DTC C0561 54
WARNING: This page is about a different car, the 2010 GMC Sierra and 2010 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
This diagnostic detects an over temperature condition with 1 of the 12 solenoids due to an extended ABS, traction control and the vehicle stability enhancement system event lasting more than 45 seconds. This does not indicate a failure with the EBCM. If the DTC continues to set under normal conditions, then replace the EBCM.
