Eps Unit Current Test - TGB BLADE 600 Service Manual

EPS Unit Current Test

1. Connect vehicle to the latest BUS software.
2. Click on the Rear Data button.
3. Choose the Monitoring page tab.
4. At the bottom of the Monitoring page, choose
the EPS tab.
5. With the vehicle engine running in N, turn the
handlebar side to side, momentarily against
each stop and observe the indications on the
BUS EPS Monitoring page.
▪ The EPS Torque Sensor Nm increase with
torque applied to the handlebar.
▪ The EPS Current ammeter should increase
proportionately to the torque applied and
decrease with the torque as steering assist is
provided.
NOTE: Increase and decrease in torque and
current 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 NM with a corresponding
current draw is acceptable.
▪ If current draw tends to remain high, carry out
the following:
- Steering alignment check.
- Steering column shim adjustment at half
bushings as described in the EPS UNIT
INSTALLATION procedure detailed in this
section.
- TORQUE OFFSET RESET procedure detailed
in this section.
- Replace EPS unit.
