Maintenance
How to clean your steps
Cleaning your PowerStep
In adverse conditions, debris such as mud, dirt, and salt may become trapped in the running board mechanism, possibly leading to unwanted noise, or binding.
Prepare for cleaning
Manually set the running boards to deploy:
The running boards can me manually set in the deployed position by opening the door, and then place your foot on the step. Leave firm pressure with your foot on the step while you close the door. This will leave your steps in the deployed position.
How to maintain your steps:
Using a pressure washer to clean the front and rear linkages which are all 4 hinge points for your PowerSteps. Avoid spraying the motors directly.
After washing, apply silicone spray (dry Film lubricant) only, to all 4 linkage arms and all pivot pins, some of these pins will be located up high on the linkage arm as well. Then cycle the door to work the lubrication in to the hinge points.
Do not apply silicone, wax, or protectants like Armor All® to the running board. Do not lubricate with any greases, oils, WD-40, or penetrants.
This cleaning should be done periodically, or when debris such as mud, dirt or salt becomes trapped in the running board mechanism.

Deployment of PowerSteps
Step is clicking when deploying or retracting
Bolt & Wedge Adjustment
Remove motor from side that is being effected.
Allow step to rest in the fully deployed or down position.
Unscrew ¼ -20x7/8 socket head or gold colored hex cap screw located at the top of the linkage arm in the rear.
Loosen 3-4 turns and strike the head of the bolt with a hammer lightly to push wedge loose from the linkage arm. (note: threaded hole on wedge is not in the center of the wedge.)
Apply light pressure to the running board and reinstall wedge and bolt.
Torque bolt to 12ft lbs.
Re install motor and retest.

My LED lights will not shut off or are not turning on.
Testing LED light voltage
Start by closing all doors on the vehicle
Locate the small 8 pin plug located at your controller. (pic attached labeled override pinning can be used)
Using a DMM (digital multimeter) insert the red lead of your meter into the back of the controller at the red wire.
Insert your black lead into the back of the controller at the black wire.
Set to Volts DC on your meter.
When you open any door your meter should display 12v + or battery voltage and when the door is closed the voltage should go away.
If you are not seeing the voltage effected by the operation of the door proceed to the next step.
Unplug small 8 pin plug from the controller.
Using your multimeter, meter out the pins directly in the controller and run the same test as previous.
If you are seeing that voltage is staying constant no matter if you open or close any door you may be experiencing an issue with the controller.
If you are receiving voltage when you open the door and it goes away when you close the door you may be experiencing an issue in the harness or with your LED lights.

Disconnected the vehicles battery and my steps no longer deploy or retract.
If you are experiencing this issue, you may have a component in the system that received a spike in voltage. If you believe you may be experiencing this issue, follow the steps below:
Controller Reset:
Locate Amp Research Controller under the hood. The controller will have a red wire going from the red + terminal of the battery directly to the controller.
Locate fuse holder on red wire going to the controller.
Remove the 30/40-amp fuse to the system.
Verify both locking clips are fully locked into the controller.
Push each one of the wires individually deep into the controller.
Let the system sit for 5 minutes.
Reinstall the fuse into the controller and retest.
If your issue is not resolved proceed to the next step.
Controller vs. OBDII Failure:
Complete controller reset procedure before performing this test.
Locate OBDII module plug under dash. This will be plugged in to the vehicles diagnostic port and look like the image below:
Follow black pigtail off side of plug till it splits in to 2 purple wires. (Note: One is purple, and one is purple/black stripe)
Disconnect purple and purple/black stripe wires from splice point under dash.
Put OBDII plug to the side it will not be used.
Locate a solid chassis ground location in the vehicle. (Note: Chassis ground locations can be found on any non-painted bare metal location in the vehicle. If one cannot be found, then a jumper wire from the “- “or black terminal of the battery can also be used)
Ground both purple wires to chassis ground location. This can be performed with both wires at the same time or each wire individually. These are our trigger wires, one driver and one passenger.
When chassis ground is applied to wires it will deploy the step and when ground is removed it will retract the step.
If you are experiencing no deployment and lights for steps are not illuminating you may have a controller failure.
If steps start to deploy and retract when ground is applied and removed, then you may have an OBDII failure.
If you have further questions, please reach out to our technical support team at 1-888-983-2204
I believe my motor has failed.
If you believe you are experiencing an issue with a motor that has failed, follow the steps below:
Testing Power to Motor:
(Note: You will need a digital multimeter to perform this test)
Locate the plug at the motor.
Remove plug from the motor.
Using a digital multimeter set meter to volts DC (symbol below)
Insert the red lead of the multimeter into the orange wire black lead into the white wire of the motor plug. (Note: One side of the vehicle will have a solid orange and solid white wire and the other will have orange/black stripe and white/black stripe. If you are not able to remove the plug pierce the wire with DMM lead to complete test)
With multimeter visible open the door on the side of the vehicle the motor we are testing is located.
The meter should display battery voltage for 5 seconds and return to zero. (Note: To check for battery voltage touch red and black lead of meter directly to red and black posts of battery under the same volts DC setting on meter)
Close door and meter should display -battery voltage for 5 seconds and return to zero. (Note: It doesn’t matter if you display “- “or “+” voltage during door open or door close operation just that we are getting voltage for 5 seconds before returning to zero)
If you receive voltage for less than 5 seconds or only in one direction, we may have an issue with the controller.
If test shows accurate voltage readings, then we may be experiencing binding in the linkage or an issue with the motor.
If you want to confirm you are having an issue with your motor, simply switch the motors from side to side and see if the issue follows the motor. (Note: This step will only work if one side has failed, and the other side is working)
If both sides have failed, you can unplug the motor and manually put 12v power+ and ground- to each of the pins on the motor to check if it will move. One contact gets positive+ and the other gets a ground- and the motor moves one way, then you switch the configuration, and the motor will spin the other.

One or both PowerSteps will not deploy/retract.
If you are experiencing this issue, it may be originating from a few possible areas. Follow the steps below to help isolate where the failure may be coming from:
Controller Reset:
Locate Amp Research Controller under the hood. The controller will have a red wire going from the red + terminal of the battery directly to the controller.
Locate fuse holder on red wire going to the controller.
Remove the 30/40-amp fuse to the system.
Verify both locking clips are fully locked into the controller.
Push each one of the wires individually deep into the controller.
Let the system sit for 5 minutes.
Reinstall the fuse into the controller and retest.
If your issue is not resolved, please proceed to the next step.
Testing Power to Motor:
(Note: You will need a digital multimeter to perform this test)
Locate the plug at the motor.
Remove plug from the motor.
Using a digital multimeter set meter to volts DC (symbol below)
Insert the red lead of the multimeter into the orange wire black lead into the white wire of the motor plug. (Note: One side of the vehicle will have a solid orange and solid white wire and the other will have orange/black stripe and white/black stripe. If you are not able to remove the plug pierce the wire with DMM lead to complete test)
With multimeter visible open the door on the side of the vehicle the motor we are testing is located.
The meter should display battery voltage for 5 seconds and return to zero. (Note: To check for battery voltage touch red and black lead of meter directly to red and black posts of battery under the same volts DC setting on meter)
Close door and meter should display -battery voltage for 5 seconds and return to zero. (Note: It doesn’t matter if you display “- “or “+” voltage during door open or door close operation just that we are getting voltage for 5 seconds before returning to zero)
If you receive voltage for less than 5 seconds or only in one direction, we may have an issue with the controller.
If test shows accurate voltage readings, then we may be experiencing binding in the linkage or an issue with the motor.

PowerSteps are no longer deploying or retracting.
If your steps are no longer deploying or retracting and the LED lights for the steps no longer light up, you may be experiencing an issue with your controller or OBDII module plug if the kit is a plug and play.
Follow the steps below to help identify where the issue may be coming from:
Controller vs. OBDII Failure:
Complete controller reset procedure before performing this test.
Locate OBDII module plug under dash. This will be plugged in to the vehicles diagnostic port and look like the image below:
Follow black pigtail off side of plug till it splits in to 2 purple wires. (Note: One is purple, and one is purple/black stripe)
Disconnect purple and purple/black stripe wires from splice point under dash
Put OBDII plug to the side it will not be used
Locate a solid chassis ground location in the vehicle. (Note: Chassis ground locations can be found on any non-painted bare metal location in the vehicle. If one cannot be found, then a jumper wire from the “- “or black terminal of the battery can also be used)
Ground both purple wires to chassis ground location. This can be performed with both wires at the same time or each wire individually. These are our trigger wires, one driver and one passenger.
When chassis ground is applied to wires it will deploy the step and when ground is removed it will retract the step.
If you are experiencing no deployment and lights for steps are not illuminating you may have a controller failure.
If steps start to deploy and retract when ground is applied and removed, then you may have in OBDII failure.

Testing for binding in linkages
If you believe you are experiencing an issue with binding or seized linkages follow the steps below to test:
Clean PowerSteps following the cleaning procedure shown below:
Remove motor to the PowerStep.
The step will rest in the down position after the motor has been removed so use caution.
From the center of the board, move the step to the fully retracted position remaining cautious of any resistance in the linkage arms.
From the retracted position, keeping legs at a safe distance release board.
The board should return to the fully deployed position quickly.
If any resistance is felt in the linkages when putting the boards in the fully retracted position or if the board falls to the fully deployed position slowly then proceed to the next step.
Remove board from linkage arms.
Individually put each linkage up and down and feel for resistance or binding.
If you feel resistance or experience binding, then that linkage may need to be replaced.
If you are unsure if you are experiencing resistance or binding and you are only experiencing this on one side, then remove the board on the working side and run the same test on the other side.
Using a stopwatch, time both sides to verify that the linkages are dropping at a similar rate of speed consistently.
