Diagnostic trouble code (DTC) information

Condition 

Fig 1: Identifying Brake Control Module (BCM) & Steering Wheel Angle Sensor

Courtesy of VOLVO CARS OF NORTH AMERICA.

The control module for the steering angle sensor transmits a signal via the Control area network (CAN) which indicates to the brake control module (BCM) whether the function of the steering wheel angle sensor is correct or not.

Diagnostic trouble code (DTC) BCM-0115 is stored if the brake control module (BCM) registers that the signal from the steering angle sensor is missing.

The diagnostic trouble code (DTC) can be diagnosed when the ignition is switched on.

Substitute Value 

• Traction control is blocked
• Stability control is blocked
• Active yaw control is blocked.

Possible Source 

• Disruption or open-circuit on the Control area network (CAN)
• The steering angle sensor is not connected on the Control area network (CAN)
• Internal fault in the steering angle sensor.
