Autel BENZ-38 PIN Adapter — 38-pin to 16-pin OBDII Cable for Mercedes-Benz (Pre-2001) — Durable, OEM-Style

Autel BENZ-38 PIN Adapter converts a Mercedes-Benz 38-pin OBD1 socket into a standard 16-pin OBDII connector so modern Autel scanners can communicate with older Benz models.

Many Mercedes-Benz vehicles built before OBDII became standard (commonly known as OBD1 38-pin Benz models) use a different diagnostic socket that prevents direct connection with contemporary OBDII scan tools. This Autel original BENZ-38 adapter is a purpose-built cable that maps the 38-pin Benz interface to the universal 16-pin OBDII layout, enabling read/clear codes, live data reading, and full system diagnostics when used with compatible scanners.

Will this adapter let my pre-2001 Mercedes talk to my modern scanner?

Yes — when the vehicle has the Mercedes 38-pin female diagnostic socket, this adapter bridges signals to a 16-pin OBDII plug. It does not replace a scanner; it simply provides the correct physical and electrical mating so your OBD2 tool can access engine and system data.

• Works with Mercedes chassis like 107, 124, 126, 201, 202, 210, 208, 170, 129.
• Compatible only with vehicles that have the 38-pin OBD1 female connector — check pin assignment before buying.
• Use with an OBDII-capable scanner (Autel recommended for full function).

What diagnostic functions can I expect when using this Benz 38-pin adapter?

The adapter supports a wide range of scanner functions available through your OBDII tool, including reading and clearing trouble codes, viewing live engine parameters, and performing system-level checks. The specific functions depend on the scanner model and software level you pair with the cable.

• Read/clear fault codes and access live engine data (RPM, speed, temps).
• Full-system diagnostics and bi-directional controls, where supported by your scanner.
• No diagnostic capability by itself — operates only when attached to a compatible scanner.

Is this adapter compatible with my Autel scanner and how reliable is it?

Autel designs this adapter to work with a broad range of Autel scanners for best interoperability; pairing with listed Autel models yields the most consistent results. The cable is built to factory specifications with heavy-duty connectors and industrial-grade materials to ensure stable signal transmission during diagnostic sessions.

• Recommended with models like MK808S, MS906 Pro, MS909, MS919, Ultra and similar Autel tools.
• Durable construction and strict quality control for dependable connections.
• Contact Autel support to verify compatibility prior to purchase if uncertain.

Who is this for: This adapter is aimed at mechanics, restorers, and owners of older Mercedes-Benz vehicles that still use the 38-pin OBD1 interface who want to leverage modern OBDII diagnostic tools. It is ideal for professional shops and DIY enthusiasts who already own or plan to use Autel scanners and need a reliable, factory-specified cable to inspect, diagnose, and service classic Benz models.
