PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001703818
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.
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 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 har-
ness connectors.
Precaution for Brake SystemINFOID:0000000001703819
CAUTION:
• Refer to MA-10
for recommended brake fluid.
• 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, wash it away with water immediately.
• To clean or wash all parts of master cylinder and disc brake caliper, use clean brake fluid.
• Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic sys-
tem.
• Use flare nut wrench when removing and installing brake
tube.
• If a brake fluid leak is found, the part must be disassembled
without fail. Then it has to be replaced with a new one if a
defect exists.
• Turn the ignition switch OFF and remove the connector of the
ABS actuator and electric unit (control unit) or the battery ter-
minal before performing the work.
• Always torque brake lines when installing.
• Burnish the brake contact surfaces after refinishing or replac-
ing rotors, after replacing pads, or if a soft pedal occurs at
very low mileage. Refer to BR-28, "
Brake Burnishing Proce-
dure".
WARNING:
• Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.
Precaution for Brake ControlINFOID:0000000001703821
• During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.
• Just after starting the vehicle, the brake pedal may vibrate or motor operating noises may be heard from
engine compartment. This is normal due to the self check operation.
• Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel, or
snow-covered (fresh, deep snow) roads.

SYSTEM DESCRIPTION
System ComponentINFOID:0000000001703825
ABS FunctionINFOID:0000000001703826
• The Anti-Lock Brake System detects wheel revolution while braking and improves handling stability during
sudden braking by electrically preventing wheel lockup. Maneuverability is also improved for avoiding obsta-
cles during emergency braking.
• If the electrical system malfunctions, the Fail-Safe function is activated, the ABS becomes inoperative and
the ABS warning lamp turns on.
• The electrical system can be diagnosed using CONSULT-III.
• During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.
• Just after starting the vehicle, the brake pedal may vibrate or motor operating noises may be heard from the
engine compartment. This is normal due to the self check operation.
• Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel, or
snow-covered (fresh, deep snow) roads.
EBD FunctionINFOID:0000000001703827
• Electronic Brake Distribution is a function that detects subtle slippages between the front and rear wheels
during braking, and it improves handling stability by electronically controlling the brake fluid pressure which
results in reduced rear wheel slippage.
• If the electrical system malfunctions, the Fail-Safe function is activated, the EBD and ABS become inopera-
tive, and the ABS warning lamp and brake warning lamp are turned on.
• The electrical system can be diagnosed using CONSULT-III.
• During EBD operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.
• Just after starting the vehicle, the brake pedal may vibrate or motor operating noises may be heard from the
engine compartment. This is normal due to the self check operation.
Fail-Safe FunctionINFOID:0000000001703828
CAUTION:
If the Fail-Safe function is activated, perform the Self Diagnosis for ABS system.
ABS/EBD SYSTEM
In case of an electrical malfunction with the ABS, the ABS warning lamp will turn on. In case of an electrical
malfunction with the EBD system, the brake warning lamp and the ABS warning lamp will turn on.
The system will revert to one of the following conditions of the Fail-Safe function.
1. For ABS malfunction, only the EBD is operative and the condition of the vehicle is the same condition of
vehicles without ABS system.

< SERVICE INFORMATION >
PRECAUTIONS
• Be sure to turn the ignition switch OFF and disconnect the battery cable from the negative terminal
before any repair or inspection work. The open/short circuit of related switches, sensors, solenoid
valves, etc. will cause the MIL to light up.
• Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
• Be sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. may cause the MIL to light up due to a short circuit.
• Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to a malfunction of the EVAP system or fuel injection system, etc.
• Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
Service After Replacing TCM and Transaxle AssemblyINFOID:0000000001703427
SERVICE AFTER REPLACING TCM AND TRANSAXLE ASSEMBLY
Perform the applicable service in the following sheet when replacing TCM or transaxle assembly
CAUTION:
• Do not start the engine until the service is completed.
• “A/T C/U POWER SUPPLY [P1701]” may be indicated soon after replacing TCM or transaxle assem-
bly (after erasing the memory at the pattern B). Restart the self-diagnosis after erasing the self-diag-
nosis result. Check that no error is detected.
NOTE:
Old unit means that the unit has been already used for another vehicle.
PATTERN A
1. Shift the selector lever to “P” position after replacing TCM. Turn the ignition switch ON.
2. Check that the shift position indicator in the combination meter turns ON (It indicates approximately 1 or 2
seconds after turning the ignition switch ON.)
• Check the following items if the shift position indicator does not turn ON. Repair or replace the shift posi-
tion indicator if necessary.
- The harness between TCM and ROM ASSY in the transaxle assembly is open or short.
- Cable disconnected, loosen, or bent from the connector housing.
PATTERN B
1. Turn the ignition switch ON after replacing each part.
2. Start engine.
CAUTION:
Do not start the driving.
3. Touch CONSULT-III screen in the order of “START (NISSAN BASED VHCL)”, “TRANSMISSION”, “DATA
MONITOR”, and “MAIN SIGNALS”.
4. Warm up the transaxle assembly until “ATFTEMPCOUNT” indicates 47 [approximately 20°C (68°F)] or
more. Turn the ignition switch OFF.
5. Turn the ignition switch ON.
CAUTION:
Do not start engine.
6. Select “SELF-DIAG RESULTS”.
7. Shift the selector lever to “R” position.
8. Depress slightly the accelerator pedal (Pedal angle: 2/8) while depressing the brake pedal.
9. Perform “ERASE”.
