Autel J1939 to OBD2 Adapter Cable Type 2 Green 9‑Pin + 6‑Pin Y‑Cable — 16‑Pin OBD2 Conversion, Rugged 20 AWG

Autel's Original J1939-to-OBD2 Type 2 adapter is a 2-in-1 Y-cable that converts truck 9-pin J1939 (Type 2 green) and 6-pin J1708 ports to a standard 16-pin OBD2 connector for compatibility with OBD diagnostic tools.

This rugged Autel adapter cable bridges heavy-duty vehicle diagnostic ports and consumer-grade OBD2 scanners, allowing compatible diagnostic devices to access powertrain, chassis, and body ECU data over J1939 or J1708 networks. It is a hardware-only interface: whether diagnostics succeed depends on the vehicle’s supported protocols and the scanner’s capabilities. The cable itself guarantees reliable physical conversion and is built to withstand workshop use.

How does this adapter let my OBD2 tool talk to a diesel truck?

The Y-cable converts the truck’s round 9-pin J1939 Type 2 (green) and 6-pin J1708 ports into a standard 16-pin OBD2 plug, exposing the vehicle’s diagnostic bus to any compatible scanner. It supports both high-speed and low-speed heavy-duty communication lines so a wider range of data is available when the vehicle and tool support those protocols.

• Converts Type 2 green 9-pin J1939 and 6-pin J1708 to 16-pin OBD2
• Works with scanners that support J1939/J1708 over an OBD2 connector
• Compatible with high-speed and low-speed ports for broader coverage
• Physical conversion only — vehicle and tool protocol support still required

What are the cable’s build details and dimensions?

Autel designed this cable with workshop durability in mind: heavy-gauge 20 AWG wiring and fully overmolded connectors resist abrasion and corrosion. The overall cable length is compact for ease of handling, and connector housings are sized for secure mating with commercial heavy-duty ports.

• Total cable length approximately 41 cm (allow small measurement variance)
• Standard 16-pin OBD2 male housing: ~6.2 × 4.5 × 2.15 cm
• Green Type 2 connector: ~6.84 cm length, ~4 cm diameter
• Gray Type 1/black 6-pin compatible connector: ~6.8 cm length, ~3.68 cm diameter

Will this adapter survive daily shop use and heavy environments?

The cable uses robust materials and thick conductors to maintain signal integrity and resist physical wear. All connector interfaces are overmolded for strain relief and environmental protection, so the adapter remains flexible and reliable across routine diagnostic sessions.

• 20 AWG thick wires for stable power and data transmission
• Overmolded connector bodies for durability and corrosion resistance
• Designed to stay flexible while resisting shop abrasion
• Compatible with both high- and low-speed heavy-duty ports

What warranty and support come with the Autel adapter?

Autel backs the adapter with a customer-friendly return and warranty policy plus technical support to resolve fitment or usage questions. If the cable has manufacturing defects, the product qualifies for replacement or refund within the stated policy period.

• 30-day replacement or full refund policy
• 1-year limited warranty for defects in materials and workmanship
• 24/7 technical support via the seller contact email
• Note: Adapter provides a physical interface only, not protocol translation beyond vehicle/tool capabilities

Who is this for: technicians, fleet mechanics, and owners of heavy-duty diesel trucks who use consumer or universal OBD2 diagnostic tools but need a physical interface to access J1939 or J1708 networks. Confirm that your vehicle supports J1939/J1708 and that your diagnostic device recognizes those protocols when presented through a 16-pin OBD2 connector before purchasing.
