Understanding this warning light helps you know when your vehicle needs attention. It also improves your safety while driving in tough conditions.
Common Symbols Explained
The squiggly lines light usually looks like a car with curvy lines behind it. This icon means the traction or stability control system is active or has a problem. It may blink during slippery road conditions or stay on if there is a fault.
- Car with squiggly lines means traction control is working.
- A blinking light shows the system is active on slippery roads.
- A steady light means the system has a problem and needs checking.
When The Light Appears
This light comes on mainly in two cases. It flashes when the car loses grip, such as on wet or icy roads. It stays on if the traction control system has a malfunction.
| Condition | Light Behavior | Action Needed |
| Slippery Road | Blinks | Drive carefully, system is active |
| System Fault | Stays On | Get the system checked by a mechanic |
Impact On Driving Safety
The traction control system helps prevent skidding and loss of control. It improves safety by adjusting the brakes and engine power. The squiggly lines light warns you if this system is working or has issues.
Safety Tips:
- Slow down if the light blinks on slippery roads.
- Do not ignore the light if it stays on after starting your car.

Possible Causes
The car with squiggly lines light shows when the vehicle senses traction problems. This warning means the car’s safety systems are working. It helps keep you safe on slippery or rough roads.
Several issues can trigger this light. Understanding these causes helps you know what to check or fix.
Traction Control Issues
Traction control stops wheels from slipping during acceleration. If this system has a problem, the light may turn on. Faulty traction control can cause poor grip on the road.
Common traction control issues include worn brake parts, bad sensors, or electrical faults. These can stop the system from working correctly.
Stability Control Problems
Stability control helps keep your car steady during turns or sudden moves. If it detects trouble, the squiggly lines light appears. Problems in this system reduce your car’s balance and safety.
Failures in stability control often come from bad sensors or damaged wiring. These problems stop the system from controlling the car’s movement properly.
Sensor Malfunctions
Sensors send data to traction and stability control systems. If sensors fail, the car may show the warning light. Dirty or broken sensors give wrong information to the system.
- Wheel speed sensors can get dirty or damaged
- Steering angle sensors may lose calibration
- Yaw rate sensors might fail due to electrical issues
Fixing or cleaning sensors often clears the light and restores normal function.
Weather And Road Conditions
Slippery roads from rain, snow, or ice can trigger the squiggly lines light. The car senses wheel slip and alerts the driver. This warning helps you drive carefully on unsafe surfaces.
Rough or uneven road surfaces may also cause the light to flash. The system tries to keep control despite the challenging conditions.
Diagnosing The Problem
The car with squiggly lines light on means there is a traction or stability issue. This warning shows when the car’s system detects slipping or control loss.
Finding out why this light is on helps keep the car safe. You can check some things yourself before going to a mechanic.
Using Onboard Diagnostics
Most cars have a computer system that stores error codes. You can use an OBD-II scanner to read these codes. This shows what might be wrong.
OBD-II scanners are easy to use and connect under the dashboard. The codes help you or a mechanic find the problem faster.
- Plug the scanner into the OBD-II port
- Turn the ignition to the “on” position
- Read the error codes on the scanner screen
- Look up the code meanings in the manual or online
Visual Inspection Tips
Check your tires first. Worn or low-pressure tires often cause traction control issues. Also look for damaged wheel sensors.
Look under the car for leaks or broken parts. Dirt or ice on sensors can cause false alerts. Cleaning these can fix the problem.
- Check tire tread and pressure
- Inspect wheel speed sensors for dirt or damage
- Look for fluid leaks near brakes or suspension
- Clean any dirty or icy sensors carefully
When To Visit A Mechanic
If the light stays on after checks, see a mechanic. Persistent warnings may need special tools and knowledge.
A mechanic can test sensors, wiring, and system parts. They fix problems that affect your car’s safety and performance.
- The warning light flashes or stays on constantly
- You notice strange noises or poor handling
- Basic checks do not fix the warning light
- The car’s braking or stability feels off
Fixing The Issue
The car with squiggly lines light shows a problem with the traction or stability system. Fixing this issue helps keep the car safe on the road.
There are several ways to fix the problem. You can reset the system, replace sensors, maintain tires and brakes, or update the software.
Resetting The System
Sometimes the light stays on due to a small glitch. Resetting the system can clear the error and turn off the light.
You can reset by turning the car off and on or disconnecting the battery for a few minutes. This may fix the issue if it is not serious.
Replacing Faulty Sensors
The squiggly lines light can turn on if a sensor is broken or dirty. Sensors check wheel speed and road conditions.
Check sensors for damage or dirt. Replace any faulty sensors to fix the light and improve car safety.
- Inspect wheel speed sensors
- Clean sensor surfaces carefully
- Replace sensors if broken
Tire And Brake Maintenance
Worn tires or brakes can cause the traction system to alert you. Good tire grip and brake function keep the car stable.
Check tire pressure and tread depth regularly. Inspect brakes for wear and replace brake pads if needed.
- Check tire pressure monthly
- Measure tire tread depth
- Replace worn brake pads
- Keep brakes clean and functional
Software Updates
The car’s computer controls the traction system. Sometimes software bugs cause the warning light to come on.
Updating the car’s software can fix errors and improve system performance. Visit a service center for software updates.
Preventive Measures
The car with squiggly lines light warns you about vehicle stability issues. Taking preventive steps can keep you safe.
Knowing how to respond and maintain your car helps avoid accidents and costly repairs.
Regular Vehicle Maintenance
Check your car’s brakes, tires, and suspension often. These parts affect your car’s stability on the road.
Replace worn tires and brake pads quickly. Keep your vehicle clean and free from debris that can affect sensors.
