SELF-DIAGNOSIS
Description
If an error is detected in the system, the ABS warning lamp will turn on. In this case, perform self-diagnosis as
follows:
Operation Procedure
1. Turn ignition switch OFF.
2. Connect CONSULT-III to the data link connector.
3. Turn ignition switch ON.
4. Start engine and drive at approximately 30 km/h (19 MPH) or more for approximately 1 minute.
5. After stopping the vehicle, with the engine running, touch “ABS”, “SELF-DIAG RESULTS” in order on the
CONSULT-III screen.
6. The self-diagnostic results are displayed. (If necessary, the self-diagnostic results can be printed out by
touching “PRINT”.)
• When “NO DTC IS DETECTED” is displayed, check the ABS warning lamp.
7. Conduct the appropriate inspection from the display item list, and repair or replace the malfunctioning
component.
8. Start engine and drive at approximately 30 km/h (19 MPH) or more for approximately 1 minute.
CAUTION:
• When a wheel sensor “short-circuit” is detected, if the vehicle is not driven at 30 km/h (19 MPH)
for at least 1 minute, the ABS warning lamp will not turn off even if the malfunction is repaired.
9. Turn ignition switch OFF to prepare for erasing the memory.
10. Start the engine and touch “ABS”, “SELF-DIAG RESULTS”, “ERASE” in order on the CONSULT-III screen
to erase the error memory.
If “ABS” is not indicated, go to GI-36, "
CONSULT-III Data Link Connector (DLC) Circuit".
CAUTION:
If the error memory is not erased, re-conduct the operation from step 5.
11. For the final inspection, drive at approximately 30 km/h (19 MPH) or more for approximately 1 minute and
confirm that the ABS warning lamp is off.

TROUBLE DIAGNOSES FOR SYMPTOMS
2. Drive vehicle and check brake operation.
NOTE:
• Stopping distance may be longer than vehicles without ABS when road condition is slippery.
• Driving the vehicle with the ABS actuator and electric unit (control unit) disconnected may induce DTCs
in electrical control units using CAN communication. After the inspection, clear all DTCs. Refer to LAN-
6, "System Description".
OK or NG
OK >> GO TO 4.
NG >> Perform Basic Inspection. Refer to BRC-16, "
Basic Inspection".
4.CHECK WHEEL SENSORS
Check the following.
• Wheel sensor mounting for looseness
• Wheel sensors for physical damage
• Wheel sensor connectors for terminal damage or loose connections
• Sensor rotor and mount for physical damage
OK or NG
OK >> Check ABS actuator and electric unit (control unit) connector terminals for deformation, discon-
nection, looseness or damage. Reconnect ABS actuator and electric unit (control unit) harness
connector. Then retest.
NG >> Repair or replace as necessary.
Long Stopping DistanceINFOID:0000000001703847
1.CHECK BASE BRAKING SYSTEM PERFORMANCE
1. Disable ABS by disconnecting ABS actuator and electric unit (control unit) connector.
2. Drive vehicle and check brake operation.
NOTE:
• Stopping distance may be longer than vehicles without ABS when road condition is slippery.
• Driving the vehicle with the ABS actuator and electric unit (control unit) disconnected may induce DTCs
in electrical control units using CAN communication. After the inspection, clear all DTCs. Refer to LAN-
6, "System Description".
OK or NG
OK >> Go to BRC-29, "ABS Works Frequently".
NG >> Perform Basic Inspection. Refer to BRC-16, "
Basic Inspection".
ABS Does Not WorkINFOID:0000000001703848
CAUTION:
The ABS does not operate when the vehicle speed is 10 km/h (6 MPH) or less.
1.CHECK WARNING LAMP ACTIVATION
Turn ignition switch ON and check for warning lamp activation.
• Warning lamp should activate for approximately 2 seconds after turning the ignition switch ON.
OK or NG
OK >> Carry out self-diagnosis. Refer to BRC-18, "CONSULT-III Function (ABS)".
NG >> Go to BRC-16, "
Basic Inspection".
Pedal Vibration or ABS Operation NoiseINFOID:0000000001703849
NOTE:
During ABS activation, pedal vibration may be felt and a noise may be heard. This is normal and does not indi-
cate a malfunction.
1.CHECK SYMPTOM
1. Apply brake.
2. Start engine.
Does the symptom occur only when engine is started?
YES >> Carry out self-diagnosis. Refer to BRC-18, "CONSULT-III Function (ABS)".

1. Install reservoir tank if removed. Refer to CO-11.
2. Install radiator drain plug.
•If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-76
.
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring. Refer to CO-11, "
Component".
3. Make sure that each hose clamp has been firmly tightened.
4. Remove air duct assembly. Refer to EM-16
.
5. Disconnect heater hose (1) at position ( ) as shown.
• Front
• Reposition heater hose as high as possible.
6. Fill radiator and reservoir tank to specified level.
•Pour engine coolant through engine coolant filler neck
slowly of less than 2 (2 1/8 US qt, 1-3/4 lmp qt) a minute
to allow air in system to escape.
•Use NISSAN Genuine Engine Coolant or equivalent mixed
with water (distilled or demineralized). Fill cooling system
to specification. Refer to MA-10
.
• When engine coolant overflows disconnected heater hose,
connect heater hose, and continue filling the engine coolant, if
heater hose is disconnected.
7. Install radiator cap.
8. Install air duct assembly. Refer to EM-16
.
9. Warm up until opening thermostat. Standard for warming-up time is approximately 10 minutes at 3,000
rpm.
• Make sure thermostat opening condition by touching radiator hose (lower) to see a flow of warm water.
CAUTION:
Watch water temperature gauge so as not to overheat the engine.
10. Stop engine and cool down to less than approximately 50°C (122°F).
• Cool down using fan to reduce the time.
• If necessary, refill radiator up to filler neck with engine coolant.
11. Refill reservoir tank to “MAX” level line with engine coolant.
12. Repeat steps 6 through 11 two or more times with radiator cap installed until engine coolant level no
longer drops.
13. Check cooling system for leaks with engine running.
14. Warm up engine, and check for sound of engine coolant flow while running engine from idle up to 3,000
rpm with heater temperature controller set at several position between “COOL” and “WARM”.
• Sound may be noticeable at heater unit.
15. Repeat step 14 three times.
16. If sound is heard, bleed air from cooling system by repeating steps 6 through 11 until engine coolant level
no longer drops.
FLUSHING COOLING SYSTEM
1. Install reservoir tank if removed. Refer to CO-11.
2. Install radiator drain plug.
•If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-76
