1) Turn the ignition switch OFF.
2) Connect the torque sensor coupler.
3) Insert the needle pointed probes to lead wire coupler.
4) Measure the torque sensor (main) voltage between G
wire “A” and B wire “B”. Also, measure the torque sensor
(sub) voltage between W wire “C” and B wire “B” by full
turning the handlebars left and right.
Special tool
(A): 09900–25008 (Multi-circuit tester set)
(B): 09900–25009 (Needle pointed probe set)
Tester knob indication
Voltage (
)
Torque sensor (main/sub) voltage
Handlebars left turn (Main): Approx. 3.0 V
Handlebars left turn (Sub): Approx. 2.0 V
Handlebars right turn (Main): Approx. 2.0 V
Handlebars right turn (Sub): Approx. 3.0 V
Is voltage OK?
• G, W and B wire open
or shorted to ground
or poor torque sensor
coupler connection.
• If wire and
connection are OK,
intermittent trouble or
faulty EPS control
unit.
• Replace the EPS
control unit with a
known good one, and
inspect it again. Refer
to “EPS Control Unit
Removal and
Installation (Page 6C-
48)”.
If check result is not
satisfactory, replace the
torque sensor (EPS
body assembly) with a
new one. Refer to “EPS
Body Assembly
Removal and
Installation (Page 6C-
49)”.
