The scheme of fastening of a plait of an electrical wiring of the sensor on a body element

1 — To the socket of the forward wheel sensor

2 — the Basic arm

REMOVAL

 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery.
2. Disconnect an electrical wiring from the forward wheel sensor located close a casing of a support of a forward rack in a motive compartment of the car.

3. Turn out bolts of basic arms of fastening of an electrical wiring of the sensor to a suspension bracket rack.

4. Turn out bolts of an arm of fastening of a plait of an electrical wiring of the sensor to a body element.

5. Turn out a fixing bolt and remove the wheel sensor from assembly of a rotary fist.

CHECK

 PERFORMANCE ORDER

See also Section Problem Diagnostics of ABS.

1. Check a polar tip of the sensor for existence of damages and the stuck foreign particles. In case of need clear or replace the sensor.

2. Measure resistance between plugs No. No. 1 and 2 of the contact socket of the sensor. If the result of measurement exceeds the limit of admissible range (1.25 ± 0.25 kOhm), replace the sensor.

3. Check conductivity of an electrical wiring of the sensor, in case of need replace a plait.

4. Measure distance "And" between a surface and a polar tip of the sensor.

5. Measure distance "In" between the surface of a rotary fist interfaced to the sensor and a rotor of ABS.


6. = In - And determine the size of a working gap (S) between a surface of a polar tip of the wheel sensor and teeths of a rotor by a formula S. If the result of calculation exceeds the limit of the admissible range (0.3 ÷ 0.8 mm), make selection of new adjusting laying (detail No. 26755AA000).

 

7. Check the output tension of the sensor by installation of the resistor and the condenser and rotation of a wheel with a frequency, the corresponding speed of the movement of 2.75 km/h.
8. Adjustment is made by selection of adjusting laying (detail No. 26755AA000).

INSTALLATION

 PERFORMANCE ORDER

1. Temporarily fix the wheel sensor on a rotary fist. Try not to strike the sensor about metal components of a body and a suspension bracket, - especially protect a polar tip.
2. Fix a sensor electrical wiring plait in basic arms on a rack of a suspension bracket and a mudguard of a wing in a wheel arch, - bolts of fastening of basic arms are tightened with effort of 32 Nanometers.
3. By means of the probe of lezviyny type measure gap size between a polar tip of the sensor and a gear edge of a rotor (on all perimeter of the last). If the result of measurement exceeds the limit of the admissible range (0.3 ÷ 0.8 mm), achieve the demanded result by selection of the corresponding adjusting laying (detail No. 26755AA000), then tighten a boat of fastening of the sensor with the demanded effort (32 Nanometers).
4. On marking on isolation make sure of correctness of its laying, - address to the data given below.

Color marking of an electrical wiring of wheel sensors
Model Left sensor Right sensor
Legacy The yellow The white
Outback The brown The blue

5. Having made sure of correctness of a gap, connect an electrical wiring to the sensor.
6. Connect a negative wire to the battery.
