AMP Research (AAM Group or Automotive Accessories Marketing) is in the manufacturing business of power steps with unique features that set them apart from their competition. However, that doesn’t mean they don’t run into an occasional glitch and don’t perform well.
Here’s a list of common problems.
AMP Research Power Step Diode and Fuse Locations
The beauty of AMP Research power steps is that they’re electronically powered into action when the door opens. They close on their own accord. When they fail, it’s essential to locate the diode and fuses.
A fuse is a safety device that protects an electrical circuit from overloading. Consult your vehicle’s owner manual to find the fuse you need to disable to install the power step.
A diode is an electrical component that directs a current in one direction. Look for the diode near your vehicle’s alternator (or electric generator); next to it is the diode. Diodes are cylindrical parts with stripes that control the current flow.
To install an AMP Research power step, access their manuals for help. There are many helpful how-to videos.
Common AMP Research Power Steps Problems
Power steps are a great invention when they work well. However, sometimes they don’t operate how they should or refuse to work. Here are common AMP Research Power step issues and what are potential causes.
1. For debris build-up when your power step makes weird noises during opening or closing. Salt can become a problem in winter and crust over the operating mechanics. The same is true for mud from driving in wet and muddy conditions.
2. Similar to the first cause, stones, dirt, snow, and ice can affect the operation of a power step. When the power step is sluggish and doesn’t operate at its usual efficiency, those could be causing the problem.
3. Intermittent contact is caused by the terminals not connecting because they’re loose, faulty, or corroded.
4. When the step opens or closes part-way, it might be due to contact points sticking.
5. You might have a swing arm problem if the side running board step retracts too far.
6. The step stops at the wrong position with the door closed.
Noise
With constant use and neglect, the AMP Research power step can start to make unusual noises. Our ears intuitively recognize when something is wrong.
Most often, the problem is debris build-up. Mud, road dust, and even salt can create problems for the inner mechanics of a power step. Weather conditions can impact how much debris gets embedded in the operating gear.
A great place to fix this problem is the handheld car wash. The first step is to release the step manually, which typically takes a bit of force.
Spray the running board front to back but avoid the actual motor. While the motor housing can absorb wet conditions, don’t spray it directly. Make sure you rinse the hinge thoroughly. When the running board and hinge are clean, generously apply a silicone lubricant.
However, do not allow lubricant to coat the actual stepping surface. Wipe any overspray with a rag to avoid slipping.
Sluggish Movement
Like the noise problem above, debris can also affect how the running board mechanism retracts and opens. If debris lodges in the operating mechanisms, it’s possible to get a step that moves but does so sluggishly.
The common culprit is dirt, mud, or snow and ice. In extreme weather, it’s easy to see the build-up of ice and slush. Sometimes a few well-placed kicks with a boot can loosen large chunks, or a good wash will help solve the problem.
Rarely will you have to climb under the vehicle unless you don’t have access to water and it’s freezing.
Intermittent Contact
This problem comes and goes. One moment, the step lowers like usual; the next, it struggles to operate and open fully. Intermittent contact means there is a loose connection. The most logical place for this fault is where the controller connects to the wire harness.
You get intermittent operating functions when the terminals have a loose connection. Check to make sure the connections are secure and clean. A small piece of dirt wedged between contact points can cause this problem. Tighten as needed.
Typically, when the truck or car rides through punishing terrain for work or fun, these connections can come loose over time from repeated jarring.
Intermittent Operation
Some users of the AMP Research power step report an issue with the step deploying when the door is open or there is a delay. This can have potential safety problems for anyone quick to jump from the vehicle without looking.
This fault sometimes makes the contact points sticky with oily, dirty residue. It’s possible to clean the connection points with a cloth. If that doesn’t solve the problem, sometimes the whole module needs replacing.
Depending on the situation, you might have a warranty or not. It’s always a good idea to keep track of aftermarket purchase receipts in a folder. Many AMP Research products have a 5-Year Limited Warranty (see page 18).
Retracts Too Far
Sometimes the running board retracts too far under the truck and gets stuck beneath. When this happens, it’s a sign that the swing arm is malfunctioning or broken. It could also be a faulty stopper. The stopper and swing arm work in tandem. If one part breaks, it might cause the step to retract too far underneath.
Unless you’re mechanically inclined, you might need a professional repair job. You will need a better stopper or a replacement motor to handle the task.
Incorrect Step Position
When the door shuts, and the step doesn’t fold into the correct position is another common problem, especially in trucks with shock sensor security features or added extras. It means something interrupts the power step from returning to its correct position.
This problem is simple if you know how to reset the settings for your shock sensor. Once you adjust the sensitivity level, the problem should fix itself.
Are AMP Research Power Steps Worth It?
AMP Research power steps are an excelling running board stepping system. Most problems with these power steps are from poor maintenance or environmental issues like snow and dirt and are easy to fix.
Amp Research power steps are worth the expense. They might even save wear and tear on your knees.
