Autel 12+8 OBD2 Adapter for Chrysler Dodge Jeep Fiat Alfa Romeo — 2018+ SGW Bypass Cable, 16‑Pin OBDII Access

Autel 12+8 OBD2 adapter for Chrysler bypasses the factory Security Gateway so your OBD2 scanner can communicate with 2018+ Chrysler, Dodge, Jeep, Fiat and Alfa vehicles.

Modern FCA vehicles include a Security Gateway Module (SGM) that blocks many third-party diagnostic tools. The Autel 12+8 OBD2 cable provides a direct hardware path around that gateway, enabling scanners and Bluetooth OBD interfaces to access vehicle networks for diagnostics, service functions, and code reads on compatible models from 2018 onward.

How do I install the Autel 12+8 OBD2 bypass cable?

Installation is straightforward and done in four clear steps: locate and unplug the SGW module's 12-pin and 8-pin connectors, attach the Autel adapter to those ports, then plug the 16-pin end into your scanner or pair a Bluetooth interface. No vehicle wiring modifications are required.

• Find and unplug the SGW 12-pin and 8-pin connectors.
• Attach the Autel 12+8 adapter to the two SGW ports.
• Connect the adapter's 16-pin OBD2 plug to your scanner or OBD Bluetooth interface.
• Power the scanner or pair the Bluetooth interface to start diagnostics.

Which vehicles and scanners will this adapter work with?

The Autel 12+8 cable is built for FCA platforms and supports Chrysler, Dodge, Jeep, Fiat and Alfa models from 2018 and later that use the 12+8 SGW configuration. It is compatible with all standard OBD2 scanners and Bluetooth OBD interfaces that expect a 16-pin connection.

• Compatible years: 2018 and later FCA vehicles with a 12+8 SGW connector.
• Brands: Chrysler, Dodge, Jeep, Fiat, Alfa Romeo.
• Works with wired OBD2 scanners and Bluetooth/Wi‑Fi OBD adapters.
• Enables full system diagnostics and service functions accessible via your scanner.

What diagnostic functions can I perform once bypassed?

With the SGW bypass in place, your scanner gains access to vehicle network modules for comprehensive diagnostics: read and clear fault codes, view live data, perform system tests, and run service or maintenance routines the scanner supports. The cable itself does not add software features; available functions depend on your scanner's capabilities.

• Read/clear DTCs across engine, ABS, airbag, transmission, and body modules.
• View live sensor data and PID streams if the scanner supports them.
• Run supported service resets and relearns via your diagnostic tool.
• No software install needed—just connect your existing scanner.

Who is this for: The Autel 12+8 OBD2 adapter is aimed at professional technicians, independent repair shops, and knowledgeable DIYers who routinely service FCA vehicles with SGW protection. If you own a compatible scanner and need unrestricted diagnostic access to 2018+ Chrysler, Dodge, Jeep, Fiat or Alfa cars, this adapter simplifies access without permanent vehicle modifications.
