Precautions for Brake Control

Just after starting vehicle after 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.
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 oil 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, 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 non-standard suspension parts (shock absorber, strut, spring, bushing, etc.) and reinforcements (roll bar, tower bar, etc.) are attached, or if suspension parts deteriorate significantly, VDC may not operate normally, VDC OFF indicator lamp and SLIP indicator lamp may turn on.
If non-standard engine components (muffler, etc.) are attached, VDC may not operate normally, VDC OFF indicator lamp and SLIP indicator lamp may turn on.
