ABS and traction control lights illuminate when there’s a malfunction in your vehicle’s braking or stability systems. These warning indicators shouldn’t be ignored as they affect your vehicle’s safety features, potentially compromising control during emergency situations or on slippery surfaces.
Why Are My ABS and Traction Control Lights On?
ABS (Anti-lock Braking System) prevents wheel lock-up during hard braking, maintaining steering control. Traction control prevents wheel spin during acceleration on slippery surfaces.
These interconnected systems share components like wheel speed sensors and control modules. When one system detects a fault, both may disable as a precaution.
The lights illuminate briefly during startup for system checks but staying on indicates a detected problem.
When both your ABS light and traction control light come on simultaneously, your vehicle is alerting you to a potential safety issue. These systems form the foundation of your car’s active safety network.
The relationship between these systems is crucial to understand. Your ABS system monitors wheel rotation during braking, while the traction control system monitors wheel rotation during acceleration. Both rely on the same sensors and often the same control module.
Many drivers don’t realize that when these lights illuminate, the systems have typically disabled themselves as a protective measure.
Is It Safe to Drive When ABS and Traction Control Lights Are Illuminated?
Standard brakes still work when ABS/traction lights are on, but you lose anti-lock and stability features. Drive cautiously in good conditions, but avoid adverse weather. If the regular brake warning light is also on, stop driving immediately.
| Condition | Safety Level | Recommendation |
|---|---|---|
| Both lights on, no other symptoms | Moderately safe | Drive cautiously, avoid harsh braking |
| Both lights on with brake warning light | Unsafe | Do not drive – potential brake failure |
| Lights on with noticeable braking issues | Unsafe | Seek immediate assistance |
| Lights on in good weather, flat roads | Relatively safe | Schedule repair soon |
| Lights on during adverse conditions | Unsafe | Postpone travel if possible |
The question “is it safe to drive with ABS and traction light on” depends on several factors. When only these warning lights are illuminated, your standard brakes still function, but you lose the anti-lock feature and traction assistance.
This means your wheels could lock up during hard braking or spin during acceleration, particularly in adverse conditions. Your vehicle becomes more vulnerable on wet, icy, or uneven surfaces.
If you notice the brake warning light illuminated alongside the ABS and traction control lights, this indicates a more serious problem with the fundamental braking system. In this case, stop driving immediately and seek professional help.
Drivers should be especially cautious if they notice the ABS and traction control light comes on and off intermittently, as this often indicates an electrical issue that could worsen unpredictably.
What Causes Both ABS and Traction Control Lights to Come On Simultaneously?
Common causes include electrical problems, wheel speed sensor failures, ABS module malfunctions, brake fluid issues, and damaged wiring. These systems share components, so a single failure often affects both simultaneously.
Common Electrical System Problems
Voltage irregularities from a failing battery or alternator can cause electronic systems like ABS and traction control to malfunction. These systems require stable voltage to operate correctly.
Recent battery replacement or disconnection might trigger these lights until the systems recalibrate. Sometimes a simple reset will solve the problem.
When diagnosing why your ABS and traction control light on after battery change, remember that these sophisticated systems often need to relearn certain parameters after power interruption.
Corroded battery terminals or ground connections can cause intermittent electrical issues that affect multiple systems, sometimes making the ABS light comes on intermittently.
Wheel Speed Sensor Failures
Wheel speed sensors are critical components that:
- Monitor the rotation speed of each wheel
- Send data to the ABS and traction control modules
- Help detect when a wheel is locking up or spinning
- Allow the systems to apply selective braking
Common causes of sensor failures include:
- Physical damage from road debris
- Wire harness damage
- Connector corrosion
- Magnetic buildup on the sensor
- Internal sensor failure
A bad wheel speed sensor is one of the most common reasons for ABS and traction control light on causes. These sensors are exposed to harsh conditions and can deteriorate over time.
When a wheel speed sensor fails, the ABS and TC light on situation typically develops because both systems rely on accurate wheel speed data to function properly.
ABS Module Malfunctions
The ABS module is the electronic brain that processes input from sensors and controls the ABS and traction control systems. When it fails, both systems typically shut down.
Symptoms of a failing ABS module include erratic brake performance, unresponsive brakes, ticking noises, and in severe cases, the brakes may suddenly engage without warning.
Water damage, electronic component failure, or software glitches can all cause the module to malfunction, resulting in ABS and traction control light on fix requirements that often involve module replacement or reprogramming.
The ABS traction control warning light combination often points to module issues when other components check out normally during diagnostics.
Low Brake Fluid or Pressure Issues
Low brake fluid can trigger the ABS light because the system relies on proper hydraulic pressure. Many vehicles have sensors in the fluid reservoir that detect when levels drop below safe thresholds.
When you see the ABS and traction control light on due to low brake fluid, it’s crucial to check for leaks in the system rather than simply topping off the fluid.
Air in the brake lines, leaking brake fluid, or a failing brake master cylinder can all cause pressure irregularities that trigger warning lights, sometimes making the ABS and brake warning lights stay on until the underlying issue is addressed.
Brake fluid that has absorbed too much moisture over time can also cause system malfunctions, particularly in cold weather.
Damaged Wiring or Connectors
Wiring issues are common in older vehicles or those exposed to harsh conditions. Damaged wires can send incorrect signals or no signals at all to the control modules.
Connectors exposed to road salt, water, or vibration can develop corrosion or become loose, creating intermittent problems that are difficult to diagnose, often resulting in intermittent ABS traction control light activation.
Rodent damage to wiring harnesses is surprisingly common and can affect multiple vehicle systems simultaneously. This type of damage often requires extensive ABS and traction control troubleshooting.
After hitting a pothole or road debris, you might notice traction control and ABS light after hitting pothole due to wiring damage or sensor displacement.
How Do I Diagnose ABS and Traction Control Light Issues?
Check for additional warning lights, note any driving performance changes, use an OBD-II scanner to read error codes, and visually inspect wheel sensors, wiring, and brake fluid level.
Step 1: Check for Other Warning Lights
The check engine light alongside ABS and traction control lights may indicate a complex issue affecting multiple systems, often pointing to computer network problems. The brake warning light plus ABS/traction control suggests serious brake system issues like low fluid or leaks requiring immediate attention. The stability control light (car icon with squiggly lines) frequently illuminates with ABS/traction control since these systems work together.
When the ABS light traction light check engine light all illuminate together, this typically indicates a more serious electrical or computer-related issue affecting multiple systems.
Understanding what the ABS light on dashboard meaning is in context with other warning lights can help narrow down potential causes. For example, the ABS and handbrake light on combination often points to a brake fluid level issue.
The ABS and anti skid warning light meaning relates to stability control, which works alongside ABS and traction control to prevent skidding during cornering or emergency maneuvers.
Step 2: Observe Driving Performance Changes
Watch for these symptoms to help identify the problem:
- Pulsating brake pedal when not braking hard
- Unusual noises when applying brakes
- Increased stopping distance
- Vehicle pulling to one side during braking
- Wheel lock-up during normal braking
- Loss of traction during acceleration
- Vibration through the steering wheel
When experiencing ABS traction light car shaking, the issue might be related to a damaged tone ring or wheel bearing, which affects sensor readings.
Pay attention to when the lights activate. For instance, ABS and traction control light on when braking specifically might indicate a problem with the brake pressure sensor or switch.
If you notice ABS and traction light on cold weather patterns, this could indicate moisture in connectors or temperature-sensitive component failures.
Step 3: Use an OBD-II Scanner
| Common ABS/TC Code | Likely Meaning | Typical Fix |
|---|---|---|
| C0035-C0038 | Wheel speed sensor circuit failure | Replace sensor |
| C0040-C0045 | Brake pressure sensor issue | Repair/replace sensor |
| C0110 | Pump motor circuit malfunction | Repair wiring or replace pump |
| C0121 | Valve relay circuit failure | Replace ABS module |
| C0196 | Wheel speed sensor tone ring | Replace tone ring |
| U0123 | Communication error with other modules | Diagnose network issue |
Using an OBD-II scanner for ABS and traction light on diagnostic scan is the most precise way to identify the specific issue. This tool can reveal exactly which component is malfunctioning.
Most auto parts stores offer free code reading services if you don’t own a scanner. More advanced scanners can access ABS-specific codes and perform system tests to identify what triggers ABS and traction control lights.
Understanding these codes helps determine whether you’re dealing with a simple sensor issue or a more complex ABS and traction control system fault.
Step 4: Inspect Visual Components
Check wheel speed sensors for damage, debris, or loose connections. These are typically located at each wheel near the brake assembly.
Inspect brake fluid level and condition in the master cylinder reservoir. Low or discolored fluid can indicate problems.
Look for damaged wiring, particularly around the wheels where road debris can cause harm. Follow harnesses from wheel sensors to connection points.
Visual inspection can often reveal ABS and traction light on bad wheel speed sensor situations where the sensor or its wiring has been physically damaged.
How to Reset ABS and Traction Control Lights
Reset lights by disconnecting the battery for 15-20 minutes or using an OBD-II scanner to clear codes. If lights return after reset, further diagnosis is needed as the underlying problem remains.
Battery Disconnection Method
Step 1: Ensure the vehicle is completely off and the key is removed.
Step 2: Open the hood and locate the battery.
Step 3: Disconnect the negative (black) battery terminal.
Step 4: Press and hold the brake pedal for 15-20 seconds to drain residual power.
Step 5: Reconnect the negative battery terminal.
Step 6: Start the vehicle and check if the warning lights reset.
This method forces the vehicle’s computers to reset and can clear temporary glitches, providing a simple way to reset ABS and traction control light.
For drivers wondering how to turn off ABS and traction control light after making repairs, this battery disconnection method often works for temporary issues.
This approach is particularly useful when dealing with an ABS and traction light reset situation after minor repairs or battery replacement.
Using an OBD-II Scanner to Clear Codes
Step 1: Connect the OBD-II scanner to the diagnostic port (usually under the dashboard).
Step 2: Turn the ignition to the "on" position without starting the engine.
Step 3: Navigate to the "ABS" or "Chassis" section of the scanner menu.
Step 4: Select "Read Codes" to identify the specific issue.
Step 5: After repairs, select "Clear Codes" to reset the warning lights.
Step 6: Cycle the ignition and test drive to ensure lights remain off.
Using a scanner is the most reliable method for how to reset traction control light issues after repairs have been completed.
This method allows you to verify that the repair was successful by checking if codes return after clearing them.
For those wondering how to fix ABS and traction control light on problems, the scanner approach provides diagnostic information before attempting any reset.
When Resets Don’t Work
If lights return after reset, this indicates an ongoing problem that needs repair. Temporary resets won’t fix mechanical or electrical failures.
When the ABS and traction control light won’t turn off after reset attempts, this strongly suggests a component failure requiring replacement.
Some vehicles require specific relearning procedures after repairs, especially for steering angle sensors or after battery replacement.
If you find that ABS and traction control light on and off intermittently continues after reset attempts, you likely have an electrical connection issue.
DIY Fixes for ABS and Traction Control Light Issues
Common DIY repairs include cleaning/replacing wheel speed sensors, fixing electrical connections, checking brake fluid, and inspecting wiring. Clear error codes after repairs to reset the system.
Cleaning or Replacing Wheel Speed Sensors
Step 1: Locate the wheel speed sensor (usually mounted at the wheel hub or axle).
Step 2: Disconnect the electrical connector carefully.
Step 3: Remove the mounting bolt and extract the sensor.
Step 4: Clean the sensor tip and mounting hole with electronic cleaner.
Step 5: Inspect for damage - replace if cracked or worn.
Step 6: Reinstall the sensor and connector, ensuring proper seating.
Step 7: Clear codes with scanner and test drive.
Addressing ABS and traction control sensor issue problems often starts with cleaning or replacing wheel speed sensors, which are common failure points.
This DIY approach is particularly effective for ABS and traction light on due to bad wheel speed sensor situations where dirt or metal particles have accumulated on the sensor.
After completing a brake job, you might experience ABS and traction light after brake job issues if the sensors were disturbed during the repair process.
Addressing Electrical Connection Problems
Common electrical fixes include:
- Cleaning battery terminals with baking soda solution
- Checking and tightening ground connections
- Inspecting fuses related to ABS (check owner’s manual for locations)
- Applying dielectric grease to electrical connectors
- Repairing damaged wiring with proper automotive wire
- Securing loose connectors with zip ties or electrical tape
Electrical issues are among the most common reasons ABS and traction lights turn on, particularly in older vehicles or those exposed to harsh environments.
For ABS and traction light on fix approaches related to electrical problems, always start with the simplest connections before moving to more complex components.
If you notice ABS and traction light car won’t start situations, this could indicate a more serious electrical problem affecting multiple systems.
Brake Fluid Level and Quality Check
Step 1: Locate the brake fluid reservoir (usually near the firewall on the driver's side).
Step 2: Check fluid level against "MIN" and "MAX" markings.
Step 3: Inspect fluid color - should be clear to amber (dark brown indicates contamination).
Step 4: If low, add DOT-specified brake fluid (check manual for correct type).
Step 5: Inspect for leaks around master cylinder, brake lines, and at each wheel.
Step 6: If fluid was low, bleed brakes to remove air from the system.
Low fluid levels can trigger ABS and traction light on due to low brake fluid warnings, which is a relatively simple fix if there are no leaks in the system.
Regular fluid checks can prevent ABS brake light and traction control light on situations from developing in the first place.
Remember that brake fluid absorbs moisture over time, which can lead to corrosion within the system and eventual ABS and traction light due to bad ABS module problems.
When to Seek Professional Help for ABS and Traction Control Problems
Seek professional help with multiple warning lights, abnormal brake pedal feel, pulling during braking, strange noises, fluid leaks, or failed reset attempts. Complex ABS module issues require specialized equipment.
Situations requiring professional intervention:
- Multiple warning lights illuminated simultaneously
- Brake pedal feels different (too hard, too soft, or pulsating)
- Vehicle pulls to one side during braking
- Strange noises (grinding, clicking) from the brake system
- Visible fluid leaks

GM Vehicles: EBCM Issues and Solutions
General Motors vehicles frequently experience EBCM (Electronic Brake Control Module) failures, particularly in Chevrolet, GMC, and Cadillac models.
Internal circuit board solder cracks are a common cause, sometimes fixable by specialized repair services rather than full replacement.
Many GM vehicles require a specific relearn procedure after EBCM replacement or battery disconnection, which affects how to reset ABS and traction control light procedures.
GM’s complex integration of braking systems means that ABS and traction control light on fix approaches often require dealer-level diagnostic equipment.
People Also Ask:
Why do my ABS and traction control lights come on in wet weather?
Water can infiltrate wheel speed sensors or connectors, causing intermittent signals. Splashing through puddles may temporarily trigger these lights if water reaches sensitive components. The systems may also activate more frequently in wet conditions as they work harder to maintain traction.
Can low tire pressure cause ABS and traction control lights to illuminate?
Yes, significantly underinflated tires rotate at different speeds than properly inflated ones, confusing wheel speed sensors. This can trigger both ABS and traction control lights as the system detects abnormal wheel speed differences.
How much does it typically cost to fix ABS and traction control problems?
Repair costs range from $150-300 for a wheel speed sensor replacement to $1,000-2,500 for an ABS module or pump replacement. Diagnostic fees typically run $75-150, while simple electrical repairs might cost $100-300.
Will a bad wheel bearing trigger both ABS and traction control lights?
Yes, a failing wheel bearing can cause irregular wheel speed readings since the speed sensor often mounts near or within the bearing assembly. As the bearing wears, it creates excessive movement that affects sensor readings.
Does the check engine light relate to ABS and traction control warnings?
Sometimes. While these systems operate independently, modern vehicles share data across multiple computers. Engine performance issues can affect electrical system voltage or computer communications, triggering multiple warning lights.
Can I pass a vehicle inspection with ABS and traction control lights on?
This depends on your location. Many states include ABS in safety inspections, while others don’t. Even in states without ABS requirements, emissions testing may fail if multiple warning lights are illuminated.
What’s the difference between the brake light and ABS light on the dashboard?
The regular brake warning light indicates issues with the hydraulic braking system (low fluid, engaged parking brake, or pressure loss). The ABS light specifically indicates a problem with the anti-lock braking system.
Are aftermarket brake parts compatible with ABS and traction control systems?
Quality aftermarket parts are generally compatible, but low-quality components may cause issues. Always use brake parts that meet or exceed OEM specifications, especially for components that interact with ABS sensors.
