FAQs — OBD Scan Tools

What is the best scan tool for Holden vehicles?

For Holden vehicles, the Vident i400AU ALDL OBD Scan Tool or Vident iLink400MAX are our top recommendations. Specifically designed to support Australian OBD1 and ALDL protocols used in earlier model Holden models including the VR, VS, VT, VX Commodores, Astra, Barina and more — coverage that most generic OBD2 scanners simply can't provide. For newer Holdens including VY, VZ, VE, VF that use standard OBD2, any full-system scan tool in our range will work effectively.

What is the best OBD2 scanner for home mechanics in Australia?

For home mechanics, the best OBD2 scanner depends on how deep you need to go. If you just want to read and clear fault codes, a basic OBD2 code reader starting under $50 is all you need. If you want to cover multiple systems like ABS, airbags and transmission, a mid-range multi-system scan tool in the $200–$500 range is the sweet spot for most home mechanics. Our most popular choices for DIY users can be found in our top 5 scan tools in Australia 2026 blog post — all offering excellent coverage for Australian vehicles without the complexity of a professional workshop tool.

What scan tool do professional mechanics use?

Professional mechanics typically use full-system bi-directional scan tools that can not only read faults but actively test and control vehicle components. Our professional scan tool range includes trusted workshop brands like Autel, Launch and Vident — tools that offer ECU coding, active tests, live data streaming, key programming and the widest vehicle coverage. The Launch X431 PROS V5 or Autel MaxiSys MS906 Pro are among the most popular choices for independent workshops across Australia.

What is the difference between OBD1 and OBD2?

OBD1 is the older diagnostic system used in most vehicles manufactured before 1996 globally, and before approximately 2006 in Australia. It varies significantly between manufacturers — Holden, Mitsubishi and Toyota all used different protocols, which is why you need a specific tool to access these non-standard protocols such as ALDL, Nissan Consult, MUTII etc. OBD2 is the standardised system introduced globally from the mid-1990s onwards — it uses a universal 16-pin connector and is compatible with any OBD2 scan tool. If your car was made after around the mid 2000s and is sold in Australia, it will likely use OBD2 — you can check our OBD2 compatibility page.

Can a scan tool turn off the check engine light?

Yes — any scan tool or OBD2 code reader can read and clear the fault codes that trigger the check engine light, which turns the light off. However it's important to understand that clearing the code doesn't fix the underlying problem — if the fault is still present, the light will come back on. The right approach is to read the fault code first, understand what it means, address the root cause, and then clear the code. If your check engine light keeps returning, it's a sign something needs attention rather than just resetting.
