The C codes represent diagnostic issues which are classified as “chassis”. C0561 Chevy diagnostic GM code is associated with problems related to the traction control system.
When the Powertrain control module (PCM) or body control module (BCM) detects a condition that prevents engine traction control.
It sends a serial data message to the engine control module (EBCM) to deny torque reduction. Typically, the PCM or BCM will set a DTC, and the EBCM will set this DTC.
In this post, we will help you understand how the C0561 Chevy code works, the symptoms, and how you can fix related issues.

Understanding the C0561 Code on a Chevy
C0561 is a system code that involves the traction control system, which receives data from the ABS.
When the ABS 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 reduce spinning or, in later models, can reduce engine power.
Terminologies You Need to Know in Understanding C0561
1. Electronic Brake Control Module (EBCM)
This is a device that regulates a vehicle’s braking system. It collects input from sensors throughout the car and determines how much braking force to deploy.
2. Engine Control Module (ECM)
The ECM controls fuel injection, ignition timing, and other engine processes to improve engine performance.
3. Instrument Panel Cluster (IPC)
This instrument provides you with information regarding the state of the vehicle’s systems. The cluster often includes a speedometer, tachometer, fuel gauge, and numerous warning lights.
4. Body Control Module (BCM)
This Control Module takes input from sensors throughout the vehicle and provides commands to actuators that control the equipment. It also monitors other systems such as the engine, brakes, and airbags.
5. Anti-lock Brake System (ABS)
This is a vehicle technology that helps to prevent the wheels from locking up during braking. This assists the driver in maintaining control of the car.
6. Transmission Control Module (TCM)
This module collects sensor input about the vehicle’s speed, engine rpm, and gear position and uses this data to calculate how much torque to transmit to the transmission. The TCM also modifies the shift points of the transmission to match the driving conditions.
Symptoms of C0561 Chevy
1. Decrease Engine Power
Reduced engine power is one of the most typical indications of C0561 traction problems. Because of the diminished engine power, the vehicle’s acceleration and peak speed are both lower than typical.
2. ABS Light Comes On
If the ABS light on your dashboard illuminates, it’s time to check for traction control issues. It is a major symptom that a variety of issues can cause.
3. Check Engine Light Activated
A traction problem is one of the possible explanations for this light turning on. If you have a traction problem, you may notice that your vehicle does not respond well to acceleration or braking and may even slip when attempting to make a turn. If the engine light comes on, you may be experiencing traction problems.
Causes of the C0561 Chevy Code
1. Damaged EBCM
In most modern automobiles, the electronic brake control module (EBCM) is in charge of controlling the braking and stability control systems. When the system fails, the “code c0561” error notice may appear on the dashboard.
A defective EBCM can cause a full loss of the braking force. Furthermore, a faulty EBCM might cause the antilock brake system (ABS) to malfunction, resulting in a loss of vehicle control.
Another possibility is that the EBCM may be unable to regulate the braking system adequately, resulting in an unpleasant ride for passengers and excessive wear on the brakes.
In rare circumstances, replacing the EBCM may be required to remedy the problem.
How to Diagnose EBCM in a Chevy
- If there is a problem with the wiring, the brakes will most likely not work. Therefore, inspect the brake light wiring for shorts or openings.
- You may also notice anti-lock braking system (ABS) issues, such as a pulsing sensation in the brake pedal or steering wheel.
- Your brake pedal is spongy, or you’re having difficulty stopping your vehicle.
- A scan tool can also be used to look for flaws in the EBCM itself.
2. Module Errors
Multiple modules are responsible for transferring data signals to EBCM. Therefore, whenever some modules or sensors fail, they transmit incorrect information and data messages to your car system. This will cause the vehicle to malfunction. ECM and BCM are two examples.
3. A Faulty BCM
A defective BCM can cause a variety of difficulties with a vehicle, including issues with the electrical system, engine, or brake system. If you’re having trouble with your automobile, you know where the problem is. To diagnose the BCM, you need to examine the fuses and wiring system and replace anyone that is damaged.
4. Defective TCM
When a vehicle’s traction control module fails, the consequences might be severe. The module is responsible for controlling how much power is provided to the wheels.
5. Damaged ECM
The ECM regulates numerous parts of the engine, so if it fails, the automobile may not run well or at all. It is one of the most common causes of C0561. It is critical to have it repaired as soon as possible since the difficulties produced by a faulty ECM might worsen with time.
How to Fix C0561 Chevy Code
It is critical to repair code C0561 for the car to work correctly and this could result in an accident. Be careful to fully diagnose the code before digging in to repair it.
To resolve the C0561 error, begin by reviewing the “Possible Causes” stated above.
Examine the associated wire harness and connections visually. Examine the components for damage and search for broken, bent, pushed out, or rusted connecting pins and use the following steps.
- Repair defective EBCM
- Replacing a burned-out ABS sensor
- Change the traction control switch
- Increase the fluid level
- Check and repair any fluid leaks
- Tightly connect the EBCM wiring system
How Can I Prevent the C0561 Code From Reappearing in the Future?
Analyzing the problem and replacing the parts might be exhausting, right? Therefore, to avoid being in this situation, you must take certain precautions to prevent this code from being shown.
- Maintain tight and clean wiring connections
- Ensure you have sufficient fluid in your vehicle
- Have your vehicle inspected by a mechanic regularly
- Always follow your vehicle’s maintenance schedule.
You need to pay attention to any issues with the traction control system regarding the Chevrolet code C0561.
Reduced engine power, a check engine light, and an ABS light are the three major symptoms of a C0561 code.
As a result, correctly identifying the root cause of the problem, and repairing it may necessarily require the expert knowledge of a professional mechanic.
