Sleep condition
Wake-up operation
 BCM transmits sleep wake up signal (wake up) to each unit when any condition listed below is established,
and then goes into normal mode from low power consumption mode.
 Each unit starts transmissions with CAN communication by receiving sleep wake up signals. Each unit trans-
mits wake up signals to BCM with CAN communication to convey the start of CAN communication.

PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001716907
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 SR and SB section of this Service Man-
ual.
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 performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR 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 har-
ness connectors.
Precaution for Brake SystemINFOID:0000000001716908
 Refill using recommended brake fluid. Refer to MA-19, "Fluids and Lubricants".
 Never reuse drained brake fluid.
 Be careful not to splash brake fluid on painted surface of body. If brake fluid is splashed on painted surfaces
of body immediately wipe it off with cloth and then wash it away with water.
 To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use new brake fluid.
 Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
 Use a flare nut wrench when removing a brake tube and use a
flare nut torque wrench when installing a brake tube.
 When installing brake tubes and hoses, be sure to check torque.
 Before working, turn ignition switch OFF and disconnect connec-
tors of ABS actuator and electric unit (control unit) or the battery
cable from the negative terminal.
 Burnish the new braking surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage. Refer toBR-26, "
Brake Burnishing" .

BRAKE FLUID
BRAKE FLUID
On Board InspectionINFOID:0000000001716919
CHECKING BRAKE FLUID LEVEL
 Make sure the fluid level in the reservoir tank is within the standard
(between MAX and MIN lines).
 Visually check around the reservoir tank for fluid leakage.
 If fluid level is excessively low, check brake system for fluid leak-
age.
 Release parking brake lever and see if brake warning lamp goes
off. If not, check brake system for fluid leakage.
Drain and RefillINFOID:0000000001716920
CAUTION:
 Refill using recommended brake fluid. Refer to MA-19, "
Fluids and Lubricants".
 Never reuse drained brake fluid.
 Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, immediately wipe them with cloth and wash it away with water.
 Before working, disconnect connectors of ABS actuator and electric unit (control unit) or battery
cable from the negative terminal.
1. Connect a vinyl tube to bleed valve.
2. Depress the brake pedal, loosen the bleed valve, and gradually
remove the brake fluid.
3. Clean inside of reservoir tank, and refill with new brake fluid.
4. Loosen bleed valve, depress brake pedal slowly to full stroke
and then release it. Repeat the procedure every 2 or 3 seconds
until the new brake fluid comes out, then close the bleed valve
while depressing the brake pedal. Repeat the same procedure
for each wheel.
5. Bleed air. Refer to BR-8, "
Bleeding Brake System" .
Bleeding Brake SystemINFOID:0000000001716921
CAUTION:
 While bleeding, pay attention to master cylinder fluid level.
 Before working, disconnect connectors of ABS actuator and electric unit (control unit) or the battery
cable from the negative terminal.
1. Connect a vinyl tube to the rear right bleed valve.
2. Fully depress brake pedal 4 to 5 times.
