Examination
1. Measure the resistance between the connector pins of each sensor.
- Rated resistance - 1.25 - 1.55 kOhm
If the value is out of specification, replace the sensor.
2. Check for continuity between each of the leads and the sensor housing. If there is continuity, replace the sensor.
pressure modulator.
1 - brake pipes from the master brake cylinder,
2 - brake pipes,
3 - pressure modulator connector,
4 - pressure modulator.
3. Check the correct installation of the wheel speed sensor and the compliance of the tightening torque of the sensor mounting bolt with the permissible value.
- Tightening torque - 19 Nm
4. Measure the gap between the rotor and speed sensor.
- Nominal clearance - 1.0 mm
5. Check the sensor rotor for scratches, cracks, deformation, or missing teeth.
Pressure sensors in the main brake cylinder.
1 - sensor-switch for pressure in the main brake cylinder,
2 - pressure sensor in the main brake cylinder.
