ANCEL AD310 Classic Enhanced Universal OBD II Scanner
The AD310 is a compact, entry-level OBD II scanner popular for quick fault code reading and clearing. It supports emission system codes, freeze frame data, and I/M readiness checks, making it suitable for everyday troubleshooting. Its design emphasizes portability—weighing about 12 ounces with a 2.5-foot cable and clearly labeled buttons for intuitive use. Users benefit from fast, direct access to diagnostic trouble codes (DTCs) and the ability to clear MIL/CEL alerts after repairs. No battery or charger is required; power is drawn from the vehicle’s OBDII port, enabling easy roadside checks.
Key considerations:
- Pros: Simple operation, reliable for common codes, portable design, clear results on a bright display.

Its straightforward interface makes it a solid option for owners who want a fast, offline reference to vehicle faults.
Key considerations:
