Speed Sensor Inspection - Suzuki VLR1800 Service Manual

Installation
Install the speed sensor in the reverse order of removal.
Pay attention to the following points:
• Apply grease to the O-ring.
CAUTION
!
Use a new O-ring to prevent oil leakage.
: Grease 99000–25010 (SUZUKI SUPER
GREASE A or equivalent)
• Tighten the speed sensor mounting bolt (1) to the
specified torque.
Tightening torque
Speed sensor mounting bolt (a): 10 N·m (1.0 kgf-
m, 7.0 lb-ft)
• Route the speed sensor lead wire. Refer to "Wiring
Harness Routing Diagram in Section 9A (Page 9A-7)".

1) Remove the speed sensor. Refer to "Speed Sensor
Removal and Installation (Page 9C-6)".
2) Connect a 12 V battery (between B and B/W), 10 kΩ
resistor (between B/R and B) and multi-circuit tester
(tester (+) probe to B and tester (–) probe to B/R) as
shown in the figure.

3) Move a screwdriver back and forth across the pick-
up surface of the speed sensor. The voltage
readings should cycle as follows (0 V → 12 V or 12 V
→ 0 V). If the voltage reading does not change,
replace the speed sensor with a new one.
NOTE
While testing, the highest voltage reading
should be the same as the battery voltage (12
V).
