Comprehensive FAQ Guide to OBD2 Scan Tools 2.0

In the last blog, Guide to OBD2 Scan Tools 1.0, we talked about how to determine the scan tool you need, what features should be considered and where to check the compatability. In this Guide to OBD2 Scan Tools 2.0, we'll go on discussing purchase considerations.

How Accurate Are Diagnostic Scan Tools?

Diagnostic scan tools are generally very accurate, but their precision can depend on several factors:

  • Quality of the Tool: High-quality, professional-grade tools tend to be more accurate than basic models.
  • Regular Updates: Tools that receive regular software updates are more accurate as they stay current with new vehicles and diagnostic procedures.
  • User Expertise: The accuracy also depends on how well the user understands and interprets the data provided by the tool. A scan tool will help you locate and pinpoint faults however sometimes manual fault finding/ testing and the process of elimination might also be required

 

 Are There Any Subscription Fees for Using Certain Scan Tools?

Basic scan tools will generally have lifetime free updates.

Professional scan tools, on the other hand, often require subscription fees. Depending on the brand and model, you typically receive 1 to 3 years of free updates. After this period, you don't have to pay for updates unless you choose to do so. 

 

How Do I Choose Between a Wired and Wireless Scan Tool?

Choosing between a wired and wireless scan tool depends on your personal preference and needs. Consider the following:

  • Mobility: A wireless (Bluetooth) scan tool allows you to move freely around the vehicle without being tethered by a cable.
  • Cost: Bluetooth scan tools are generally more expensive than wired ones.
  • Risk of Loss: Bluetooth dongles can be accidentally left in a customer's car, which can be a costly mistake.

Think about your specific needs and work habits when making your decision.

 

What is the Typical Lifespan of a Diagnostic Scan Tool?

The lifespan of a diagnostic scan tool can vary depending on several factors:

1. Quality: High-quality tools from reputable manufacturers tend to have longer lifespans than cheaper, lower-quality tools.

2. Frequency of Use: Tools used frequently may wear out more quickly than those used infrequently.

3. Memory/Storage Space: The main reason we see scan tools not accept updates is because the memory is full and the tool will no longer update. Its important to clear out the memory on your tools storage ,also delete files and vehicle history that is no longer required.

While there's no fixed lifespan for a scan tool, with proper care and maintenance, a good-quality tool can last 8-10 years.
