What Does ABS + Traction Control Lights ON with Normal Braking Mean?
Reviewed by automotive technicians · Last updated August 22, 2026
Quick Answer
ABS + Traction Control Lights ON with Normal Braking = This combination usually indicates a failed wheel speed sensor or damaged ABS sensor wiring at one wheel. The ABS system has disabled itself, and because stability control relies on the same sensors, ESC is also disabled. Your regular brakes still work fine — the failure is in the anti-lock and stability systems only.

DRIVE WITH CAUTION — Repair Soon
This combination usually indicates a failed wheel speed sensor or damaged ABS sensor wiring at one wheel. The ABS system has disabled itself, and because stability control relies on the same sensors, ESC is also disabled. Your regular brakes still work fine — the failure is in the anti-lock and stability systems only.
What you see: ABS light (circle with ABS letters) and traction control light both illuminated orange, sometimes with a 'Check ESC' message
What to Do Right Now
You can drive normally — regular braking is unaffected. However, if you need to brake HARD in an emergency, the ABS will not pulse and your wheels may lock up. Avoid hard braking situations until repaired. The most common cause on Kia/Hyundai vehicles is a corroded or broken wheel speed sensor wire at the front wheels — inspect for visible damage before replacing sensors.
Emergency Action Guide
URGENCY: DRIVE WITH CAUTION
YELLOW — You can continue driving. Regular braking is unaffected — the ABS and traction control are disabled, but your normal brakes work fine. However, avoid situations where you need to brake hard on wet or slippery roads — without ABS, your wheels may lock up and the car will skid. Inspect the wheel speed sensor wires at both front wheels for visible damage.
Can you keep driving?
Yes, with caution — regular braking works fine. The ABS will not prevent wheel lockup during hard braking, and traction/stability control is disabled. Drive more carefully and leave extra following distance. Avoid hard braking, especially on wet roads. Get the sensor replaced within a week.
What happens if you ignore it?
MODERATE — your regular brakes work normally, but the anti-lock function is disabled. In an emergency stop on a wet or slippery road, your wheels may lock up and the car may skid instead of stopping in a straight line. Stability control is also disabled, so the car will not automatically correct for oversteer or understeer. Drive cautiously and fix the issue within a week.
Diagnosis & Cost
- Check if the red BRAKE light is also on (in addition to the ABS light). If only the ABS light is on, regular braking is fine — the anti-lock function is disabled but brake hydraulic pressure is normal. If the red BRAKE light is also on, check brake fluid level immediately.
- Visually inspect the wheel speed sensor wires at both front wheels. On Kia/Hyundai vehicles, the front sensor wires are exposed and prone to corrosion. Look for cracked insulation, frayed wires, or green corrosion at the connector.
- If the sensor wires look intact, remove each front wheel and check the sensor connector. Unplug and reconnect — sometimes a corroded connector just needs to be reseated. Apply dielectric grease to prevent future corrosion.
- If visual inspection does not find the problem, a mechanic can read the ABS module codes to identify which sensor has failed and what type of failure (open circuit, short circuit, or signal out of range).

Frequently Asked Questions
Can I drive my Kia Sorento with the ABS + Traction Control Lights ON with Normal Braking on?
Yes, but with caution. Drive directly to a mechanic and avoid hard acceleration or highway speeds. The vehicle is drivable but the affected system is not functioning correctly.
How much does it cost to fix the ABS + Traction Control Lights ON with Normal Braking on a Kia Sorento?
DIY cost estimate: $25-80 (wheel speed sensor — plug-and-play replacement, often just a single bolt and connector). Mechanic/dealer estimate: $200-400 diagnostic + sensor replacement; $150 if it's just a corroded connector cleaning. Costs vary by location, shop rate, and whether additional components are found to be damaged during diagnosis. Always get 2-3 quotes before authorizing repairs.
What causes the ABS + Traction Control Lights ON with Normal Braking to come on in a Kia Sorento?
This combination usually indicates a failed wheel speed sensor or damaged ABS sensor wiring at one wheel. The ABS system has disabled itself, and because stability control relies on the same sensors, . The most common causes vary by model year and driving conditions. See the troubleshooting section above for model-specific diagnostic guidance.
Why do both the ABS and traction control lights come on together?
The traction control and stability control systems rely on the ABS wheel speed sensors to function. When a wheel speed sensor fails, the ABS module disables itself, and because traction control depends on the same sensors, it is also disabled. Both lights come on because both systems are offline. Fixing the sensor restores both systems.
Is the corroded wheel speed sensor wire a known issue on Kia Sorento?
Yes — this is one of the most commonly reported issues on 2016+ Kia Sorento and Hyundai Santa Fe models. The front wheel speed sensor wires are exposed to road salt, water, and debris. Kia issued a TSB (Technical Service Bulletin) for this issue. Some dealerships will repair the wiring under warranty even if the basic warranty has expired — ask your dealer.
Can I clean a corroded sensor connector instead of replacing the sensor?
Yes — sometimes the connector pins are just corroded, not broken. Unplug the connector, spray both halves with electronic contact cleaner, scrub the pins gently with a small wire brush, apply dielectric grease, and reconnect. This free fix works about 30% of the time. If the light returns within a few days, the sensor itself needs replacement.
Will my Kia Sorento fail inspection with the ABS light on?
In most states that require safety inspections, an illuminated ABS warning light will cause a failed inspection. Stability control is federally mandated on all 2012+ vehicles, and a disabled ABS/traction control system is considered a safety deficiency. Fix the issue before your inspection deadline.
