Autel 16-Pin OBD2 Main Test Cable — 3-Row Scanner Connector, Extra-Long Lead for Diagnostics

Autel's Original 16-pin 3-row OBD2 Main Test Cable is a purpose-built diagnostic lead that links compatible Autel scanners to a vehicle's OBDII port for data transfer and testing.

This genuine Autel main test cable replaces the standard short lead with an extra-long connection, giving technicians more freedom of movement while troubleshooting vehicles. Engineered specifically for select Autel tablet and handheld diagnostic units, the cable provides a secure 3-row plug for the scanner and a conventional 16-pin OBDII connector for the vehicle data link connector (DLC). It is designed for data transmission and diagnostic workflows such as reading/erasing codes, freeze-frame capture, active tests and ECU information retrieval when paired with a supported Autel device.

Which Autel scanners work with this 3-row OBD2 main test cable?

The cable is compatible only with a defined set of Autel models that use a 3-row scanner-side connector. Confirm your unit before purchasing to avoid incompatibility. It is not a universal lead and will not function with many handhelds or non-Autel scanners.

• Compatible examples: MS908P, MS908S Pro, MS908S PRO II, MK908 PRO, MK908 Pro II.
• Also works with: MS908CV, MS908CV II, Elite, Elite II, MS909, MS919, Ultra Lite, Ultra.
• Supported IM series: IM608 PRO, IM608 PRO II, IM608S, IM608S II.
• Check your scanner model against this compatibility list before ordering.

What vehicles and diagnostic functions can I perform with this cable?

When connected to a compatible Autel scanner, the cable enables a full suite of diagnostic operations supported by the scanner software. It transfers vehicle data and allows access to systems for troubleshooting and programming functions the scanner supports.

• Read and clear diagnostic trouble codes (DTCs) from vehicle ECUs.
• Retrieve freeze frame and live data streams for analysis.
• Execute active tests, bi-directional commands, and ECU information queries.
• Supports diagnostic-level programming and coding when your Autel tool provides those features.

How is this cable different from a standard OBDII lead?

This Autel main test cable is longer and has a scanner-specific 3-row connector rather than two identical 16-pin ends found on common extension leads. The extended length reduces the need to work cramped inside the vehicle and lets you position the scanner conveniently outside the cabin during complex jobs.

• Extra-long run for easier access during repairs and programming.
• 3-row scanner interface ensures a secure fit to supported Autel devices.
• Durable 16-pin vehicle plug designed for repeated diagnostic use.
• Plug-and-play connection with screw-tightened interface for reliability.

Are there important compatibility exclusions or cautions?

Yes—this lead is model-specific and excludes many Autel handhelds and other-brand scanners. It’s not suitable for FCA vehicles requiring the Chrysler 12+8 interface; select a Chrysler-specific cable for those cars. Always verify both scanner and vehicle requirements before purchase.

• Not compatible with many Autel handheld lines (e.g., MS309, AL519, AL619, ML519, ML629, TS series).
• Does not fit MK808-series, MX808-series, MP808-series, DS708/DS808 variants, MS906, IM508 models.
• Not intended for non-Autel scanners or generic OBD tools.
• For Chrysler/Dodge/Jeep/FIAT/Alfa Romeo FCA vehicles, use a Chrysler 12+8 cable instead.

Who this is for: This long Autel 16-pin 3-row main test cable is made for professional technicians and experienced DIYers who own one of the supported Autel diagnostic tablets or IM/Elite series units and need a reliable, extended lead for thorough in-vehicle testing. If your scanner model is listed in the compatibility section and you perform advanced diagnostics, coding, or ECU-level work, this cable simplifies access and maintains a stable data connection. If your device isn’t on the compatibility list or you work primarily with FCA vehicles requiring a specialized interface, choose the correct Autel cable variant or consult Autel support before buying.
