Step 2
1) Connect the TO sensor coupler.
2) Insert the needle pointed probes to the lead wire coupler.
3) Turn the ignition switch ON.
4) Measure the voltage at the wire side coupler between Br/W
and B/Br wires.

Also, measure the voltage when leaning the vehicle.
5) Dismount the TO sensor from its bracket and measure the
voltage when it is leaned 65 ° and more, left and right, from
the horizontal level.
