The AAS fault in the Mercedes-Benz G-Class indicates an issue with the wheel speed sensor. The sensor or its connector may have become detached. The sensor is located in the steering knuckle of the front and rear wheels, inserted at a 45-degree angle. You can check if the connector has come loose by disassembling the ball joint. This fault can prevent the vehicle from moving because the speed sensor transmits signals to the central control unit along with the throttle electronic signals. It requires repair at an authorized 4S dealership to clear the fault code. Additional information: 1. Function of wheel speed sensor: The wheel speed sensor measures the rotational speed of the vehicle's wheels. Common types include magnetic wheel speed sensors and Hall-effect wheel speed sensors. 2. Mercedes-Benz G-Class engine: The standard G-Class model features the V8 engine from the S-Class, representing the latest technological advancements. It delivers peak power of 184 kW/250 hp at over 1,700 rpm and torque of 560 N·m, making it one of the most powerful passenger car diesel engines in the world.
