What should I do if my Mazda CX-5 KF's traction control light stays on?

If the traction control light on your Mazda CX-5 KF (2017-2024) stays on, it indicates that the traction control system (TCS) has detected a fault or is actively engaged. Here’s a detailed step-by-step guide to diagnose and address the issue.

Parts/Components That May Need Replacement

• Wheel speed sensors (if faulty).
• ABS module (if diagnosed as faulty).
• Brake fluid (if low or contaminated).
• Fuses related to the ABS/TCS system (if blown).

Estimated Time for Repair

• Diagnostic Check: 30-60 minutes.
• Sensor Replacement: 1-2 hours (depending on which sensor is faulty).
• ABS Module Replacement: 2-3 hours (including programming if necessary).

Safety Warnings

• Always ensure the vehicle is securely lifted and supported with jack stands before working underneath it.
• Disconnect the battery before working on electrical components to prevent short circuits.
• Wear safety glasses and gloves to protect against debris and sharp edges.

Conclusion

If after following these steps the traction control light remains on, it is advisable to consult a professional technician or visit a Mazda dealership for further diagnosis and repair.
