The Supplemental Restraint System such as AIR BAG” and SEAT BELT PRE-TENSIONER”, used along, with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger certain, system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front, air bag, depending on the severity of a collision and whether the front occupants belted unbelted.
Information necessary to service the system safely is included in the SRS and SB section Service Manual, to avoid rendering the SRS inoperative, which could increase the risk of personal injury death, improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system, do not use electrical test equipment on any circuit related to the SRS unless instructed.
Refer to "RECOMMENDED FLUIDS AND LUBRICANTS" recommended brake fluid, be careful not to splash brake fluid on painted areas; it may cause paint damage, splashed on painted areas, wash it away with water immediately, to clean or wash all parts of master cylinder and disc brake caliper, use clean brake fluid.
Never use mineral oils such as gasoline or kerosene, use flare nut wrench when removing installing brake, if a brake fluid leak is found, the part must be disassembled, turn the ignition switch OFF and remove connector.
The ABS actuator and electric unit (control unit) or the battery terminal before performing work, always torque brake lines when installing, burnish the brake contact surfaces after refinishing, replacing rotors, after replacing pads, or soft pedal.
Clean brake pads and shoes with a waste cloth, then wipe with dust collector, during ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard, just after starting the vehicle, the brake pedal may vibrate or motor operating noises may be heard, stopping distance may be longer than that of vehicles without ABS when vehicle drives rough, gravel.
Or snow-covered (fresh, deep snow) roads, when an error is indicated by ABS or another warning lamp, collect all necessary information from customer (what symptoms are present under what conditions) and check for simple causes before starting, if incorrect tire sizes or types are installed on the vehicle or brake pads are not Genuine NISSAN parts, stopping distance or steering stability may deteriorate.
If there is a radio, antenna or related wiring near the control module, ABS function may have malfunction, if aftermarket parts (car stereo, CD player, etc, pinches, open circuits improper wiring, do not apply voltage of 7.
Maximum open terminal voltage of tester in use must be less than 7, before checking harnesses, turn ignition switch OFF and disconnect battery negative cable, area to be repaired must be soldered wrapped with tape, make sure that fraying of twisted wire is within 110 mm (4.
Do not make a bypass connection to repaired area, is bypassed, characteristics of twisted wire will be lost, the actual shapes of Kent-Moore tools may differ from those of special service tools illustrated here, checking operation of ABS active wheel sensors.
The Anti-Lock Brake System detects wheel revolution while braking and improves handling stability during, sudden braking by electrically preventing wheel lockup, if the electrical system malfunctions, the Fail-Safe function is activated, the ABS becomes inoperative.
