The Autel Jeep Adapter, also known as the Chrysler 12+8 diagnostic cable, is an essential tool for diagnosing and servicing late-model Chrysler, Dodge, Jeep, Ram, Fiat, and Alfa Romeo vehicles. These vehicles utilize a Security Gateway Module (SGM) that restricts access for aftermarket scan tools, often limiting functionality to only reading Diagnostic Trouble Codes (DTCs) and viewing basic data. The Autel 12+8 adapter bypasses the SGM, enabling full diagnostic and service capabilities.
Why You Need an Autel Jeep Adapter
Most 2018 and newer Fiat Chrysler Automobiles (FCA) vehicles incorporate an SGM to enhance vehicle security. While beneficial for preventing unauthorized access, the SGM poses a challenge for mechanics using aftermarket diagnostic tools. Without the Autel Jeep adapter, your scan tool might display a “Device Unable to Communicate with the Control Unit” message, preventing crucial bidirectional control functions. The SGM’s location varies but is commonly found in the passenger-side kick panel, near the glove box, or behind the radio.
This adapter allows your Autel MaxiSys scanner to perform advanced functions beyond basic DTC reading. It enables crucial tasks such as:
- Reading and Clearing Codes: Diagnose and resolve issues by accessing and clearing DTCs.
- Performing Active Tests: Conduct component tests to pinpoint malfunctions.
- Viewing Live Data: Monitor real-time sensor data for comprehensive diagnostics.
- Performing TPMS OBDII Relearn: Efficiently program Tire Pressure Monitoring System sensors.
- Coding and Adaptation: Customize vehicle settings using advanced MaxiSys features.
- ADAS Calibrations: Perform Advanced Driver-Assistance Systems calibrations with compatible MaxiSys software and hardware.
