If your scan tool displays C0561, it does not necessarily indicate a failed component. Instead, this diagnostic trouble code tells you that one of your vehicle’s chassis control modules has intentionally disabled a safety system after receiving fault information from another module. In most cases, the Electronic Brake Control Module (EBCM) stores C0561 because another controller—such as the Powertrain Control Module (PCM), Transmission Control Module (TCM), or Transfer Case Control Module (TCCM)—reported a problem that could affect safe vehicle operation.
Unlike most chassis codes, C0561 is an informational or companion code. It does not identify the original failure. Instead, it indicates that systems like ABS, Traction Control, Electronic Stability Control (ESC/StabiliTrak), or All-Wheel Drive have been temporarily disabled because another fault could compromise their operation.
On many GM vehicles, C0561 commonly appears alongside engine, transmission, steering angle sensor, wheel speed sensor, or transfer case codes. Repairing the primary diagnostic trouble code usually causes C0561 to clear automatically.

What Does C0561 Mean?
The C0561 code indicates that a chassis control module—most commonly the Electronic Brake Control Module (EBCM)—has disabled one or more vehicle safety systems after receiving fault information from another module.
Modern vehicles constantly exchange information across the Controller Area Network (CAN bus).
The EBCM communicates with modules including:
- Powertrain Control Module (PCM)
- Transmission Control Module (TCM)
- Transfer Case Control Module (TCCM)
- Body Control Module (BCM)
- Steering Angle Sensor Module
- Airbag Control Module
- Instrument Cluster
If one of these controllers reports a fault that could affect vehicle stability, braking, or traction, the EBCM disables certain features and stores C0561.
Depending on the vehicle, affected systems may include:
- Anti-lock Braking System (ABS)
- Traction Control System (TCS)
- Electronic Stability Control (ESC)
- StabiliTrak
- Roll Stability Control
- Hill Start Assist
- Trailer Sway Control
- All-Wheel Drive coordination
The important point is that C0561 rarely identifies the root cause. It simply confirms that another system fault has caused the EBCM to disable one or more safety features.
Symptoms of C0561
Common symptoms include:
- ABS warning light
- Traction Control warning
- StabiliTrak warning
- Electronic Stability Control warning
- Service Stabilitrak message
- Stored C0561 diagnostic code
Additional symptoms may include:
- Traction control disabled
- ABS disabled
- Stability control unavailable
- Cruise control disabled
- Four-wheel drive disabled on some vehicles
- Multiple dashboard warning lights
- Reduced driver assistance functions
Vehicle drivability often depends entirely on the primary fault that triggered C0561.
Common Causes
Engine Performance Problems
Engine-related faults frequently trigger C0561.
Examples include:
- Misfires
- Electronic throttle control faults
- Reduced engine power mode
- Torque management errors
- Fuel system problems
The EBCM disables traction and stability control because it cannot accurately predict engine torque.
Transmission Problems
The TCM may report:
- Shift errors
- Limp mode
- Internal transmission faults
- Torque converter problems
These conditions may cause the EBCM to disable stability control.
Transfer Case Faults
On four-wheel-drive vehicles, transfer case problems may trigger C0561.
Examples include:
- Encoder motor faults
- Shift failures
- Front axle actuator faults
- Transfer case communication errors
Steering Angle Sensor Errors
The steering angle sensor provides critical data for:
- Stability control
- Yaw correction
- Traction control
If calibration is lost or the sensor fails, the EBCM disables stability systems.
Wheel Speed Sensor Failures
ABS wheel speed sensors are among the most common causes of C0561.
A failed sensor prevents the EBCM from calculating:
- Wheel slip
- Vehicle direction
- Brake intervention
- Traction control operation
Yaw Rate Sensor Problems
The yaw rate sensor measures vehicle rotation.
Incorrect readings prevent ESC from determining whether the vehicle is skidding.
Brake Pressure Sensor Faults
Brake pressure information helps the EBCM coordinate braking and stability functions.
Sensor failures may disable several electronic safety systems.
CAN Bus Communication Errors
Communication failures between modules can trigger C0561.
Possible causes include:
- Damaged wiring
- Corroded connectors
- Network shorts
- Failed modules
Low Battery Voltage
Weak batteries may cause:
- Module resets
- Communication failures
- Temporary stability control disablement
Battery condition should always be verified first.
Faulty Control Module
Although less common, an internally failed:
- PCM
- TCM
- EBCM
- TCCM
may report invalid information that triggers C0561.
How Serious Is C0561?
Moderately serious.
The vehicle usually remains drivable.
However, important safety systems may become unavailable, including:
- ABS
- Traction Control
- Stability Control
- StabiliTrak
- Trailer Sway Control
Emergency handling performance may be reduced during slippery driving conditions.
Can You Drive With C0561?
Usually, yes.
Most vehicles continue operating normally.
However:
- ABS may not function.
- Stability control may be disabled.
- Traction control may be unavailable.
- Wheel spin may increase on wet or icy roads.
- Emergency handling assistance may be reduced.
Drive cautiously until the underlying fault has been repaired.
How to Diagnose C0561
1. Scan Every Control Module
Do not stop after reading C0561.
Use a professional scan tool capable of reading:
- PCM
- TCM
- EBCM
- BCM
- TCCM
- Steering modules
The primary fault usually exists elsewhere.
2. Repair Higher-Priority Codes First
If engine, transmission, ABS, or transfer case codes are present, diagnose those first.
In many cases, C0561 disappears once the original problem is repaired.
3. Inspect Battery Voltage
Measure:
- Battery voltage (approximately 12.6 volts engine off)
- Charging voltage (approximately 13.5–14.8 volts engine running)
Low voltage commonly causes communication issues.
4. Inspect Wheel Speed Sensors
Verify:
- Sensor operation
- Wiring integrity
- Connector condition
- Tone ring condition
Wheel speed sensor failures are extremely common.
5. Verify Steering Angle Sensor Calibration
Many vehicles require steering angle calibration after:
- Wheel alignment
- Suspension repairs
- Steering rack replacement
- Battery replacement (on some models)
Use a professional scan tool to verify calibration.
6. Check CAN Bus Communication
Inspect for:
- Communication errors
- Module offline conditions
- Corroded connectors
- Damaged wiring
Repair network faults before replacing modules.
7. Clear Codes and Road Test
After repairing the primary fault:
- Clear all DTCs.
- Perform a road test.
- Verify C0561 does not return.
If it does, continue diagnosing the originating module.

Once the underlying fault is repaired and the codes are cleared, C0561 typically does not return.
Final Thoughts
The C0561 code indicates that a chassis control module has disabled one or more safety systems after receiving fault information from another module. Rather than identifying a failed sensor or component, it serves as a notification that systems such as ABS, traction control, or electronic stability control have been intentionally turned off because another issue could affect their safe operation.
The key to repairing C0561 is to identify and fix the primary diagnostic trouble code that triggered it. By performing a complete system scan, verifying battery voltage, checking wheel speed sensors and communication networks, and addressing any engine, transmission, or transfer case faults, you can usually restore full chassis system functionality without replacing unnecessary parts.
