check engine NISSAN TERRANO 2004 Service Repair Manual

Purpose
The Anti-lock Brake System (ABS) with an integrated Electronic Brake force Distribution (EBD) system con-
sists of electronic and hydraulic components. It allows you to control the braking force so that wheel lock can
be avoided during braking.
The advantages of ABS with EBD
1) Better tracking performance through improved steering wheel control.
2) Improved maneuverability and safer vehicle control.
3) Improved vehicle stability by preventing flat spins.
4) Shorter stopping distance and optimal utilisation of the rear brakes under many different circumstances.
Operation
IABS with EBD has self-test capabilities. The ABS warning lamp is illuminated for 1 second each time the
ignition switch is turned ªONº. After the engine is started, the ABS warning lamp turns off. An ABS self-test
is performed the first time the vehicle reaches 6 km/h (4 MPH) to ensure the system is operational. A
mechanical noise may be heard as the ABS performs this self-test and is a normal part of the self-test
feature. If a malfunction is detected during this check, the ABS warning lamp will stay on.
During the self-test, it also performs a EBD check when it detects a failure the ABS warning light will go
on simultaneously with the brake warning light and an audible sound will sound constantly.
I EBD system will only operate when the ABS is not in active status and it uses the inlet valves of ABS con-
trol unit to limit the pressure to the rear wheels when they tend to go into slip.
I When the vehicle speed is less than 10 km/h (6 MPH) the ABS system does not operate.
I While driving, a mechanical noise may be heard during ABS operation, this is a normal system condition.

2) Drive vehicle over 30 km/h (19 MPH) for at least one minute.
1) Stop vehicle with engine runningand touch ªSTARTº on CON-
SULT-II screen.
2) Touch ªABSº.
3) Touch ªSELF-DIAG RESULTSº.
I The screen shows the detected malfunc-
tion and how many times the ignition
switch has been turned since the mal-
function.

diagnostic procedures.
After the malfunctions are repaired, erase
the self-diagnostic results stored in the
control unit by touching ªERASEº.
Check warning lamp(s) for deactivation
after driving vehicle over 30 km/h (19
MPH) for at least one minute.

Checking Steering Wheel Play
1. With wheels in a straight-ahead position, check steering wheelplay.Steering wheel play: 35 mm (1.38 in) or less
2. If it is not within specification, check steering gear assembly when front suspension and axle, steering gear assembly and
steering column are mounted correctly.
Checking Neutral Position on Steering Wheel
CHECKING
1. Check that the steering wheel is in the neutral position whendriving straight ahead.
2. If it is not in the neutral position, remove the steering wheel and reinstall it correctly.
3. If the neutral position is between two serrated teeth, loosen tie-rod lock nut and move tie-rod in the opposite direction by the
same amount on both left and right sides to compensate for
error in the neutral position.
Front Wheel Turning Angle
Rotate steering wheel all the way right and left; measure turning
angle. Turning angle of full turns:Refer to section FA for SDS.
Checking and Adjusting Drive Belts
Refer to section MA for Drive Belt Inspection.
Checking Fluid Level
Check the fluid level in the reservoir when the engine is cold. If the
fluid level is below the MIN line, and fluid up to the MAX line.
CAUTION:
IDo not overfill the MAX level.
I Do not reuse any used power steering fluid.
I Use only ªDEXRON
TMº or equivalent.

Checking Fluid Leakage
Check the lines for improper attachment and for leaks, cracks,
damage, loose connections, chafing or deterioration.
1. Run engine between idle speed and 1,000 rpm.
Make sure temperature of fluid in oil tank rises to 50 to 80ÉC
(122 to 176ÉF).
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each ªlockº position for five seconds andcarefully check for fluid leakage.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 10 seconds (There is possibility that oil pump may be
damaged.).
4. If fluid leakage at connectors is noticed, loosen flare nut and then retighten.
Do not overtighten connector as this can damage O-ring,
washer and connector.
5. If fluid leakage at the connectors are noticed, then loosen the flare nut and retighten it.
Bleeding Hydraulic System
1. Raise front end of vehicle until wheels are clear of the ground.
2. Add fluid into oil tank to specified level. Meanwhile quickly turnsteering wheel fully to right and left and lightly touch steering
stoppers.
Repeat steering wheel operation until fluid level no longer
decreases.
3. Start engine. Repeat step 2 above.
I Incomplete air bleeding will cause the following to occur. When
this happens, bleed air again.
a. Generation of air bubbles in reservoir tank
b. Generation of clicking noise in oil pump
c. Excessive buzzing in oil pump
While the vehicle is stationary or while moving the steering wheel
slowly, fluid noise may occur in the valve or oil pump. This noise is
inherent in this steering system, and it will not affect performance
or durability of the system.

Checking Steering Wheel Turning Force
1. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating tempera-ture.Temperature: 50É - 80ÉC (122 - 176ÉF)
Tires need to be inflated to normal pressure.
4. Check steering wheel turning force when steering wheel has been turned 360É from neutral position.Steering wheel turning force: 39 N (4 kg, 9 lb) or less
I If steering wheel turning force is not within specification,
perform the following inspection procedure:

Checking Hydraulic System
Before starting, check belt tension, driving pulley and tire pressure.
1. Set Tool. Open shut-off valve, then bleed air. (Refer to ªBleed-ing Hydraulic Systemº, ST-5.)
2. Run engine.
Make sure temperature of fluid in tank rises to 60 to 80ÉC (140
to 176ÉF).
WARNING:
Warm up engine with shut-off valve fully opened. If engine is
started with shut-off valve closed, oil pressure in oil pump will
increase to relief pressure, resulting in an abnormal rise in oil
temperature.
3. Check pressure with steering wheel fully turned to left and right positions with engine idling at 1,000 rpm.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 15 seconds. Oil pump maximum standard pressure:TD27Ti engine8,800 - 9,200 kPa (88 - 92 bar,
89 - 93 kg/cm
2, 1,276 - 1,334 psi)
ZD30DTi engine 9,800 - 10,500 kPa (98.0 - 105.0 bar,
99.96 - 107.10 kg/cm
2, 1,421 - 1,523 psi)
4. If oil pressure is below the maximum pressure, slowly close shut-off valve and check pressure.
I When pressure reaches maximum pressure, gear is damaged.
I When pressure remains below maximum pressure, pump is
damaged.
CAUTION:
Do not close shut-off valve for more than 15 seconds.
5. If oil pressure is higher than maximum pressure, check oil pump flow control valve.
6. After checking hydraulic system, remove Tool and add fluid if necessary, then completely bleed air out of system.NST033
