BRAKE FLUIDPFP:KN100
On-Board Inspection NFS000OU
CHECKING BRAKE FLUID LEVEL
Make sure that a brake fluid level in reservoir tank is within the
standard (between MAX and MIN lines).
Visually check around reservoir tank for fluid leakage.
If the level is excessively low, check brake system for leakage.
Release parking brake pedal and see if brake warning lamp
goes off. If not, check brake system for fluid leakage.
Checking Brake LineNFS000OV
CAUTION:
If leakage occurs around joints, retighten or, if necessary, replace damaged parts.
1. Check brake line (tubes and hoses) for cracks, deterioration or other damage. Replace any damaged
parts.
2. Check for oil leakage by fully depressing brake pedal while
engine is running.
Drain and RefillNFS000OW
CAUTION:
Refill with new brake fluid “DOT 3”.
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.
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 brake pedal, loosen bleed valve, and gradually remove
brake fluid.

Self-DiagnosisNFS000QG
OPERATION PROCEDURE
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data link connector.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which performs CAN communication.
3. Turn ignition switch ON.
4. Start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute.
5. After stopping vehicle, with the engine running, touch “START (NISSAN BASED VHCL)”, “ABS”, “SELF-
DIAG RESULTS” in order on the CONSULT-II screen.
CAUTION:
If “START (NISSAN BASED VHCL)” is touched immediately after starting engine or turning on the
ignition switch, “ABS” might not be displayed in the “SELECT SYSTEM” screen. In this case,
repeat the operation from step 1.
6. The self-diagnostic results are displayed. (Touch “PRINT” to print out self-diagnostic results, if necessary.)
Check ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp if “NO FAILURE” is dis-
played. Refer to BRC-53, "
Inspection 19: Warning Lamp and Indicator Lamp Circuit" .
7. Perform the appropriate inspection from display item list, and repair or replace the malfunctioning compo-
nent.Refer to BRC-24, "
DISPLAY ITEM LIST" .
8. Start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute.
CAUTION:
When the wheel sensor malfunctions, after inspecting the wheel sensor system, the ABS warning
lamp, VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp will not turn off even
when the system is normal unless the vehicle is driving at approximately 30 km/h (19 MPH) or
more for approximately 1 minute.
ERASE MEMORY
1. Turn ignition switch OFF.
2. Start engine and touch “START (NISSAN BASED VHCL)”, “ABS”, “SELF-DIAG RESULTS”, “ERASE
MEMORY” in order on the CONSULT-II screen to erase the diagnostic memory.
If “ABS” is not indicated, go to GI-40, "
CONSULT-II Data Link Connector (DLC) Circuit" .
CAUTION:
If the diagnostic memory is not erased, re-perform the operation from step 4.
3. Perform self-diagnosis again, and make sure that diagnostic memory is erased.
4. Drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute as the final inspection, and make
sure that the ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp
turn off.
NOTE:
Brake warning lamp will turn on in case of parking brake operation (when switch is ON) or of brake fluid
level switch operation (when brake fluid is insufficient).
VDC OFF switch should not stay "ON" position.

Basic InspectionNFS000QK
BASIC INSPECTION 1: BRAKE FLUID LEVEL, LEAK INSPECTION AND BRAKE PAD
1. Check fluid level in brake reservoir tank. If fluid level is low, refill brake fluid. Refer to BR-10, "CHECKING
BRAKE FLUID LEVEL" .
2. Check for leakage in brake tubes or hoses and around ABS actuator and electric unit (control unit). If
there is leaking or seeping fluid, check the following items.
If the brake tube connections at ABS actuator and electric unit (control unit) are loose, tighten flare nuts
to the specified torque. Then inspect again and confirm that there is no leakage.
If flare nuts or screws of ABS actuator and electric unit (control unit) are damaged and loose, replace
damaged parts. Then inspect again and confirm that there is no leakage.
If there is leakage at any location other than ABS actuator and electric unit (control unit) connections,
wipe away leakage with clean cloth. Then inspect again and confirm that there is no leakage.
If there is leakage from ABS actuator and electric unit (control unit), wipe away leakage with clean cloth.
Then inspect again. If there is still leakage, replace ABS actuator and electric unit (control unit).
CAUTION:
ABS actuator and electric unit (control unit) cannot be disassembled.
3. Check brake disc rotor and pads. Refer to BR-28, "
DISC ROTOR INSPECTION" (front disc rotor), BR-23,
"PAD WEAR INSPECTION" (front brake pad), BR-34, "DISC ROTOR INSPECTION" (rear disc rotor), BR-
29, "PAD WEAR INSPECTION" (rear brake pad).
BASIC INSPECTION 2: LOOSENESS OF POWER SYSTEM TERMINALS AND BATTERY
Check battery for looseness on battery positive/negative terminals and ground connection. Also make sure
battery voltage does not drop and alternator is normal.
