Brake system is an important safety part. If a brake fluid leak is
detected, always disassemble the affected part. If a malfunction
is detected, replace part with a new one.

Before working, turn ignition switch OFF and disconnect har-
ness connectors of ABS actuator and electric unit (control unit)
or battery cable from negative terminal.

When installing brake piping, be sure to check torque.
Precautions for Brake ControlEFS004FV

During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.

Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine compartment. 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 malfunction 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 start-
ing diagnostic servicing. Besides electrical system inspection, check booster operation, brake fluid level,
and oil leaks.

If tyre 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.

If aftermarket parts (car stereo, CD player, etc.) Have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.
