FAQs
Can an OBD2 scanner fix my car?
An OBD2 scanner is a diagnostic tool, not a physical repair tool. It identifies the problem by reading the “Diagnostic Trouble Codes” (DTCs) from your car’s computer. Once you use the information to fix the mechanical or electrical issue, you can then use the scanner to clear the code and turn off the check engine light.
Do these scanners work on Electric Vehicles (EVs)?
Standard OBD2 scanners are designed for Internal Combustion Engines (ICE). While some high-end scanners like the Autel MK808BT can read certain modules on hybrids and EVs, they generally do not offer the same level of depth as they do for gas-powered vehicles. Always check for specific EV compatibility if you own a Tesla or other full EV.
Is there a monthly fee for OBD2 scanners?
Most entry-level and mid-range scanners like BlueDriver and Foxwell have no monthly fees. However, professional-grade tablets like Autel and Launch often provide 1-2 years of free updates and then charge an annual subscription fee to access the latest vehicle software and newest features.
What is Bi-Directional control?
Bi-directional control allows the scanner to send commands to the vehicle, rather than just receiving data. For example, you can use the scanner to tell the car to roll down a window or turn on a cooling fan to see if the part itself is broken or if there is a communication issue in the car’s wiring.
Will an OBD2 scanner tell me why my ABS light is on?
Not all scanners do. Basic “code readers” (like the cheaper ones found in big-box stores) usually only read engine codes (Check Engine Light). You need an “All-System” scanner like the BlueDriver Pro, Autel, or Topdon to read and clear codes for ABS, Airbags (SRS), and Transmission systems.
