Basic InspectionNFS00037
BRAKE FLUID AMOUNT, LEAKS, AND BRAKE PADS INSPECTION
1. Check fluid level in the brake reservoir tank. If fluid level is low, refill the brake fluid.
2. Check brake tubes or hoses and around ABS actuator and electric unit (control unit) for leaks. If there is
leaking or oozing fluid, check the following items.
If ABS actuator and electric unit (control unit) connection is loose, tighten the piping to the specified
torque and re-conduct the leak inspection to make sure there are no leaks.
If there is damage to the connection flare nut or ABS actuator and electric unit (control unit) screw,
replace the damaged part and re-conduct the leak inspection to make sure there are no leaks.
When there is fluid leaking or oozing from a part other than ABS actuator and electric unit (control unit)
connection, if the fluid is just oozing out, use a clean cloth to wipe off the oozing fluid and re-check for
leaks. If fluid is still oozing out, replace the damaged part.
When there is fluid leaking or oozing at ABS actuator and electric unit (control unit), if the fluid is just
oozing out, use a clean cloth to wipe off the oozing fluid and re-check for leaks. If fluid is still oozing out,
replace the ABS actuator and electric unit (control unit) body.
CAUTION:
ABS actuator and electric unit (control unit) cannot be disassembled.
3. Check brake pad degree of wear. Refer to BR-26, "
PAD WEAR INSPECTION" in “Front Disc Brake” and

Precautions for Brake ControlNFS0003T
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 error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (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 the following components are replaced with non-genuine components or converted, the VDC OFF indi-
cator lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Compo-
nents related to suspension (Shock Absorber, Strut, Spring, Bush, 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 the suspension, tires or components related to
the brakes may cause the VDC OFF indicator lamp and the SLIP indicator lamp to 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 if the
brake pedal is used. 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 the VDC warning lamp may turn on.
However, this is not a problem if normal operation can be resumed after restarting the engine.
Sudden turns (such as spin turns, acceleration turns), drifting, etc. When VDC function is OFF (VDC SW
ON) may cause the yaw rate/side G -sensor system indicate a problem. However this is not a problem if
normal operation can be resumed after restarting the engine.

TROUBLE DIAGNOSIS
Revision: 2006 November2007 350Z
Note 1: After completing repairs of the shorted sensor circuit, when ignition switch is turned ON, ABS warning lamp turns on. Check that
ABS warning lamp turns off while driving the vehicle at approximately 30 km/h (19 MPH) for approximately 1 minute according to self-
diagnosis procedure. In addition, if wheel sensor 2 is displayed for the wheels, check the wheel sensor circuit and also check the control
unit power voltage.

TROUBLE DIAGNOSIS
Revision: 2006 November2007 350Z
When inspection of the continuity or voltage between units is performed, check connector terminals for
disconnection, looseness, bend, or collapse. If any non-standard condition is detected, repair or replace
applicable part.
Intermittent errors may be caused by a poor connection in the harness, connector, or terminal. Move har-
nesses, harness connectors, or terminals by hand to make sure all connections are solid and undamaged.
If a circuit tester is used for the check, be careful not to forcibly extend any connector terminal.
VDC/TCS/ABS is a system that uses electronic control to perform brake control and engine power control.
Therefore, phenomena like those shown in the following table may occur, but this is because the system is
working normally.
Symptom Symptom description Result
Motor operation noiseThe is a motor operation sound inside VDC/TCS/ABS actuator, and some-
times there is a slight sound when VDC, TCS, or ABS operates.
Normal
Just after the engine starts, the motor operating noise may be heard. This
is a normal status of the system operation check.
System operation check noiseWhen the engine is started, you may barely be able to hear a slight thud-
ding sound from the engine room, but this sound is made by the system
operation check and is normal.Normal
TCS operation
(SLIP indicator lamp ON)TCS may be activated any time the vehicle suddenly accelerates, suddenly
downshifts, or is driven on a road with a varying surface friction coefficient.
Normal
Cancel the VDC/TCS
function for the
inspection on a chas-
sis dynamometer. When inspecting the speedometer, etc., press VDC OFF switch to turn off
TCS function before conducting the work.
When accelerator pedal is depressed on a chassis dynamometer (front
wheel fixing type), the vehicle speed will not increase. This is normal,
because TCS is activated by the stationary front wheels. The warning lamp
may also turn on to show “sensor system error” in this case. This is not a
malfunction either, because the stationary front wheels are detected.
Restart engine, and drive the vehicle at 30 km/h (19 MPH) or higher to
check that the warning lamp no longer turns on.
ABS operation
(longer stopping distance)Stopping distance may be longer for vehicles with ABS when the vehicle
drives on rough or snow-covered roads. Use lower speeds when driving on
these kinds of roads.Normal
Sluggish feelDepending on road circumstances, the driver may have a sluggish feel.
This is normal, because under TCS operation optimum traction has the
highest priority (safety first). Sometimes the driver has a slight sluggish feel
in response to substantial accelerator pedal operation.Normal
