Frequently Asked Questions (FAQs)
Q: What’s the difference between V1.5, plastic, and Bluetooth ELM327 scanners?
A: Functionally, they are very similar. The main difference lies in the interface. V1.5 ELM327 scanners often have both USB and COM interfaces. Plastic ELM327 scanners typically have a USB interface. Bluetooth ELM327 scanners are wireless, connecting via Bluetooth and eliminating the need for cables.
Q: I see a “TEST” icon in my software, but it says “not implemented in this version.” What does it mean?
A: The “TEST” icon likely refers to advanced diagnostic functions (like Mode 5, 6, & 7 tests) that might not be fully supported in all software versions or may require specific COM port settings. Refer to the provided manuals, particularly the “ComPort.PDF” guide mentioned in the original article, for instructions on COM port configuration if needed.
Q: Can I use this scanner to read ABS or Airbag codes?
A: Basic ELM327 scanners are primarily designed for engine and transmission diagnostics. While they excel at reading and clearing engine fault codes, accessing systems like ABS and Airbag often requires more advanced and often more expensive professional-grade scanners.
