How to Reset and Repair Adaptive Cruise Control in Your Mercedes

The Mercedes-Benz cars have always been associated with top-notch technology that makes the process of driving much more pleasant and brings relief to the drivers. The Adaptive Cruise Control (ACC) is one of the most outstanding features that can give you great relaxation while cruising on the highway at your required speed and distance from the other vehicles on the road.

How Does Adaptive Cruise Control Function in Your Mercedes?

Sensors & Cameras — They always watch what lies ahead on the road such as other vehicles or potential obstacles in the way.

ECU (Electronic Control Unit) — The component where all information from the sensors is processed, monitoring the vehicle’s speed and able to brake or accelerate independently to maintain a safe distance from other vehicles.

Automatic Changes — Capable of changing speeds or even stopping entirely depending upon the current traffic conditions.

Why is your Mercedes’ ACC malfunctioning?

Blockages or Sensor Alignment Issues — For ACC to work optimally it needs perfect ‘eyesight’ from its radar sensors and cameras. Dust, mud, dirt, snow, ice and bugs are among the factors that may interfere with the sensors and result in malfunction or error messages. Even minor dents or bumps sustained while parking can affect the alignment of the sensors.

Software Problems — ACC is a sophisticated computer program whose smooth operation depends on the software used. It is common for outdated software or corrupted files to cause ACC to malfunction.

Electrical or Wires Problems — Disconnection or damage to the wires connecting the sensors to the ECU and vice versa may disrupt their communication and cause the ACC to malfunction.

Faulty Parts — Radar sensors, cameras and the ECU are some of the components that may cause ACC malfunction. This is because these parts are prone to failures when exposed to water or sudden power surges.

Aftermarket Installations — Changes to any of these parts such as grills or bumpers or front windshields require ACC calibration.

Diagnosis and Resetting Process of ACC

Look for Dashboard Indicators

If you have a Mercedes vehicle then it should indicate certain faults in its dashboard such as “DISTRONIC Plus Inoperative,” “Radar Sensor Blocked,” etc. You should be aware of them because they provide useful information.

Cleaning of the Sensors and Camera

You should inspect the sensors housing which is typically installed in the front grille of your car as well as the camera housings. Carefully clean them with a soft and damp cloth from any dust, snow, ice or other contaminants. Do not use any abrasive materials.

Power Cycles

In some cases, power cycling your vehicle may help you fix the problem. Therefore, you should turn off your Mercedes, wait several minutes and then turn it on again. It helps reset minor faults in your vehicle’s electronics.

Disconnection of the Car Battery

Finally, you should consider disconnecting the battery of your car. Make sure you disconnect the negative terminal first and then leave the battery disconnected for 10 to 15 minutes.

When Should You Have Your Mercedes-Benz System Repaired and Calibrated?

• Your radar sensors and cameras can be accurately aligned if your car has been in some kind of collision whether major or minor.
• In case of any part being defective or malfunctioning then it’s likely a radar sensor, camera or ECU so the best thing to do would be to replace it with an original Mercedes-Benz part.
• If you have undergone any changes to your car’s body or windshield then it may mean that your ACC sensors will need professional recalibration.

Maintaining the Reliability of Your ACC System

• Remember to clean your sensors and cameras frequently.
• Always engage with authorized dealers or qualified technicians for any software updates or electrical repairs.
• Refrain from making any aftermarket adjustments that might affect your sensors and cameras.
• Never overlook any alerts shown on your dashboard to avoid possible future problems.
