2003 NISSAN X-TRAIL relay

BRC-110
[ESP/TCS/ABS]
TROUBLE DIAGNOSIS

Actuator operation check
1. Connect 9 and 10 terminals of actuator to 40 and 41 terminals of
relay box.
2. Measure the motor voltage (No.4 terminal to body earth) with
oscilloscope. Then check the motor reverse voltage occasioned
time.
The motor reverse voltage occasioned time is more than 0.1
sec.
CAUTION:

Perform checking of motor relay unit. Then confirm that
relay functions.

Driving actuator motor is with in 4 sec. to prevent heating
up.

Standard condition of the motor reverse voltage occa-
sioned time is: Battery voltage is 12V. Temperature 20°.
when the battery voltage or temperature is lower than the
standard, the motor reverse voltage occasioned time
becomes slightly shorter.
Symptom 1: ABS Works Frequently.EFS001AS
Inspection procedure
1. INSPECTION START
Check the wheel sensor system.

Sensor mounting inspection

Sensor pick-up inspection for iron chips

Sensor rotor inspection (e.g. Number of teeth, damaged teeth)

Sensor connector engagement inspection
Is inspection result OK?
YES >> GO TO 2.
NO >> Refer to wheel sensor and rotor lines.
2. LOOSENESS INSPECTION
Check front axle for looseness.
Is inspection result OK?
YES >>BRC-110, "Symptom 2: Unexpected Pedal Action"
NO >> Axle inspection and repair
Symptom 2: Unexpected Pedal ActionEFS001AT
Inspection procedure
1. BRAKE PEDAL STROKE INSPECTION
Check the brake pedal stroke.
Is the stroke excessively long?
YES >> Check the bleeding and brake system.
NO >> GO TO 2.

2. PEDAL FORCE INSPECTION
Check that brake is effective with the pedal depressed.
Is the pedal force heavy, but effective?
YES >> Normal
NO >> GO TO 3.
3. CONNECTOR AND PERFORMANCE INSPECTION
Disconnect the actuator relay unit connector to deactivate the ABS function. Check that brake is effective.
Is brake effective?
YES >> GO TO 4.
NO >> Brake line inspection
4. ABS WARNING LAMP INDICATOR INSPECTION
Check that ABS warning lamp illuminates.
Does ABS warning lamp illuminate?
YES >> Perform the self-diagnosis.
NO >> GO TO 5.
5. WHEEL SENSOR INSPECTION
Check the wheel sensor system.

Sensor mounting inspection

Sensor pick-up inspection for iron chips

Sensor rotor inspection (e.g. Number of teeth, damaged teeth)

Sensor connector engagement inspection
Is inspection result OK?
YES >> Normal
NO >> Wheel sensor and rotor lines repair
Symptom 3: Longer Stopping DistanceEFS001AU
Inspection procedure
1. INSPECTION START
Check that the stopping distance when braking becomes longer only on a snowy or gravel road.
Does the stopping distance when braking become longer only on a snowy or gravel road?
YES >> It may be longer than that of vehicle without ABS.
NO >> GO TO 2.
2. PERFORMANCE CHECK
Disconnect the actuator relay box to deactivate the ABS function.
Is the stopping distance still longer?
YES >>
Brake line air bleeding

Brake line inspection
NO >> GO TO 3.
3. ABS WARNING LAMP INDICATOR INSPECTION
Check that ABS warning lamp illuminates.
Does ABS warning lamp illuminate?
YES >> Perform the self-diagnosis.
NO >> GO TO 4.

Removal and InstallationEFS001CR

The above figure shows LH model. RH model figure is the mirror image.

Pay attention to the following when removing actuator.
Be careful of the following.
CAUTION:

Before servicing, disconnect the battery terminals.

To remove the brake tube, use a flare nut wrench to prevent the flare nuts and brake tube from
being damaged. To install, use a brake tube torque wrench.

Do not remove and install the actuator by holding the harness.

After completing the work, bleed the brake piping of air. Refer to BR-9, "Bleeding Brake System" .

Make sure to connect the ground terminal securely.
