C0561 Chevy – All the Possible Causes, Symptoms, and Fix Guide

This article will provide a detailed guide on what the C0561 code means and how to fix it. Additionally, we’ll discuss some of the possible causes and symptoms of this code, as well as how to prevent it from happening in the first place.

What Does C0561 Mean on Your Chevy?

All C codes represent diagnostic issues with the chassis. C0561 Chevy diagnostic GM code is associated with problems related to the drivetrain or traction control system.

The EBCM of your vehicle receives information from multiple modules and sensors. It gets the data signals from the following modules:

  • Body control module
  • Engine control module
  • Transmission control module
  • Information panel cluster

The information from these modules assists in regulating the functions associated with ABS. Further, TCS gets all the information from ABS. If a wheel is spinning faster relative to the other one, it stores a DTC. Moreover, a DTC is also stored when any of the wheels lock up.

If you’re seeing this code, it’s important to know about all the symptoms and causes associated with it. Further, you should fix it as soon as possible to avoid further damage.

Understanding the C0561 code on a Chevy

Before moving on to the detailed meaning of the C0561 code, it is important to understand the following terms.

EBCM: An electronic brake control module (EBCM) is a device used to control the braking system of a vehicle. It receives input from sensors throughout the vehicle and determines how much pressure to apply to the brakes.

ECM: The ECM regulates fuel injection, ignition timing, and other functions to optimize the engine’s performance.

BCM: The BCM receives input from sensors throughout the vehicle and sends commands to actuators that control the devices. It also monitors various systems, such as the engine, brakes, and airbags.

IPC: An instrument panel cluster displays information about the status of the vehicle’s systems to the driver. The cluster typically contains a speedometer, tachometer, fuel gauge, and various warning lights.

TCM: TCM receives input from sensors about the vehicle’s speed, engine rpm, and gear position, and it uses this information to calculate how much torque to apply to the transmission. The TCM also adjusts the transmission’s shift points to match the driving conditions.

ABS: An anti-lock brake system (ABS) is a system on a vehicle that helps to prevent the wheels from locking up during braking. This helps the driver to maintain control of the vehicle.

VSES: This system monitors the position and movement of the car and intervenes when it detects that the vehicle is starting to skid or lose control.

TCS: Traction control systems are a type of electronic stability control system that helps drivers maintain control of their vehicles by reducing wheel slip.

Is C0561 Something to Worry About?

A C0561 diagnostic code is not something to really worry about. It can be fixed with minimal effort. However, it is important to diagnose the root of this code and fix it as soon as possible. This will avoid further damage to the vehicle.

C0561 Code- All the Symptoms You Will Experience

You will experience multiple symptoms when the C0561 code comes on, therefore, it is important to have an adequate understanding of what symptoms might cause.

Reduced Engine Power

One of the most common symptoms of C0561 traction issues is reduced engine power. Reduced engine power means that the car’s acceleration and top speed are both lower than usual. This can make it difficult to get around town or travel on the highway.

ABS Light On

If you see the ABS light illuminated on your dashboard, it’s important to check for traction control problems. It is one of the major symptoms which can be caused by a number of different problems.

Engine Light On

One of the potential causes of this light coming on is a traction issue. If you’re experiencing a traction issue, you may find that your car doesn’t respond well to acceleration or braking and may even slip or skid when trying to make a turn. If you’re seeing the engine light come on, you might be dealing with a traction issue.

Causes of the C0561- Explained

C0561 is a code that indicates a problem with the traction control system in a Chevy vehicle. There are many possible causes, and each one needs to be investigated before the problem can be fixed. Here are two of the most common causes of C0561.

Faulty EBCM

The electronic brake control module (EBCM) is responsible for controlling the braking system and stability control systems on most modern vehicles. When the EBCM fails, it can cause the “code c0561” error message to be displayed on the dashboard.

The effects of faulty EBCM can range from a warning light on the dashboard to a complete loss of braking power. Furthermore, a defective EBCM can also cause the antilock brake system (ABS) to malfunction, leading to a loss of control over the vehicle.

Another potential issue is that the EBCM may not be able to properly modulate the braking system, resulting in an uncomfortable ride for passengers and excessive wear on the brakes. In some cases, it may be necessary to replace the EBCM in order to resolve the issue.


There are a few tell-tale signs that can help you determine whether or not the EBCM is malfunctioning.

  • One is to check the brake light wiring for shorts or opens. If there is a problem with the wiring, it will likely affect the operation of the brakes.
  • You might also experience problems with the anti-lock braking system (ABS), such as a pulsing sensation in the brake pedal or steering wheel.
  • Your brake pedal feels spongy, or you’re having problems stopping your car.
  • You can also check for faults in the EBCM itself by using a scan tool.

Replacing EBCM is quite costly. Thus, you should make it sure that it is what is causing problems before proceeding to purchase it.

Faulty Modules

There are multiple modules that can be faulty. These defective modules and sensors will convey inaccurate information and data messages. This will lead to the malfunctioning of the vehicle. There are multiple modules that transfer the data signals to EBCM. A few of them are ECM and BCM.

Defective BCM

A faulty BCM can result in a number of issues with a car, such as problems with the electrical system, the engine, or the braking system. If you are experiencing any problems with your car, you know where the problem lies.


There are a few things you can do to try to diagnose the issue.

  • Check the fuses and replace any that are blown.
  • Check the wiring harness for damage or corrosion.

If everything looks good, then it’s likely that the BCM is faulty and needs to be replaced.

Defective ECM

The ECM controls many aspects of the engine, so when it is not working properly, the car may not run well or at all. It is one of the prime causes of code C0561. It is important to get it fixed as soon as possible, as the problems caused by a defective ECM can get worse over time.


In order to diagnose an ECM problem, you should test its functionality. You can do this by disconnecting the battery and reconnecting it. You can also detect a faulty ECM if:

  • The engine will not start
  • The engine dies while driving
  • The car hesitates when accelerating
  • The check engine light comes on

Defective ICP

Defective ICP will not provide information to EBCM. This can lead to multiple issues. One common one is that the odometer will stop working, so drivers won’t have any idea how far they’ve driven.


To diagnose a problem with the information control module, you will need to use a scan tool.

Defective TCM

When a car’s traction control module malfunctions, the results can be disastrous. The module is responsible for controlling the amount of power sent to the wheels, and when it fails, the car can skid or lose control.


One way to diagnose this is to check the fuses and relays. If they are all good, then it is likely that the module is defective. In order to replace it, you will need to remove the under-hood panel and access the module.
