What does code c0561 mean on the chevy silverado?

Code C0561 on the Chevy Silverado is alerting you that there is a problem with the electronic brake control module (EBCM). This is what disables the traction control system or the vehicle stability enhancement system. The code means the EBCM is receiving faulty data from other modules or is faulty itself.Electronic braking systems are controlled by the electronic brake control module or EBCM for short. The EBCM reads all of the braking system's sensors and activates the ABS or traction control system when it detects it is necessary.The most common symptom of a problem with the EBCM is an illuminated ABS Light. The EBCM is often tied into, if not the main control unit for the ABS. When it fails or has any issues, it will set off the ABS Light to alert the driver of an issue.
