Understanding the Message “Steering Assist Reduced”

The moment you see this message, it means there is a temporary reduction in the steering assist system’s performance. This means the steering may not be as smooth as before. Below are some possible causes for having reduced steering assist.

1. Sensor Issues

The steering assist system sensor can fail or malfunction over the years of using the vehicles. When this happens, the system cannot detect the various steering parameters; thus, it does not work as it should.

The sensor monitors parameters such as the steering angle, road conditions, and vehicle speed. When this information is not available, the system would not know how best to respond to various driving conditions.

2. Power Supply Problems

A stable power supply is vital for the steering assist system to work effectively. Sometimes you may have low battery power or loose connections.

When such happens, the vehicle will have steering assist reduced so that the remaining power can be used for other core applications.

3. Mechanical failure

The steering assist system works well only if all the components of the system are also in good condition. However, mechanical component failure means the system can no longer function correctly.

Some of the mechanical components that might fail include steering racks, linkages, and power steering pumps. When such components are broken, the steering assist functionality is greatly reduced or completely disabled.
