CTobd OBD2 12+8 SGW Programming Cable for FCA Vehicles - Red adapter for Security Gateway Bypass, Diagnostics & Coding

The CTobd OBD2 12+8 programming cable bypasses FCA Security Gateway modules so diagnostic tools can fully communicate with 2013–2020+ Chrysler, Jeep, Dodge, Fiat, Ram and Alfa Romeo vehicles.

This specialized red CTobd adapter links the factory Security Gateway Module (SGM) to your scanner, restoring direct communication for advanced diagnostics, coding and service functions on modern FCA platforms. It’s designed for technicians and advanced DIYers who use Maxisys, DS/Autel, Launch and similar scan tools that require access past the vehicle’s security gateway to read/clear codes, run active tests, view live data and perform adaptations.

How does this cable let my scanner talk to vehicles with a Security Gateway?

When a vehicle includes an SGM, direct OBD2 requests can be blocked. The CTobd 12+8 cable plugs into the two SGM connectors (12-pin and 8-pin) and routes signals to your scanner’s 16-pin OBD port, effectively bypassing the gateway so diagnostic commands reach the control modules.

• Plugs into SGM 12-pin and 8-pin connectors, relocating signals to OBD2 16-pin.
• Works with scanners and Bluetooth OBD interfaces for flexible setups.
• Re-establishes reading/clearing of DTCs, active tests and live data streams.

Which scan tools and tablets are compatible with this CTobd adapter?

This 12+8 cable was built to work with many professional handhelds and tablets that require gateway bypass for FCA vehicles. It’s compatible with Autel Maxisys and DS series, Launch X431 equipment, X300 DP Plus and many key programming tablets and pads.

• Compatible with MS906BT+, MS908, Maxisys Elite, IM608 and related Autel models.
• Works with Launch X431 V series, X300 DP Plus and X100PAD family tablets.
• Suitable for Key Tool Plus Pad and similar diagnostic devices supporting bypassed OBD access.

What vehicle years and models need the 12+8 Programming Cable?

Many FCA models introduced the Security Gateway between 2013 and 2020, with full coverage of new vehicles by 2020. The CTobd cable covers RAM, Fiat, Alfa Romeo, Chrysler, Dodge and Jeep lines that use the SGM, including specific model-year ranges noted by manufacturers.

• 2013+ RAM Promaster, 2015+ Fiat 500X and RAM Promaster City.
• 2016+ Jeep Renegade; 2017+ Alfa Romeo Giulia, Jeep Compass and Cherokee.
• 2018+ many Jeep, Ram, Dodge and Chrysler models (Wrangler JL, Charger, Challenger, Pacifica, 300, Durango, Grand Cherokee, Journey).
• 2019+ and 2020+ models: increasing SGM prevalence and full adoption by 2020.

What diagnostic tasks become possible after bypassing the gateway?

With the gateway bypassed, your scan tool can perform system-level diagnostics and service procedures that are otherwise blocked. This includes reading manufacturer-specific data, commanding actuators during active tests, performing TPMS relearn and executing coding or adaptations when used with compatible software.

• Read and clear manufacturer codes, not just generic OBDII faults.
• Run active tests and view both generic and OEM live data streams.
• Perform TPMS OBDII relearn, ADAS-related calibrations (with proper software) and module coding/adaptations.

Who is this for? The CTobd 12+8 programming cable is aimed at automotive technicians, independent repair shops and experienced DIYers who use professional diagnostic tablets and scanners and need reliable access to FCA vehicle systems blocked by the Security Gateway. It’s ideal when your scanner displays messages like “DEVICE UNABLE TO COMMUNICATE WITH THE CONTROL UNIT” and you need to restore full tool functionality for advanced diagnostics or programming.
