MASERATI LEVANTE Radar Sensor AAC

For the Maserati Levante, the part numbers 670154291 and 0203303245 identify the Front Radar Sensor for the Adaptive Cruise Control (ACC) system. This is a critical component of Maserati’s Advanced Driver Assistance Systems (ADAS), often referred to in technical catalogs as the “Distronic” or “ACC” sensor.

1. Technical Breakdown

• OEM Part Number: 670154291 (Maserati Genuine)

• Manufacturer Number: 0203303245 (Bosch)

• Primary Function: Measures the distance and relative speed of vehicles ahead to maintain a set following distance.

• Key Features: Enables the Stop & Go function, allowing the Levante to come to a complete halt in traffic and resume driving autonomously if the stop is brief.

2. Location and Installation

In the Maserati Levante, this radar sensor is typically located in the front grille, positioned centrally behind the Trident logo or slightly offset depending on the specific trim and year.

Technical Note: In 2026, many Levante models feature a “Radar Trim” or specialized grille section that allows the millimeter-wave radar to pass through without interference. If the front Trident emblem is cracked or heavily obscured by mud/ice, the sensor will likely trigger a “Cruise Control Disengaged” error.

3. Compatibility

While this specific part number is primarily listed for the Levante (2017–2024+), it is often shared across the Maserati lineup due to the common electrical architecture:

• Maserati Ghibli (2017+ models with ACC)

• Maserati Quattroporte (2017+ models)

4. Calibration Requirements (Important)

If you are replacing a faulty or crashed sensor with a new or used unit, a static and/or dynamic calibration is mandatory:

• Static Calibration: Uses a specialized ADAS target board (usually a Doppler generator or a physical reflector) placed in front of the vehicle at a specific distance and height.

• Dynamic Calibration: Involves a “learning drive” where the technician drives the car on a highway with clearly defined markings for the sensor to calibrate itself against surrounding traffic.

• Coding: You may need to perform a “Proxy Alignment” using Maserati’s ODIS or high-end diagnostic tools (like Leonardo or Autel with Maserati software) to marry the new sensor to the vehicle’s CAN bus system
