REAR WHEEL SPEED SENSOR OUTPUT VOLTAGE INSPECTION
Check in the same procedure as that used of front wheel speed sensor check.
Output AC voltage at 2/3 to one rotation per second (25 - 38 Hz): 100 mV or more
Reference
When using oscilloscope, peak-to-peak voltage at 2/3 to one rotation per second (25 - 38 Hz): 150 mV or more
