The C0561-71 code is a diagnostic trouble code (DTC) that indicates an issue within the Electronic Stability Control System of a vehicle. This code typically appears on the dashboard and signals that the system has been disabled due to invalid data received from other modules. Understanding this code is crucial for vehicle owners, as it can affect overall driving safety and performance.

What is the C0561-71 Code?

The C0561-71 code signifies that the Electronic Brake Control Module (EBCM) has detected an invalid serial data message from another module, leading to the deactivation of the antilock brake system (ABS), traction control, and electronic stability control systems. This situation often arises from issues such as:

  • Faulty wheel speed sensors
  • Improper brake pressure adjustments
  • Malfunctioning control modules

When this code appears, it is essential to address it promptly to ensure vehicle safety.
