Frequently Asked Questions
- Is driving without ABS safe?
- You still have normal brakes. ABS prevents wheel lockup during hard braking. Drive more carefully in rain/snow until fixed.
- Can I clean a wheel speed sensor?
- Yes — metal shavings from brake dust can accumulate on the magnetic sensor tip. Cleaning sometimes fixes the code.
