Drive with caution
Drive with caution, particularly in wet, icy or loose conditions, since wheelspin will no longer be managed automatically while this fault is active.

Editorial review

If this light appears with brake, steering, airbag, overheating, oil pressure, fuel, smoke, or fire symptoms, treat it as safety-critical.

Short answer

This light has two distinct meanings. Flashing while driving means traction control is actively working — the system is limiting wheelspin right now. Staying on steadily means the system has faulted or been switched off.

Key takeaways

  • Flashing means working; steady means unavailable.
  • A traction light with an ABS light usually means one shared wheel speed sensor.

Can I still drive with this?

Drive with caution

Traction control light

This light has two distinct meanings. Flashing while driving means traction control is actively working — the system is limiting wheelspin right now. Staying on steadily means the system has faulted or been switched off.

Common triggers

  • Normal activation on a slippery surface, shown by a brief flash
  • A wheel speed sensor fault, which traction control shares with ABS
  • The system manually switched off, on vehicles that allow it
  • A steering angle or yaw sensor fault on vehicles where stability control is integrated

What to check

  1. Distinguish flashing from steady — flashing is the system working, steady is the system unavailable
  2. Check whether the system was switched off using the dashboard button
  3. Check whether the ABS light is on as well, which points at a shared wheel speed sensor
  4. Have it scanned if the light is steady with the system switched on

Frequently asked questions

It flashes when I accelerate on a wet road — is that a fault?

No, that is the system doing its job. Brief flashing under acceleration on a slippery surface is normal operation.

Why is the ABS light on too?

Both systems read the same wheel speed sensors. A single failed sensor commonly disables both functions at once, which is a useful diagnostic clue.
