Diagnostic Trouble Code (DTC) Information BCM-0076

Condition 

Fig 1: Identifying Brake Control Module (BCM)

Courtesy of VOLVO CARS CORPORATION

The brake control module (BCM) is programmed at the factory with software for several car models. During the first ignition cycle, the control module reads the vehicle configuration data from the central electronic module (CEM). The brake control module (BCM) then configures itself according to the car model and equipment.

The diagnostic trouble code (DTC) can be stored if

• a brake control module (BCM) is installed that has previously been used in another car
• software adapted to a different type of brake system (for example STC software in a DSTC vehicle) has been downloaded into the brake control module (BCM)
• a central electronic module (CEM) is installed that has previously been used in another car.

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.
