Removal

Fig. 6.71. Bolt of fastening of the sensor


Turn off a bolt of fastening of the sensor of frequency of rotation of a wheel (fig. 6.71).

Fig. 6.72. Socket of the sensor of frequency of rotation of a wheel


Disconnect the socket of the sensor of frequency of rotation of a wheel and remove the sensor (fig. 6.72).

Removal of the sensor of frequency of rotation of a back wheel
Remove a pillow of a back seat.

Fig. 6.73. Laid on panel of a back rack


Remove the laid on panel of a back rack (fig. 6.73).
Remove a wheel.

Fig. 6.74. Removal of the sensor


Disconnect the socket and remove the sensor (fig. 6.74).

Check

Fig. 6.75. Measurement of resistance between sensor conclusions


Measure resistance between conclusions of the sensor (fig. 6.75).
Nominal resistance:
– the sensor of frequency of rotation of a forward wheel – 1275–1495 Ohms.
– the sensor of frequency of rotation of a back wheel – 1275–1495 Ohms.

Fig. 6.76. Measurement of resistance between sensor conclusions at rotation of a wheel


At rotation of a wheel measure tension between conclusions of the sensor (fig. 6.76).
Nominal rate: tension of alternating current is registered.

NOTE
Install the voltmeter switch on voltage measurement of alternating current (AC voltage).
