ABS Repair & Diagnostics in Phoenix, AZ
When the ABS light comes on the system usually switches itself off, which means your normal brakes still work but the anti-lock function does not. That matters most in exactly the conditions you cannot plan for, so it is worth reading the code rather than living with the light.
Signs You Need ABS Repair Service
- An ABS warning light, on its own or with traction control
- The brake pedal pulsing when it should not
- ABS engaging at low speed on dry roads
- Traction or stability control disabled at the same time
- A wheel locking under hard braking
What We Do
- Read the ABS codes and live wheel speed data, since the fault is usually one sensor and the code names it
- Inspect wheel speed sensors, their rings and their wiring, which is where most ABS faults actually are
- Check for the wheel bearing play that throws the sensor signal out, because that is a common root cause
- Replace sensors, rings or the ABS module where testing calls for it
- Clear codes and confirm the system self-tests clean on a road test
How We Diagnose It
The order matters. Most of these steps exist to rule out a cheaper cause before anyone quotes you the expensive one.
- Read the ABS codes, which on most vehicles name the corner directly rather than leaving it to guesswork.
- Compare live wheel speed data from all four wheels while driving, which shows the sensor that is dropping out.
- Inspect the sensor, the tone ring and the wiring at that corner. Corrosion and road debris on the ring are common and cost nothing to clean.
- Check the wheel bearing for play, because a bearing with play changes the sensor gap and is frequently the real cause of a sensor code.
- Check the brake fluid level and the base brake system, since a low fluid warning and an ABS warning often appear together for unrelated reasons.
- Clear the codes and confirm the system self-tests clean on a road test rather than assuming.
What Drives the Cost
We are not going to put a price on this page, because the honest answer depends on your vehicle and we would rather quote you than guess in public. These are the things that actually move the number, so you know what we are looking at.
- A sensor, a tone ring, wiring, or the ABS module itself, which span a very wide range.
- Whether the sensor is separate or built into the wheel hub assembly.
- Whether a wheel bearing is the underlying cause and needs doing anyway.
- Whether the module needs programming to the vehicle after replacement.
- How many corners are involved.
What Happens If You Wait
Your normal brakes still work with the ABS light on, so this is not the emergency the dashboard makes it look like. What you have lost is the anti-lock function, and usually traction and stability control with it, in exactly the conditions you cannot plan for: a wet road, gravel, a sudden stop. It is a read-the-code-soon item rather than a stop-driving item.
