  • Requires compatible OBD2 scanner
  • Not reversible connection
Specification:
Connector Types 9-pin J1939 male, 6-pin J1708 male, 16-pin OBD2 female
Compatibility Supports J1939 and J1708 protocols for heavy-duty commercial vehicles
Cable Length 30 cm (11.8 inches)

Supported Devices Compatible with Autel MaxiSYS MS909CV, MS906CV, MS908CV, MS908CV II diagnostic scanners
Warranty 1-year warranty with 30-day full refund or replacement policy

Many folks think that all OBD adapters are basically the same, just different brands and connectors. But I quickly learned that when it comes to heavy-duty trucks, a standard OBD2 connector just isn’t enough.

This Autel adapter is a game changer because it bridges the gap between heavy-duty J1939 and J1708 protocols and the regular OBD2 port. I tested it on a diesel truck with a 9-pin J1939 port and a 6-pin J1708 port, and it plugged in seamlessly.

It’s compatible with Autel’s CV scanners, which are designed for heavy-duty diagnostics, so I’d recommend pairing it with one of those for best results.

However, keep in mind that your OBD2 device must support both J1939 and J1708 protocols, or this adapter won’t do the heavy lifting alone. Also, it’s not suitable if you need a reverse connection—this is a male-to-female adapter only.

Still, for anyone troubleshooting commercial vehicles, this adapter packs a punch and makes diagnostics much easier.

Overall, it’s a reliable, plug-and-play solution that saves you time and frustration when dealing with complex truck wiring. Plus, Autel’s customer support and warranty give peace of mind for long-term use.
