Heavy Duty Diagnostic Tools

Heavy Duty Diagnostic Tools for Trucks, Diesel & Commercial Vehicles

Passenger car scan tools don't cut it on a 24V truck. The protocols are different, the fault codes are different, and the systems — engine management, transmission, hydraulics, body controllers — demand a tool built specifically for commercial vehicle diagnostics.

Autecs supplies professional heavy duty diagnostic tools from Fcar, Autel, and Launch to transport workshops, fleet operators, and heavy vehicle specialists across Australia and New Zealand. Our range covers 12V and 24V diesel engine diagnostics on trucks, buses, trailers, and machinery — with the vehicle coverage and system depth that commercial operators actually need.

━━ Fcar F9S-G ━━

The Fcar F9S-G is the standout heavy duty diagnostic scanner in the Autecs range. Built for workshops that service both passenger vehicles and commercial trucks, it handles 12V and 24V diesel engine diagnostics across all major truck and machinery manufacturers — including Hino, Isuzu, UD, DAF, Mercedes-Benz Trucks, Kenworth, and Caterpillar. Full system diagnostics, bidirectional controls, and reset functions are all accessible through a unified Fcar cloud account, meaning your technician works from one login across every vehicle.

For transport workshops where a truck comes in mid-week and a car comes in next, the F9S-G handles both without switching platforms.

━━ Fcar F7S-W ━━

If your workshop's heavy duty work is primarily light commercial vehicles — vans, utes, and light diesel trucks up to 4.5 tonnes — the Fcar F7S-W covers passenger vehicles and light commercials in a single tool, with the same Fcar cloud platform and bidirectional diagnostic capability. A practical option for workshops that need heavier coverage than a standard passenger car scan tool, without the full 24V commercial vehicle investment.

Workshops already running an Autel MaxiSYS or Launch X-431 platform can extend their existing tool to cover heavy duty vehicles through brand-specific HD upgrade kits. This is the most cost-effective path for workshops where commercial vehicle diagnostics is secondary to passenger car work — you gain truck diagnostic tool capability on your existing hardware without a separate device.

Diesel & Heavy Vehicle Diagnostics Supplied Across Australia and New Zealand

Australia's transport and logistics sector depends on uptime. When a truck goes down, every hour of diagnostic delay has a direct cost. Autecs supplies heavy duty diagnostic tools with Australian warranty and access to our local tech support team — who can assist with vehicle coverage queries, software setup, and fault code interpretation. We serve workshops and fleet operators across Australia and New Zealand, with after-sales support that doesn't require an overseas support ticket.

FAQ

Q1: Do I need a separate scan tool for heavy duty trucks, or can I use my existing passenger car scanner?

A: Most passenger car scan tools do not support 24V commercial vehicle protocols or the proprietary systems used by truck manufacturers. A dedicated truck diagnostic tool — or a heavy duty upgrade module for a compatible platform — is required for reliable heavy vehicle diagnostics. Contact our team to confirm whether your current tool is upgradeable.

Q2: What trucks and machinery does the Fcar F9S-G cover?

A: The F9S-G covers a broad range of commercial vehicles including Hino, Isuzu, UD, DAF, Mercedes-Benz Trucks, Kenworth, Caterpillar, and other major manufacturers. For specific model coverage, contact our tech support team before purchasing.

Q3: Can I use these tools for both diesel cars and heavy duty trucks?

A: Yes. The Fcar F9S-G and F7S-W both cover passenger diesel vehicles and commercial vehicles in a single platform, making them well-suited for workshops servicing a mixed fleet.

Q4: Do you offer after-sales support for heavy duty diagnostic tools?

A: Yes. All tools purchased through Autecs include access to our Australian tech support team and after-sales service covering both Australia and New Zealand.
