Precaution for Brake Control

During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is normal.
Just after starting the vehicle, the brake pedal may vibrate or motor operating noises may be heard from engine compartment. This is normal due to the self check operation.
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 diagnosis.
Besides electrical system inspection, check brake booster operation, brake fluid level, and fluid leaks.
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 a malfunction or error.
If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness pinches, open circuits or improper wiring.
