disconnect the battery and then recon-
nect it.
Measure the voltage on the speed
meter connector (white three-pin
connector) between the red/white
and black leads.
Speed sensor
1. Check:
Speed sensor output voltage and
pulses
Out of specification → Replace.
Speed sensor output voltage
(dependant on the paddle wheel
position):
Less than 400 mV/
more than 11.6 V
Output pulse:
2 pulses/one-full turn
Checking steps:
Apply DC 12 voltage to the white
three-pin connector between the red/
white and black leads.
Rotate the paddle wheel by hand and
measure the voltage between the
black and yellow leads.
NOTE:
As the paddle wheel is rotated, a square-
wave voltage signal a is produced.
Two pulses occur every time the pad-
dle wheel makes one-full turn.
