When the lights are on, your Chevy is signaling that the entity isn’t working correctly. But what’s the cause? In many cases, the culprit is either a wheel speed sensor defeat or a damaged circuitry link.
Let’s break down how these systems work, the manifestations of each type of failure, and how technicians for Auto Repair in Bend, OR diagnose the legitimate root of the problem.
Why ABS & Traction Control Lights Come On Together
Your Chevy’s ABS and Traction Control systems share the same network of sensors and circuitry. When one part abandons, both schemes may become incapacitated for safety reasons. A warning light doesn’t always mean an immediate crisis, but it does indicate that your cab’s stability and braking efficiency may be imperiled.
Common issues include:
- Failing wheel speed sensors
- Broken or rusted wiring
- Dirty or broken tone rings
- Faulty ABS modules
- Poor electrical estates or low voltage
Among these, sensor failure and circuitry damage are by far ultimate common causes.
Signs of a Failing Wheel Speed Sensor
A distressing sensor often establishes very noticeable manifestations, including:
• Strange ABS Pulsing
During braking, the ABS may activate when it shouldn’t—or fail to activate when wanted.
• Speedometer Fluctuations (in rare cases)
Some Chevy models use speed sensors to help calculate car speed.
• Trouble Codes Stored in the Computer
A diagnostic scan by experts like Davis & Clark Auto Repair will often disclose codes relating to specific wheel positions.
How Wiring Damage Can Cause the Same Symptoms
Sometimes the sensor itself is fine—it’s the wiring associated with it that causes the failure. Wiring issues are intensely common in environments with:
- Road seasoning
- Heavy rain
- Gravel roads
- Temperature extremes
- Off-highway driving
The wiring is exposed under the vehicle and may be torn, eroded, pinched by waste, or simply worn over time.
Signs of Wiring or Connector Issues
- Lights enter only when driving over bumps
- Symptoms worsen in wet weather
- Intermittent ABS/traction control activation
- “Open circuit” or “low service” trouble codes
- Visible damage when examining harnesses
Wiring problems may be harder to detect without proper diagnostic tools, which is why technicians frequently perform a particularized electrical test before replacing any parts.
How Technicians Diagnose the True Cause
Since both questions create almost identical syndromes, mechanics use a gradual process to identify the main idea.
1. Scanning the Vehicle
Diagnostic tools tell error codes firm to specific sensors or circuits.
2. Inspecting Wheel Hubs
Technicians like Davis & Clark Auto Repair check for waste, metal bits, or damage to the spirit rings.
3. Testing Sensor Voltage
A multimeter helps determine whether the sensor is sending correct signals.
4. Checking Wiring Continuity
The wiring harness is proven from the sensor to the ABS module for breaks or corrosion.
Conclusion
With proper disease and timely repair, you’ll replace safe braking conduct and thorough traction control functionality, helping your Chevy stay responsible in all weather conditions.
