5. With the vehicle engine running in PARK, turn
the handlebar side to side, momentarily against
each stop and observe the indications on the
B.U.D.S. DPS Monitoring page.
The DPS Torque Sensor Nm increase with torque
applied to handlebar.
The DPS Current ammeter should increase pro-
portionately to the torque applied, and decrease
with the torque as steering assist is provided.

TYPICAL - LH TURN
1. Torque sensor indication (negative)
2. DPS current indication (positive)

TYPICAL - RH TURN
1. Torque sensor indication (positive)
2. DPS current indication (negative)
NOTE: Increase and decrease in torque and cur-
rent readings is very brief as steering assist is
quickly provided. Current draw should remain
within green scale but may momentarily peak to
60 amps, then drop off close to 0 amps as torque
applied is nulled out by steering assist. A residual
torque of 2 N•m (18 lbf•in) with a corresponding
current draw is acceptable.
If current draw tends to remain high, carry out the
following:
– Steering alignment check.
