The C0561-71 code is a diagnostic trouble code (DTC) that indicates a problem within the Electronic Stability Control (ESC) system of a vehicle, particularly in General Motors (GM) models. This code can lead to various issues, including the deactivation of the Anti-lock Braking System (ABS) and traction control systems. Understanding this code is crucial for vehicle owners, especially those experiencing symptoms like warning lights or unusual braking behavior.
The C0561-71 code specifically signifies that the Electronic Brake Control Module (EBCM) has received invalid serial data from other vehicle modules. This can result from faulty sensors, wiring issues, or even problems with the EBCM itself. Addressing this code promptly is essential to ensure safe vehicle operation and to avoid further complications.

| C0561-71 | System disabled due to invalid serial data received |
Understanding the C0561-71 Code
The C0561-71 code is primarily associated with GM vehicles and indicates a malfunction in the traction control system. When this code appears, it means that the EBCM has detected an issue with the data it receives from other modules, which may include the Body Control Module (BCM), Engine Control Module (ECM), and Transmission Control Module (TCM). The EBCM relies on accurate data to function correctly; thus, any discrepancies can lead to system deactivation.
Important info: The C0561-71 code can manifest due to various reasons, including:
- Faulty wheel speed sensors
- Damaged wiring or connectors
- Malfunctioning EBCM
- Issues with brake pressure sensors
When diagnosing this code, it’s vital to check for any related codes that may provide additional context regarding the underlying issue.
Symptoms of C0561-71
When the C0561-71 code is triggered, drivers may experience several symptoms that indicate a problem with their vehicle’s stability control systems. Common symptoms include:
- Illuminated warning lights: The ABS light and traction control light may remain on.
- Unusual brake behavior: Drivers might notice their brakes behaving erratically or feeling less responsive.
- Loss of traction control: The vehicle may not respond as expected during slippery conditions due to disabled traction control.
- Service Stabilitrak message: This message may appear on the dashboard, indicating issues with the stability control system.
Recognizing these symptoms early can help prevent further damage and ensure timely repairs.
Diagnosing C0561-71
To effectively diagnose the C0561-71 code, follow these steps:
1. Use a diagnostic scanner: Connect an OBD-II scanner to retrieve the trouble codes. Look for related codes that may help pinpoint the issue.
2. Inspect wiring and connectors: Check all wiring and connectors associated with the EBCM and wheel speed sensors for signs of damage or corrosion.
3. Test wheel speed sensors: Ensure that all wheel speed sensors are functioning correctly by checking their resistance and voltage output.
4. Check brake pressure sensors: Inspect brake pressure sensors for proper operation as they play a crucial role in stability control.
5. Examine EBCM functionality: If no other issues are found, consider testing or replacing the EBCM itself, as it may be receiving or sending incorrect data.
By following these diagnostic steps, vehicle owners can identify the root cause of the C0561-71 code and take appropriate action.
Repairing C0561-71
Repairing the C0561-71 code typically involves addressing any identified faults in the vehicle’s stability control system. Here are some common repair solutions:
- Replace faulty wheel speed sensors: If any wheel speed sensors are found to be malfunctioning, replacing them can resolve the issue.
- Repair damaged wiring: Fix any damaged wires or connectors that could be interrupting communication between modules.
- Calibrate or replace EBCM: If diagnostics indicate a problem with the EBCM itself, recalibration or replacement may be necessary.
- Clear codes and test drive: After repairs, clear all trouble codes using a scanner and take the vehicle for a test drive to ensure that no new codes appear and that systems function correctly.
Addressing these repairs promptly will help restore normal function to your vehicle’s stability control systems.
Preventive Measures
To avoid encountering the C0561-71 code in the future, consider implementing these preventive measures:
- Regular maintenance checks: Schedule routine inspections of your vehicle’s braking system and electronic components to catch potential issues early.
- Keep wiring clean and dry: Ensure that wiring connections remain free from moisture and corrosion by regularly inspecting them.
- Monitor warning lights: Pay attention to dashboard warning lights and address any alerts immediately rather than waiting for symptoms to worsen.
By taking these preventive steps, you can maintain your vehicle’s performance and reduce the likelihood of encountering diagnostic trouble codes like C0561-71.
