ABS Light Glowing on Your Murano III? Here’s What to Check First

Why the ABS Light Stays On

If you're seeing that amber ABS warning constantly on your Nissan Murano III, it's your car's way of saying the anti-lock braking system has detected a fault. In my experience, the single most common culprit is a wheel speed sensor that has failed, gotten dirty, or has a damaged wire. Each wheel has one of these sensors, and even a slight disruption can trigger the light.

Likely Causes & Parts to Check

• Wheel speed sensors – The most frequent problem. Check the front and rear sensors for physical damage, metal shavings, or excessive dirt on the magnetic tip.
• Sensor wiring and connectors – Look for chafed, pinched, or corroded wires near the wheel well or suspension components. Often, a bad connection causes intermittent or continuous warning.
• Tone rings or bearing reluctor rings – The toothed ring that the sensor reads can crack or collect debris, especially on the rear hubs.
• Brake fluid level or ABS module – Less common, but a low fluid level or a failing ABS pump/module can also turn on the warning light.

Is It Safe to Drive?

Yes, you can usually drive cautiously with the ABS light on—your normal brakes will still work. However, do not rely on the anti-lock function during a panic stop or on slippery roads. The vehicle may also disable stability control, so drive with extra care and get the system checked as soon as possible.

Start by reading the fault codes with an OBD-II scanner, then inspect the sensors and wiring at all four wheels. If you're not comfortable crawling under, a reputable shop can diagnose it quickly. But knowing these likely culprits will save you time and money.
