Precautions for Brake Control

During VDC/TCS/ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
Just after starting vehicle after turning ignition switch ON, brake pedal may vibrate or motor operating noise may be heard from engine room. 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.
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 diagnostic servicing. Besides electrical system inspection, check booster operation, brake fluid level, and fluid leaks.
If tire size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts, stopping distance or steering stability may deteriorate.
If there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, VDC/TCS/ABS function may have a malfunction or error.
If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness pinches, open circuits, and improper wiring.
If the following components are replaced with non-genuine components or converted, VDC OFF indicator lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Components related to suspension (shock absorber, strut, spring, bushing, etc.), Tires, wheels (exclude specified size), components related to brake (pad, rotor, caliper, etc.), components related to engine (muffler, ECM, etc.), components related to body reinforcement (roll bar, tower bar, etc.).
Driving in the condition of breakage or excessive wear of suspension, tires or components related to the brakes may cause VDC OFF indicator lamp and SLIP indicator lamp turn on, and the VDC system may not operate properly.
When the TCS or VDC is activated by sudden acceleration or sudden turn, some noise may occur. The noise is a result of the normal operation of the TCS and VDC.
When driving on roads which have extreme slopes (such as mountainous roads) or high banks (such as sharp carves on a freeway), the VDC may not operate normally, or VDC OFF indicator lamp and SLIP indicator lamp may turn on. However, this is not a malfunction, if normal operation can be resumed after restarting engine.
Sudden turns (such as spin turns, acceleration turns), drifting, etc. When VDC function is OFF (VDC OFF SW ON) may cause the G sensor system indicate a malfunction. However, this is not a malfunction, if normal operation can be resumed after restarting engine.
Change 4 tires at a time. Be sure to use specified-size tires that have the same brand name and pattern. Wheel sensor errors can be detected be self-diagnosis when tires have wide abrasion variations or the size is different from the genuine tires.
