Encountering a “Reverse Brake Assist Not Available” error message may catch you off guard. But don’t worry, it’s a common issue with certain vehicles, and there are steps you can take to resolve it.

This message indicates that the reverse brake assist system in your vehicle is currently unavailable, which may affect your ability to safely reverse.

Fortunately, there are several troubleshooting methods you can follow to fix this problem and regain the full functionality of your vehicle’s reverse brake assist system.

Before diving into the potential solutions, it’s essential to understand your vehicle’s reverse brake assist feature.

This advanced technology helps prevent collisions by automatically applying the brakes while reversing when it detects obstacles in the vehicle’s path.

Having a clear understanding of this feature will help you diagnose and resolve the “Not Available” error message much more efficiently.

To address this error message quickly and safely, you’re advised to follow a few key steps, which may include resetting the system, checking for potential obstructions on your vehicle’s sensors, or even having your vehicle inspected by a professional.

Understanding Reverse Brake Assist

Reverse Brake Assist is an advanced safety feature found in some modern vehicles that helps prevent potential collisions while reversing.

When engaged, the system monitors the area behind your vehicle for obstacles and can apply the brakes automatically if it detects any imminent collision.

When engaged, the Reverse Brake Assist System operates the car at speeds between 1-7 mph (2-12 km/h).

If the system detects an obstacle, it can provide a warning through the rear parking aid or cross-traffic alert system before applying the brakes.

However, if you see an error message that says “Reverse Brake Assist Not Available,” it might require some troubleshooting.

One possible reason for this message could be that your vehicle’s doors, liftgate, tailgate, or hood are not fully closed. Drive your vehicle on a straight road for a short period after making sure these are closed.

If you’re using vehicle accessories like a bike rack while reversing, Reverse Brake Assist might misinterpret it as an obstacle and apply the brakes.

In this case, you can turn off the Reverse Brake Assist feature by following these steps:

  1. On your in-vehicle screen, go to Settings
  2. Select Driver Assistance
  3. Tap Reverse Brake Assist
  4. Toggle the feature to Off

If the problem persists, you can try resetting the brake assist system by doing the following:

  1. Park your car in a safe location and turn off the engine
  2. Open the car hood
  3. Unscrew the battery’s positive terminal and remove the cable
  4. Get inside the driver’s seat, press the brake pedal for a minute, then release the pedal
  5. Reconnect the battery.

If the error message still appears after trying these solutions, consult your vehicle’s manual or seek assistance from a professional mechanic to diagnose and fix the problem.

Causes of ‘Reverse Brake Assist Not Available

Sensor Issues

One possible cause of the ‘Reverse Brake Assist Not Available’ message is faulty sensors.

The system relies on sensors to detect obstacles behind your vehicle.

If any of these sensors are malfunctioning or obstructed by dirt, debris, or ice, the reverse brake assist system might struggle to work correctly.

To fix this issue, regularly check and clean your sensors to ensure they function properly.

Rear Camera and Network Interruption

Another common issue is network interruption or problems with the rear camera.

If your rear camera is obscured, it might trigger the ‘Reverse Brake Assist Not Available’ message.

An interruption in your vehicle’s network, for example, in 2021 Mustang Mach-E and F-150 vehicles, can also cause this warning. This happens because the steering center in the vehicle gets reset.

To rediscover the center, drive for a few minutes at a slow speed, about 18 mph (30 km/h) on a flat, straight road. The car will rediscover the steering center and remove the reverse brake assist not available warning will go away.

Software and Module Programming

Occasionally, the ‘Reverse Brake Assist Not Available’ message might be due to software and module programming issues.

In some cases, module programming can be completed improperly or encounter some issues during the process.
