Front Wheel Speed Sensor Removal And Installation - Suzuki GRAND VITARA JB416 Service Manual

4E-37 ABS:
7) Measure voltage at resistance with wheel rotation
and confirm voltage alternately changes between
high and low voltages.
If voltage does not change with wheel rotation, check
sensor, mating encoder and their installation
conditions.
Voltage at the resistance (115 Ω) with wheel
rotation
High voltage "a": 1360 to 1930 mV
Low voltage "b": 680 to 960 mV
[A]: Voltage
Reference
When using oscilloscope for this check, check if peak-to-
peak voltage and waveform meet specification.
Peak-to-peak Voltage at the resistance (115 Ω) with
wheel rotation
High voltage "a": 1360 to 1930 mV
Low voltage "b": 680 to 960 mV

Front Wheel Speed Sensor Removal and
Installation
Removal
1) Disconnect negative (–) cable from battery.
2) Disconnect front wheel speed sensor coupler (1).
3) Hoist vehicle and remove wheel.
4) Remove harness clamp, clamp bolts (2) and
grommet (3).
5) Remove front wheel speed sensor (4) from knuckle.
CAUTION
!
• Do not pull wire harness when removing
front wheel speed sensor.
• Do not cause damage to surface of front
wheel speed sensor and do not allow dust,
etc. to enter its installation hole.

Installation
1) Check that no foreign material is attached to sensor
(1) and mating encoder (2).
2) Install it by reversing removal procedure.
Tightening torque
Front wheel speed sensor bolt (a): 11 N·m (1.1
kgf-m, 8.0 lb-ft)
Front wheel speed sensor harness clamp bolt
(b): 11 N·m (1.1 kgf-m, 8.0 lb-ft)
CAUTION
!
Do not pull or twist wire harness more than
necessary when installing front wheel speed
sensor.
