What are the potential symptoms of the brake control module issue for drivers?

Question

Accepted Answer

Drivers may experience a stiff brake pedal and loss of electronic braking support systems.

Customers with affected Volvo vehicles may encounter a stiff brake pedal and the loss of electronic braking support functions, such as Antilock Brake System (ABS), Electronic Stability Control (ESC), and traction control. While these electronic systems may cease to function, the vehicle's braking capabilities will remain operational through manual application of the brake pedal, which will revert to the car's hydraulic system. Drivers will be alerted to the issue via the driver information module (DIM) should it occur.
Loss of Electronic Braking Support

The primary symptom reported is the loss of electronic braking support functions. This includes the potential failure of the Antilock Brake System (ABS), Electronic Stability Control (ESC), and traction control systems. These advanced systems are designed to enhance vehicle safety and control, and their malfunction can significantly impact the driving experience.
Impact on Advanced Driver Assistance Systems

Beyond core braking functions, the Brake Control Module (BCM) issue can also affect other advanced driver assistance system (ADAS) features. This may include the disabling of adaptive cruise control and one-pedal driving capabilities. These features rely on precise electronic control, and the BCM fault can lead to their inoperability.
Continued Manual Braking Capability

Despite the loss of electronic support, the vehicle will retain its ability to be braked manually. If the BCM issue manifests, the driver can still apply the brakes using the brake pedal. The vehicle will then rely on its fundamental hydraulic braking system to slow down and bring the car to a complete stop, ensuring a basic level of braking performance remains.
Driver Notification System

Volvo has implemented a warning system to alert drivers if the BCM issue occurs. The driver information module (DIM) will display a notification, informing the driver of the problem. This ensures that drivers are aware of the potential compromise in their vehicle's electronic braking systems and can take appropriate action.
