2004 Infiniti FX45FACTORY OEM SERVICE PROCEDURE

Abs Function

  • The anti-lock brake system is a function that detects wheel revolution while braking, and it improves handling stability during sudden braking by electrically preventing 4 wheel lock. Maneuverability is also improved for avoiding obstacles.
  • If the electrical system breaks down, then the fail-safe function starts, the ABS becomes inoperative, and ABS warning lamp turns on.
  • Electrical system diagnosis by CONSULT-II is available.
  • During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
  • When starting engine, or just after starting vehicle, brake pedal may vibrate or motor operating noises may be heard from engine compartment. This is a normal status of operation check.
  • Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel, or snow-covered (fresh, deep snow) roads.
