Front Wheel Speed Sensor Removal And Installation - Suzuki SX4 Service Manual

4E-35 ABS:
5) Measure voltage at resistance without wheel
rotation.If voltage is out of specification, check
sensor, mating encoder and their installation
conditions.
Voltage at the resistance (115 Ω) without wheel
rotation
680 – 960 mV
6) 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 (115Ω) with wheel
rotation
High voltage "a": 1360 – 1930 mV
Low voltage "b": 680 – 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
