C0561 traction control code

Fix code C0561 traction control code

Code C0561 comes in two forms.

C0561-71 System disabled Information stored invalid serial data received
C0561-72 System disabled Information stored alive counter incorrect.

C codes are considered “chassis” code. This particular code is for GM and relates to the traction control system. The traction control system gets its data from the ABS system. When it detects one wheel spinning faster than the others, or one wheel locking up, it activates the traction control system. Depending on the generation of traction control, the system will activate the ABS brakes to reduces spinning, or, in later models can actually reduce engine power. Late model systems include yaw sensors and steering position sensors to detect the difference between the driver’s intention from the steering wheel and the actually direction the vehicle is moving.

In the case of this GM code, the electronic brake control module (EBCM) 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.
