How to Perform Trouble Diagnoses for Quick and Accurate RepairEFS006LI
INTRODUCTION
The ABS system has an electronic control unit to control major func-
tions. The control unit accepts input signals from sensors and con-
trols actuator operation. It is also important to check for air leaks in
the booster or brake and vacuum lines, lack of brake fluid, or other
malfunctions in the brake system.
It is much more difficult to diagnose a malfunction that occurs inter-
mittently rather than continuously. Most intermittent conditions are
caused by poor electrical connections or damaged wiring. In this
case, careful checking of suspicious circuits may help prevent the
replacement of good parts.
A visual check only may not find the cause of the malfunction, so a
road test should be performed.
Before undertaking actual checks, take just a few minutes to talk with
a customer who approaches with an ABS complaint. The customer
is a very good source of information, especially for intermittent condi-
tions. Through the talks with the customer, find out what symptoms
are present and under what conditions they occur.
Start your diagnosis by looking for “conventional” malfunctions first.
This is one of the best ways to troubleshoot brake malfunctions on
an ABS equipped vehicle. Also check related Service Bulletins for
information.

INSPECTION PROCEDURE
1. CONNECTOR INSPECTION
Disconnect the ABS actuator and electric unit (control unit) connector E33 and wheel sensor of malfunctioning
code.
Check the terminals for deformation, disconnection, looseness or damage.
OK or NG
OK >> GO TO 2.
NG >> Repair or replace as necessary.
2. CHECK WHEEL SENSOR OUTPUT SIGNAL
1. Connect ABS active wheel sensor tester (J-45741) to wheel sensor using appropriate adapter.
2. Turn on the ABS active wheel sensor tester power switch.
NOTE:
The green POWER indicator should illuminate. If the POWER indicator does not illuminate, replace the
battery in the ABS active wheel sensor tester before proceeding.
3. Spin the wheel of the vehicle by hand and observe the red SENSOR indicator on the ABS active wheel
sensor tester. The red SENSOR indicator should flash on and off to indicate an output signal.
NOTE:
If the red SENSOR indicator illuminates but does not flash, reverse the polarity of the tester leads and
retest.
Does the ABS active wheel sensor tester detect a signal?
YES >> GO TO 3.
NO >> Replace the wheel sensor. Refer to BRC-33, "
Removal and Installation" .
3. CHECK TIRES
Check for inflation pressure, wear and size of each tire. Refer to WT-29, "
SERVICE DATA AND SPECIFICA-
TIONS (SDS)" .
Are tire pressure and size correct and is tire wear within specifications?
YES >> GO TO 4.
NO >> Adjust tire pressure or replace tire(s).
4. CHECK WHEEL BEARINGS
Check wheel bearing axial end play. Refer to FAX-5, "
FRONT WHEEL BEARING INSPECTION" or RAX-4,
"REAR WHEEL BEARING INSPECTION" .
OK or NG
OK >> GO TO 5.
NG >> Repair or replace as necessary. Refer to FAX-5, "
Removal and Installation" or RAX-4, "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.
