The Buick C0561 fault code indicates a problem with the Electronic Brake Control Module (EBCM).
Symptoms include the AntiLock Brake System (ABS) Warning Light and Engine Light being ON.
The issue is not with the EBCM itself, so other codes should be checked.
To fix, inspect the wiring harness, connectors, and components for damage or corrosion.
This issue should be addressed promptly to ensure safe braking operation.

Fix for Buick c0561
Address the issue by diagnosing and repairing the Electronic Brake Control Module (EBCM) internal malfunction.
- To fix C0561, first, review the possible causes and visually inspect the wiring harness and connectors for any damage.
- Check the connector pins for signs of being broken, bent, pushed out, or corroded.
- Next, perform a diagnostic scan tool check to identify the specific module that is causing the issue.
- Once identified, reset or reprogram the module if possible.
- If the issue persists, consider replacing the faulty module with a new one.
Description for Buick c0561
C0561 in a Buick indicates a problem with the Electronic Brake Control Module.
Code C0561 for a Buick indicates that there is a problem with the Electronic Stability Control (ESC) system.
This code is triggered by the Electronic Brake Control Module (EBCM) when it detects an issue with the ESC system.
The ESC system helps to improve vehicle stability and prevent skidding during sudden maneuvers.
When this code is set, it typically points to a fault in the ESC system, such as a malfunctioning wheel speed sensor, steering angle sensor, or an issue with the ESC module itself.
That fault code is a turning point. If repair costs are climbing and your current loan feels like it’s holding you back, this is the time to plan ahead. The free Car Loan Payment Tracker helps you see how quickly you can pay off what’s left—and start preparing, with confidence, for your dream car.
Tech Notes for Buick c0561
For Buick C0561, check for issues with the Electronic Brake Control Module (EBCM) communication circuit.
When dealing with fault code C0561 in a Buick, it typically indicates an issue with the Electronic Brake Control Module (EBCM).
To diagnose this code effectively, you can start by checking the power and ground connections to the EBCM using a voltmeter.
Ensure that there is proper voltage supply and ground connection to the module.
Next, use a scan tool to communicate with the EBCM and check for any stored codes related to wheel speed sensors or communication errors.
Verify if the EBCM is responding over the Controller Area Network (CAN) network.
If there are communication issues, inspect the wiring harness and connectors for any damage, corrosion, or loose connections.
Additionally, it’s essential to inspect the wheel speed sensors and tone rings for any physical damage or contamination that could be causing erratic signals to the EBCM.
Ensure that the wheel speed sensor signals are within specifications when the wheels are rotated.
If all wiring, connectors, and components check out, reflashing the EBCM with the latest software may be necessary to resolve the C0561 fault code.
Reflashing can sometimes correct software glitches or communication errors within the module.
By following these diagnostic steps and utilizing a voltmeter, scan tool, and visual inspection techniques, you can
