When dashboard lights come on, it’s always a sign that something needs attention. If both your ABS light and traction control light appear at the same time, it usually means the two systems are linked by a common issue. Both are designed to help keep your vehicle stable and safe in different driving conditions, so ignoring these warnings can increase your risk on the road.
Here’s what those lights mean, why they often turn on together, and what steps you should take next.
What the ABS System Does
Your Anti-lock Braking System (ABS) prevents your wheels from locking up during sudden stops. It utilizes wheel speed sensors and a control module to rapidly adjust brake pressure, enabling you to maintain steering control when braking hard or driving on slippery surfaces. Without it, your wheels may skid during emergency stops, making it harder to avoid obstacles.
What the Traction Control System Does
The traction control system works hand in hand with ABS. It monitors wheel speed and reduces power or applies braking to individual wheels if it detects one starting to slip. This keeps your tires gripping the road better during acceleration, especially in wet, icy, or uneven conditions. When the light turns on, it means the system is no longer actively protecting against wheel slip.
Why Both Lights May Come On Together
Since ABS and traction control share sensors and often the same control module, a problem in one system can trigger both warning lights. Some of the most common causes include:
- A faulty wheel speed sensor
- Damaged or dirty tone rings on the wheel hubs
- Wiring or connection issues
- A failed ABS control module
- Low brake fluid or hydraulic pressure problems
When the car’s computer can’t rely on accurate sensor readings, it may shut down both systems to avoid sending incorrect commands.
How It Affects Your Driving
If these lights are on, your vehicle will still drive, but it won’t have the added protection of ABS or traction control. That means in an emergency stop, your wheels could lock up. On slippery roads, your tires may spin more easily without traction control correcting them. You’ll need to drive more cautiously and allow extra distance for stopping.
What You Should Check First
Start with the basics. Check your brake fluid level, since a low level can sometimes trigger the ABS light. Also, make sure your tires are properly inflated and in good condition, as uneven tire sizes or pressures can confuse the system. Beyond that, the issue is likely sensor or wiring-related, which requires diagnostic equipment to confirm.
How a Technician Diagnoses the Problem
To find the cause, our technicians connect diagnostic tools to your vehicle’s onboard computer. The system stores trouble codes that indicate which sensor or component isn’t functioning as expected. From there, we can test the wheel speed sensors, inspect wiring, or evaluate the ABS module. Sometimes, a simple sensor cleaning is enough, while in other cases, a part replacement is necessary.
