GRAND
VITARA
5E1-34 ANTILOCK BRAKE SYSTEM (ABS) (OPTIONAL)
1. Left front wheel speed sensor
2. Left front strut
3. Sensor rotor
1. Wheel speed sensor connector
1. Peak-to-peak voltage
FRONT WHEEL SPEED SENSOR
OUTPUT VOLTAGE INSPECTION
1) Turn ignition switch OFF.
2) Hoist vehicle a little.
3) Disconnect connector of wheel speed sensor.
4) Connect voltmeter between connector terminals.
5) While turning wheel at a speed of approximately 2/3 to 1 full
rotation per second, check AC voltage of sensor.
Output AC voltage at 2/3 to
one rotation per second (35 – 53 Hz): 106 mV or more
If measured voltage is not as specified, check sensor, rotor and
their installation conditions.
Reference
When using oscilloscope for this check, check if peak-to-peak volt-
age meets specification and waveform is complete.
Peak-to-peak voltage
at 2/3 to one rotation per second (35 – 53 Hz): 150 mV or more
