RIDEX 2254S0014 ABS sensor ring

Description

A Nissan ABS ring, also known as an ABS sensor ring or tone ring, is a crucial component of the Anti-lock Braking System (ABS) in your Nissan vehicle. Here’s a brief description:

Function:

• The ABS ring is a gear-shaped or ringed component attached to the wheel hub or axle.
• As the wheel rotates, the ABS ring spins with it, passing a magnetic sensor located nearby.
• The sensor detects the changes in the teeth or grooves of the ring, generating a signal that conveys the wheel speed information to the ABS control unit.

Importance:

• This wheel speed information is crucial for the ABS system to function properly.
• By monitoring individual wheel speeds, the ABS can detect potential lockup situations during hard braking.
• When a wheel is about to lock, the ABS control unit utilizes the ABS pump to modulate the brake pressure at that specific wheel, preventing skidding and maintaining steering control.

Materials and location:

• ABS rings are typically made of metal or plastic and are located near the wheel hub or axle, where the sensor can easily detect its rotation.

Signs of a Faulty ABS Ring:

• ABS warning light on the dashboard stays lit.
• Erratic ABS activation during braking.
• Reduced braking performance due to faulty ABS information.

Important Notes:

• A damaged or faulty ABS ring can significantly compromise the effectiveness of your ABS system.
• If you suspect an issue with your ABS ring, it’s crucial to consult a qualified mechanic for diagnosis and repair.
• Replacing an ABS ring can vary in complexity and cost depending on the specific Nissan model.
• Always refer to your owner’s manual for specific information about your Nissan model and its ABS system.
