11:17. Removal, check installation of wheel ABS sensors
Sensors of forward wheels
Removal
|
|
- Disunite the contact socket of an electrical wiring of the sensor.
|
|
- Turn out a fixing bolt and remove the sensor.
|
|
|
Check
|
|
- Hang out the car above the ground and attentively study a condition of rotors of wheel sensors from the back party of forward naves, - in case of identification of the damaged teeths the rotor is subject to replacement (see the Section Replacement of Rotors of ABS Sensors of Forward Wheels).
|
|
- Measure a gap between a sensitive element of the sensor and teeths of its rotor, - the required value makes 0.3 ÷ 1.0 mm.
|
- Measure sensor resistance, - the result of measurement should not exceed the limit of the range of 1385 ± 110 Ohms.
|
|
Installation
|
|
- Installation is made upside-down, - previously carefully smooth out the landing surface of the sensor. The required value of effort of tightening of a fixing bolt makes 9.5 Nanometers.
|
|
Sensor of back wheels
Removal
|
|
The back sensor is fixed on a case of a reducer of the back bridge and traces turns of the conducted gear wheel of the main transfer, - the rotor of the sensor is fixed on a box of interwheel differential. |
Check
|
|
|
|
- Estimate a condition of a sealing ring (1) of the sensor, - in case of need make replacement.
|
|
|
- Measure distance (A) between the landing surface of the sensor (1) and teeths of its rotor (2).
|
- Measure length of a sensitive element of the sensor (B).
- By subtraction of result of the second measurement from result of the first (And – In) determine the size of a working gap, - the required value lies within the range of 0.5 ÷ 1.0 mm.
- If the result of calculation makes less than 0.55 mm, pick up the corresponding thickness an adjusting washer.
- At the excessive size of a gap the sensor should be replaced.
- Measure sensor resistance, - the result of measurement should not exceed the limit of the range of 1000 ± 50 Ohms.
