The motor must be put on in step 15 after the linkage is tightened to the body of the vehicle.
To ensure our customers receive all components with full integrity, we pack the motors separate from their Linkage assemblies. This requires that the installer position and fasten the motor before continuing with the install. Please follow the instructions below and handle the assembly carefully.
CAUTION: Dropping the assembly or any excessive impact MAY cause damage to the motor.

1. Position the gear cover in place as shown if not already in place.
2. Seat motor into position on the three mounting bosses. This may require an adjustment of the gear by moving the swing arms.
3. After seating into place, fasten the motor with the three motor mount screws with 4mm Hex Head. Tighten screws to 36 in-lbs (4N-m). Do not over torque.

Check that all doors activate the PowerStep and the LED lights work when doors open and close.
NORMAL OPERATION : When the doors open, PowerStep automatically deploys from under the vehicle.
When the doors are closed, PowerStep will automatically return to the stowed/retracted position. Note that there is a 2-second delay before the PowerStep returns to the stowed/retracted position.
CORRECT OPERATION OF LIGHTS: All four lamps will illuminate upon opening any door of vehicle. Lamps will stay on until restowing of both Power Steps or until 5 minutes has expired with the doors open. When the lights timeout after 5 minutes, they can be reillumintated by closing and opening any door of vehicle.
Congratulations on your purchase of the genuine AMP Research PowerStep!
Here’s what you should know…
POWER-DEPLOYABLE RUNNING BOARDS OPERATION: AMP Research PowerStep running boards automatically move when the doors are opened to assist entering and exiting the vehicle.
Automatic power deploy: The running boards will extend down and out when the doors are opened.
Automatic power stow: The running boards will return to the stowed position when the doors are closed. There will be a 2-second
delay before the running boards move to the stowed position.
Automatic stop:
If an object is in the way of the moving running board, the running board will automatically stop.
To reset, clear any obstruction, then simply open and close the door to resume normal operation.
Manually set in the deployed (OUT) position for access to the roof:The running boards can be manually set in the deployed position by firmly holding the step down with your foot while at the same time closing the door. To resume normal operation, open and close the door.
Maintenance: In adverse conditions, debris such as mud, dirt, and salt may become trapped in the running board mechanism, possibly leading to unwanted noise. If this occurs, manually set the running boards to the deployed position and flush the front and rear hinge arms with a high-pressure car wash wand. Avoid spraying the motors directly. After washing, apply silicone spray lubricant to the hinge pivot pins.
Do not apply silicone, wax or protectants like Armor All® to the running board stepping surface.
Caution! Keep hands away when the running board is in motion.
