Which connector your truck already has
The HD601 talks to 12V and 24V heavy-duty trucks, and the brand list covers most of the big North American names, including Freightliner and Peterbilt along with the other major makes. It also reads diesel engines from Cummins, Detroit and PACCAR, so we'd consider it a sensible fit for owner-operators and small fleets checking their own equipment.
You need to match the physical port before anything else. The scanner ships with 6, 9, and 16-pin connectors, and those cover the common interfaces on commercial vehicles.
Coverage changes with model year, system, and configuration, so confirm your specific truck appears in the current vehicle list. The same tool reads OBD2 on light-duty cars, which is handy if you keep a pickup or service van alongside the heavy iron.

What it will not do
This is a scan and information tool, not a repair device. It reads and clears fault codes, shows live data and freeze frame data, and runs quick and full scans across engine, transmission, ABS, and other systems.
A code tells you which system needs attention. It does not tell you a part is safe to keep driving on, and a cleared light is not proof the fault is gone. Treat the output as a starting point for diagnosis, then let a technician confirm anything serious.
The HD601 identifies fault areas. It does not diagnose whether the vehicle is safe to operate.
The offer and what it is measured against
- Amazon price
- $135.99
- Customer rating
- 4.1
- Customer reviews
- 304
- Typical price over 90 days
- $156.18
- Difference
- $20.19 (13 percent)
At $135.99, this sits $20.19 under the typical price over the last 90 days of $156.18. That is roughly 13 percent below the recent average, and the current price matches the all-time low for this listing.
The rating sits at 4.1 from 304 reviews, which is reasonable for a tool in this bracket. If you have been waiting for the HD601 to dip, this is the level it has dipped to before.
Power, updates, and where it lives
The scanner draws power from the vehicle through its diagnostic cable, so plan on plugging in with the ignition in the position your truck needs for module communication. Keep the cable run in mind if your port sits behind a panel or under the dash.
Updates are free for life, which keeps vehicle coverage current as new models and software arrive. You will need a computer and an internet connection for those updates, so check that before you rely on newer coverage.
The DTC library works offline, including manual SPN and FMI lookups, which matters when you are road-side without signal. The unit itself is a handheld, so check that the display is readable in the cab lighting you actually work in.
Who should buy the ANCEL HD601
Buy it if you run heavy trucks and want one handheld that covers HDOBD protocols, engine, transmission, and ABS faults, plus OBD2 on your light vehicles. The 6, 9, and 16-pin connectors and free updates make it a practical long-term pick for a shop or a single rig.
Skip it if you only need a basic code reader for a passenger car, or if your truck's coverage is not listed for your model year and configuration. Before checkout, pull your truck's diagnostic port and confirm it matches one of the included connectors.
