22.21.1.4. Sensor of a back wheel

GENERAL INFORMATION

Prevention

At installation of the sensor it is necessary to use a new bolt of fastening.


Arrangement of the sensor of a back wheel on a case of reverse main gear

PERFORMANCE ORDER
1. Lift a back part of the car and fix on supports.
2. For improvement of access to the electric socket of the sensor remove back sitting.
3. Check that ignition is switched off, then disconnect the electric socket of the sensor from a plait of wires. Release sensor electroconducting from fastening brackets in order that it could be removed together with the sensor.
4. Working under the car, take sensor electroconducting from the brackets, fixing it to the car bottom.
5. Unscrew a bolt of fastening and remove the sensor with a sealing ring from a case of reverse main gear (see drawing). Check a condition of a sealing ring of the sensor and, if necessary, replace it. At installation of the sensor it is necessary to use a new bolt of fastening.

Installation

PERFORMANCE ORDER
1. Clear interfaced surfaces of the sensor and a case of reverse main gear and establish a new sealing ring of the sensor.
2. Establish the sensor on a place and fix it a new bolt, having tightened it the demanded moment.
3. Pass the electric socket of the sensor through rubber consolidation in the car bottom, then in salon of the car connect the electric socket to the main plait of wires. Fix brackets sensor electroconducting.
4. Establish back sitting and lower the car.
