22.21.1.3. Sensor of a forward wheel

Removal

Arrangement of bolts of fastening of the sensor of a forward wheel

PERFORMANCE ORDER
1. Tighten the parking brake, then lift a forward part of the car and fix on supports. Remove the corresponding forward wheel.
2. Check that ignition is switched off, then remove the electric socket from a bracket of fastening and disconnect it from the main plait of wires. Take sensor electroconducting from brackets of fastening and clamps.
3. Unscrew a bolt, the fixing sensor to a rotary fist, and remove the sensor together with wires (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 of pollution the sensor of a wheel and grooves of a rotor of the sensor of a wheel. Put on interfaced surfaces of the sensor and a rotary fist a thin layer of greasing.
2. Establish a sealing ring of the sensor.
3. Establish the wheel sensor in a rotary fist and fix new bolts, having tightened them the demanded moment.
4. Fix to a sensor electricity cable brackets and clamps. Check that a sealing ring of the electric socket in a good condition, then connect the electric socket and fix it a bracket.
5. Establish a wheel, then lower the car on the earth and tighten bolts of fastening of a wheel the demanded moment.
