TROUBLE DIAGNOSES FOR SYMPTOMS
Revision: June 20062007 Versa
Long Stopping DistanceEFS006LY
1. CHECK BASE BRAKING SYSTEM PERFORMANCE
1. Disable ABS by disconnecting ABS actuator and electric unit (control unit) connector.
2. Drive vehicle and check brake operation.
NOTE:

Stopping distance may be longer than vehicles without ABS when road condition is slippery.

Driving the vehicle with the ABS actuator and electric unit (control unit) disconnected may induce DTCs
in electrical control units using CAN communication. After the inspection, clear all DTCs. Refer to LAN-
4, "SYSTEM DESCRIPTION" .
OK or NG
OK >> Go to BRC-30, "ABS Works Frequently" .
NG >> Perform Basic Inspection. Refer to BRC-17, "
Basic Inspection" .
ABS Does Not WorkEFS006LZ
CAUTION:
The ABS does not operate when the vehicle speed is 10 km/h (6 MPH) or less.
1. CHECK WARNING LAMP ACTIVATION
Turn ignition switch ON and check for warning lamp activation.

Warning lamp should activate for approximately 2 seconds after turning the ignition switch ON.
OK or NG
OK >> Carry out self-diagnosis. Refer to BRC-20, "SELF-DIAGNOSIS" .
NG >> Go to BRC-17, "
ABS WARNING LAMP INSPECTION" .
Pedal Vibration or ABS Operation NoiseEFS006M0
NOTE:
During ABS activation, pedal vibration may be felt and a noise may be heard. This is normal and does not indi-
cate a malfunction.
1. CHECK SYMPTOM
1. Apply brake.
2. Start engine.
Does the symptom occur only when engine is started?
YES >> Carry out self-diagnosis. Refer to BRC-20, "SELF-DIAGNOSIS" .
NO >> GO TO 2.
2. RECHECK SYMPTOM
Does the symptom occur only when electrical equipment switches (such as headlamps) are turned on?
YES >> Check for radio, antenna or related wiring that is routed too close to the ABS actuator and electric
unit (control unit) and reroute as necessary.
NO >> Go to BRC-30, "
ABS Works Frequently" .

NOTE:
The top portion of the figure (front side) shows view from LH side of vehicle. RH side is the mirror image.
REMOVAL
Pay attention to the following when removing wheel sensor.
CAUTION:

As much as possible, avoid rotating wheel sensor when removing it. Pull wheel sensors out with-
out pulling on sensor harness.

Take care to avoid damaging wheel sensor edges or rotor teeth. Remove wheel sensor first before
removing front or rear wheel hub. This is to avoid damage to wheel sensor wiring and loss of sen-
sor function.
INSTALLATION
Pay attention to the following when installing wheel sensor. Tighten installation bolts and nuts to the specified
torques.

When installing, make sure there is no foreign material such as iron chips on and in the mounting hole of
the wheel sensor. Make sure no foreign material has been caught in the sensor rotor. Remove any foreign
material and clean the mount.

When installing front wheel sensor, press rubber grommets of strut bracket and body all the way in until
they get locked, and be careful not to apply a twist to harness. Harness should not be twisted after instal-
lation. (Install it with harness paint mark on body side grommet facing front of vehicle, and the strut side
grommet facing outside of vehicle.)

Removal and InstallationEFS006L6
CAUTION:

Before servicing, disconnect battery cables.

To remove brake tube, use flare nut wrench to prevent flare nuts and brake tube from being dam-
aged. To install, use flare nut torque wrench, tighten flare nut to the specified torque. Refer to BR-
11, "Hydraulic Circuit" .

Do not apply excessive impact to ABS actuator and electric unit (control unit), such as dropping it.

Do not remove and install actuator by holding harness.

After work is completed, bleed air from brake tube and hose. Refer to BR-10, "Bleeding Brake Sys-
tem" .
REMOVAL
1. Disconnect ABS actuator and electric unit (control unit) connector.
2. Loosen brake tube flare nuts, then remove brake tubes from ABS actuator and electric unit (control unit).
3. Remove brake booster hose from engine. Refer to BR-22, "
Removal and Installation" .

PRECAUTIONS
Revision: June 20062007 Versa
PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
ECS00GVW
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WAR NIN G:

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Service Notice or PrecautionsECS00FST

Use recommended brake fluid when adding fluid to the clutch reservoir tank. Refer to MA-11,
"RECOMMENDED FLUIDS AND LUBRICANTS".

Never reuse fluid drained from clutch system.

Be careful not to splash brake fluid on painted areas.

Use new brake fluid to clean or wash all parts of master cylinder and operating cylinder.

Never use mineral oils such as gasoline or kerosene. It will ruin the rubber parts of the hydraulic
system.

If transaxle assembly is removed from the vehicle, always replace CSC (Concentric slave cylin-
der). Return CSC to original position to remove transaxle assembly. Dust on clutch disc sliding
parts may damage CSC seal and may cause clutch fluid leakage.

Do not disassemble clutch master cylinder and CSC.
WAR NIN G:
After cleaning clutch disc, clean it with a dust collector. Do not use compressed air.
