RODA SERVICE
Diagnose Anti-Lock Brake (ABS) Concern
Your vehicle’s Anti-Lock Brake System (ABS) helps you stop safely and maintain control during hard braking or slippery conditions. When the ABS warning light turns on — or if braking feels inconsistent — it means your system needs attention.

When You Need This
ABS issues can show up in different ways — sometimes subtle, sometimes obvious — but they always deserve prompt inspection.
ABS or Traction Control Light On
The most common symptom — it means the system detected a fault, often from a sensor or wiring issue. Even if braking feels normal, your anti-lock safety function may not be active.
Pulsing or Vibration During Braking
Light pulsing can be normal, but sudden or constant vibration may indicate uneven sensor readings or tone ring damage.
Longer Stopping Distances on Wet Roads
Without proper ABS function, the wheels can lock up more easily under heavy braking, especially on slippery surfaces.
Inconsistent Brake Feel
Pedal pressure that changes from one stop to the next can signal trapped air, a weak pump, or a failing hydraulic modulator.

⚠️ What happens if you skip it? ⚠️
Driving with a faulty ABS means your car’s anti-lock safety function won’t work, especially on wet or icy roads. Regular braking will still operate, but without the control and stability ABS provides. Early diagnosis keeps your brakes safe and prevents sensor or module damage.
What It Could Be
ABS concerns can stem from electrical faults, mechanical wear, or hydraulic problems. Common causes include:
• Faulty Wheel Speed Sensor
A dirty or failed sensor sends incorrect signals, triggering the ABS light and disabling the system’s safety assist.
• Wiring or Connector Issue
Corroded or damaged connectors interrupt sensor signals, causing intermittent or false warnings.
• ABS Pump or Modulator Failure
These components regulate brake pressure during ABS engagement; if they fail, you may notice pulsing or uneven braking.
• ABS Control Module Fault
The control unit that manages ABS can fail internally, preventing communication with the system or triggering dashboard warnings.
• Dirty or Cracked Tone Ring
Rust or dirt on the tone ring causes inaccurate wheel speed readings, making the ABS engage unnecessarily.
How This is Done
We perform a structured diagnostic that combines inspection, electronic testing, and real-world verification.
1. Scan for Fault Codes
Identify ABS or traction control system errors using a professional diagnostic scanner.
2. Inspect Sensors & Wiring
Examine sensors, tone rings, and connectors for damage or debris.
3. Check Hydraulic System
Test the ABS pump and modulator for proper pressure and operation.
4. Perform Live-Data Road Test
Monitor wheel speed readings and system response during braking.
5. Explain Findings Clearly
Review findings and credit the diagnostic toward any approved service.

“Roda was a great service. I hit a pothole and had a blow out. They came and picked the car up downtown, fixed it, and dropped it back at my house. I'll definitely check them out again.”
