4. Start the engine and bring the engine speed up to
full throttle.
5. Move the traction control in the left direction, in

the system oil temperature to rise.

Note: Raising the system oil temperature will
make a difference in the readings you
receive. To complete the test accurately,

operating temperatures. Suggested
temperature range 160° - 210° F (71.1° -
98.9° C).
