When a malfunction occurs that causes the ABS warning light to come on, it is necessary to gather information about the circumstances under which it occurred and assess the amount of diagnostic work to be done. Also, in addition to checking the electrical system, check the brake fluid level, oil leaks, brake booster operation, etc.
When the ABS system is operating, the brake pedal vibrates slightly and a mechanical noise may be heard. This is normal.
When starting the engine or immediately after starting, the brake pedal may vibrate. Motor noise may also be heard from the engine compartment. This is normal and indicates that a function test of the ABS system is being performed.
When driving on uneven, gravel or snowy (fresh deep snow) On roads, the stopping distance may be longer than for vehicles without ABS.
If you do not use genuine NISSAN brake pads and tires, the braking distance will increase and/or road holding will deteriorate.
When there is a radio communication equipment, an antenna and an antenna input near the control unit, interference and malfunctions may occur in the operation of the ABS system.
If additional units are installed at the rear of the vehicle (stereo system, CD player, etc.), After disconnecting the electrical wiring, check for mutual interference, correct wiring, etc.
