Diagnostic Trouble Code (DTC) Information BCM-0106

Condition 

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

Courtesy of VOLVO CARS CORPORATION

The steering wheel module (SWM) transmits signals from the steering wheel angle sensor on the control area network (CAN) from where they are retrieved by the brake control module (BCM). A reference signal is calculated using the signals from the wheel sensors, the yaw rate sensor and the lateral accelerometer. The diagnostic trouble code (DTC) is stored if the brake control module (BCM) registers that the signal from the steering wheel module (SWM) is implausible in relation to the reference signal.

Substitute Value 

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