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 ABS actuator and electric unit (control unit) mounting nuts.
4. Remove ABS actuator and electric unit (control unit) from vehicle.
CAUTION:
Be careful of the following when removing ABS actuator and electric unit (control unit).

If the part number on the part number label (pasted on actuator upper surface) is the same, ABS
actuator and electric unit (control unit) cannot be used on another vehicle.
If it is used on another vehicle, ABS warning lamp, SLIP indicator lamp and VDC OFF indicator
lamp may turn ON or VDC/TCS/ABS may not operate normally.
When replacing ABS actuator and electric unit (control unit), must use new service parts.

Before servicing, disconnect battery cables.

To remove brake tube, use a flare nut torque wrench to prevent flare nuts and brake tube from
being damaged. To install, use a flare nut torque wrench (commercial service tool) and tighten
with the specified torque.

Do not apply excessive impact to actuator, such as dropping it.

Do not remove and install ABS actuator and electric unit (control unit) by holding harness.
INSTALLATION
Install is in the reverse order of the removal.
CAUTION:
Be careful of the following when installing ABS actuator and electric unit (control unit).

Tighten the mounting bolts and nuts with the specified torque.

After the work, bleed air from brake piping. Refer to BR-10, "Bleeding Brake System" .

After installing body harness connector in the actuator, make sure connector is securely locked

When replacing ABS actuator and electric unit (control unit), calibrate Steering angle sensor neu-
tral position. Refer to BRC-40, "
Adjustment of Steering Angle Sensor Neutral Position" .

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BBS0059V
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:

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.
Precautions for Liquid GasketBBS005AV
REMOVAL OF LIQUID GASKET SEALING

After removing mounting nuts and bolts, separate the mating
surface using seal cutter (SST) and remove old liquid gasket
sealing.
CAUTION:
Be careful not to damage the mating surfaces.

Tap seal cutter to insert it, and then slide it by tapping on the
side as shown in the figure.

In areas where seal cutter (SST) is difficult to use, use plastic
hammer to lightly tap the parts, to remove it.
CAUTION:
If for some unavoidable reason tool such as screwdriver is
used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using scraper, remove old liquid gasket adhering to the liquid
gasket application surface and the mating surface.

Remove liquid gasket completely from the groove of the liquid
gasket application surface, mounting bolts, and bolt holes.
2. Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to tube presser (SST).
Use Genuine Liquid Gasket or equivalent.
4. Apply liquid gasket without breaks to the specified location with
the specified dimensions.

If there is a groove for the liquid gasket application, apply liq-
uid gasket to the groove.

[QR]
PRECAUTIONS


As for the bolt holes, normally apply liquid gasket inside the
holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of service manual.

Within 5 minutes of liquid gasket application, install the mating
component.

If liquid gasket protrudes, wipe it off immediately.

Do not retighten mounting bolts or nuts after the installation.

After 30 minutes or more have passed from the installation, fill
engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe them.

InspectionBBS005A2
LEVEL CHECK

Check if the reservoir tank engine coolant level is within the
“MIN” to “MAX” range when engine is cool.

Adjust the engine coolant level as necessary.
LEAK CHECK

To check for leaks, apply pressure to the cooling system with
radiator cap tester (commercial service tool) and radiator cap
tester adapter (SST).
WARNING:
Do not remove radiator cap when engine is hot. Serious
burns could occur from high-pressure engine coolant
escaping from radiator.
CAUTION:
Higher testing pressure than specified may cause radiator
damage.
NOTE:
In a case that engine coolant decreases, replenish radiator with engine coolant.

If anything is found, repair or replace damaged parts.
Changing Engine CoolantBBS005A3
WARNING:

To avoid being scalded, do not change engine coolant when engine is hot.

Wrap a thick cloth around radiator cap and carefully remove the cap. First, turn the cap a quarter
of a turn to release built-up pressure. Then turn the cap all the way.

Be careful not to allow engine coolant to contact drive belt.
DRAINING ENGINE COOLANT
1. Remove grommet from undercover.
2. Open radiator drain plug at the bottom of radiator, and then remove radiator cap.
When drain all of engine coolant in the system, open water drain plug on engine cylinder block.
Refer to EM-81, "
CYLINDER BLOCK" .
3. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing.
