DiagLink but supports multiple car brands without requiring separate software downloads for each. It also includes free lifetime software updates, ensuring ongoing compatibility with newer vehicle models. While “lifetime” typically refers to the expected lifespan of the tool, it still represents a valuable feature.
Conclusion: Choosing the Right Scan Tool
Selecting the best OBDII scan tool under $100 depends heavily on your individual needs. For basic diagnostics and code reading, various affordable options exist. However, if you require access to manufacturer-specific non-OBDII systems, consider the Autel DiagLink for single-brand use or invest slightly more in the Autel MD806 for multi-brand compatibility. Carefully evaluating your diagnostic needs will ensure you choose the right tool for the job.
