Peorm a function check by closing the driver side front door and opening it again. The front bracket assembly (A)
motor should activate the linkage arm and move it into the down or “deployed” position.
After deploying linkage arms, unplug the motor connector from the LED-Y harness (to cut power to the linkage
arms), while front door is open, to hold deployed position for running board installation.
Line up the carriage bolts (E), under the power step boards, with the slots on the linkage arms (A & B). Inse the
8 carriage bolts (E) into the slots on front and rear linkage arms. Adjust board to desired position. Moderately
hand tighten the 6mm Flat Washers + 6mm Nylon Lock Nuts (G) onto the carriage bolts.
Once the board is adjusted, plug in motor connector to the LED-Y harness (to return power to the linkage arms),
making sure that the door remains open. Proceed to open and close doors several times to deploy and retract the
steps to settle the steps into their natural alignment. After cycling the step, tighten all hardware on the board and
brackets.
Some fuher adjustment may be required for desired step position. Repeat for passenger side.
15
Peorm system check and troubleshooting. If board is making irregular movements or noise, readjust the boards
as follows:
a. With board deployed loosen 6mm nuts under board.
b. Leave the nuts slightly less than snug.
c. Open and close door several times for board to settle into position.
d. With the step in the deployed position, gradually tighten the nuts while alternating between each. Do not over
tighten.
If board is making abnormal noise or the motion is binding, repeat steps “a” through “d”.
NOTE
If the above method does not resolve the issue, the brackets mounting to the vehicle may not be aligned
properly with the vehicle. In this case, remove the board and realign brackets before attempting steps “a”
to “d” once again.

17
Reinstall any remaining trim panels if necessa. Check and make sure all hardware is fully tightened. Peorm a
nal system check. Finish.
NOTE
・
If board does not move during
troubleshooting, check the wire taps
for a solid connection or ip the
CAN Signal High and Low wires.
・
If board still does not move during
troubleshooting, it may also be
necessa to check all other wiring
connections.
