Nissan Frontier: Active Brake Limited Slip (ABLS) system

• The Active Brake Limited Slip (ABLS) system in the Nissan Frontier is designed to enhance traction by automatically applying brake force to a slipping wheel and transferring power to the wheel on the same axle with better grip. This intelligent braking intervention helps the Nissan Frontier maintain forward motion on uneven, loose, or slippery surfaces where traction is compromised.
• On Nissan Frontier models equipped with 4-Wheel Drive, the ABLS system functions in both 4H and 4LO modes.

  When 4WD is engaged, the ABLS system actively manages traction across both front and rear axles, improving off-road capability and stability. In contrast, on 2-Wheel Drive Nissan Frontier models, the system operates only on the drive axle, ensuring efficient power distribution where it is needed most.

• The ABLS system in the Nissan Frontier is continuously active and requires no driver input. However, under certain operating conditions, the system may temporarily deactivate automatically to protect components. Even in such cases, normal braking performance remains unaffected. Additionally, the ABLS system continues to function independently even when the Vehicle Dynamic Control (VDC) system is switched off.
• The ABLS system will not engage if both wheels on the same drive axle lose traction simultaneously, as there is no stable wheel available to transfer torque to.

WARNING

• While the ABLS system in the Nissan Frontier improves traction, it cannot eliminate the risk of accidents caused by sudden steering inputs, excessive speed, or unsafe driving behavior. Always reduce speed and exercise extra caution when driving on slippery or unstable surfaces, especially when cornering.
• Do not modify the suspension system of your Nissan Frontier.

  If components such as shock absorbers, springs, struts, stabilizer bars, bushings, or wheels are not approved by Nissan or are excessively worn, the ABLS system may not function correctly.

  This may negatively impact handling performance and could trigger the slip indicator warning light.

• If brake components such as pads, rotors, or calipers are not Nissan-approved or are significantly worn, the ABLS system in the Nissan Frontier may operate improperly, and the slip indicator light may illuminate.
• Using non-recommended wheels or tires on the Nissan Frontier can interfere with proper ABLS operation and may also cause the slip indicator warning light to turn on.
