This guide provides a structured approach to diagnosing and resolving issues with your AMP Research Power Steps. It covers common problems, from mechanical obstructions to electrical faults, and offers practical steps for effective troubleshooting and repair.
Common Issues and Initial Checks
Before diving into complex diagnostics, start with a visual inspection. Look for any obvious obstructions like mud, ice, or debris around the power step mechanisms. These can often hinder movement and cause the steps to malfunction. Check for any loose or damaged components that could be causing the problem. Ensure that the steps are not physically binding against anything on the vehicle’s frame. Next, listen carefully for any unusual noises during operation, such as grinding or clicking, which can indicate mechanical problems. It is important to note that power step problems frequently stem from gunked-up pivots or road debris. Intermittent contact due to terminals not being correctly placed with the white rubber connector could also be the issue. If the steps are making noise, it might be due to the buildup of salt, mud, or filth. Another factor can be that the power step is catching stones, filth, snow, or ice. If the steps retract gradually or irregularly, it might indicate snow, dirt, or sporadic contact within the system. Finally, verify that the power step’s LED lights are still operational, as their failure can suggest broader electrical issues.
Mechanical Obstructions and Cleaning
Mechanical issues are a common culprit behind power step malfunctions. Begin by thoroughly inspecting the hinges and pivot points for any obstructions. Debris such as mud, dirt, salt, snow, and ice can easily get trapped in these areas, causing binding and preventing smooth operation. Use a pressure washer or a hose with a nozzle to remove any accumulated grime. For stubborn buildup, a brush or a soft cloth may be necessary. After cleaning, apply a lubricant like WD-40 to the hinges and pivot points. This will help prevent future binding and ensure that the steps move freely. Make sure to check the plastic cups that hold the bumpers, which soften the impact of the arms on the steps; if these are flat, they should be addressed. Manually deploy the running boards by opening the door and then placing your foot on the step, allowing for easier access for cleaning. Remember that regular cleaning can prevent many common problems associated with AMP Research Power Steps. Always make sure that the steps are free from debris before each use.
Electrical Connections and Fuses
Electrical issues can also cause your AMP Research Power Steps to malfunction. Start by checking all electrical connections for proper fit and security. Ensure that the white rubber connectors are properly seated and that the terminals are in the correct place, as intermittent contact can be a common problem. Locate the inline fuse on the harness, often near the positive terminal on the battery, and verify that it is not blown. If it appears okay, try replacing it with a new 30A blade fuse to rule out a hidden failure. Inspect the wiring harness for any signs of damage, such as cuts, abrasions, or corrosion. A loose or damaged wire can disrupt the power supply to the steps. Check the controller module under the hood, as it should not be warm to the touch and can indicate problems. If you have a multimeter, verify the power supply to the step motor. Ensure all connections are clean and free of corrosion. If all connections are good, there may be an issue with the relay.
Controller and Module Problems
If the electrical connections and fuses are in order, the next area to investigate is the controller or module. The controller acts as the brain of the power step system, so any issues here can lead to malfunctions. Start by locating the AMP Research Controller, typically found under the hood. Check for any visible damage to the controller box, such as cracks or water damage. If the controller is warm to the touch, this may indicate a problem. Sometimes, the controller software may crash or lose communication with the OBD system, causing the steps to stop working. A simple way to troubleshoot this is to remove and replace the fuse for the controller; this can reboot the controller and restore functionality. If removing and replacing the fuse always restores operation, it may suggest the controller needs attention. For more specific troubleshooting tips, refer to the AMP Research website, where you can find diagrams for your particular model. If you have an OBDII module, check that connection. If the system still does not function correctly, the controller may need replacing.
Motor and Actuator Issues
If the controller and electrical connections are in good order, the next area to inspect is the motor and actuator. These components are responsible for the physical movement of the power steps. Start by listening for any unusual noises when the steps are supposed to deploy or retract. A ticking noise when the step is fully deployed or retracted may suggest a problem with the tolerance ring/clutch assembly, which may require replacement. If you hear the motor engage but the steps do not move, this could point to a problem with the actuator. Check for any visible damage to the motor or actuator, and ensure that there are no obstructions preventing free movement. The motor itself could be failing, particularly after several years of use. If you suspect a motor or actuator issue, it’s best to refer to the AMP Research website for specific diagrams and replacement part information. You may need to consider professional assistance to replace these components. Also, review the troubleshooting guide on the AMP Research website for your specific model to ensure correct steps are taken.
Door Trigger Signals and Wiring
The power steps rely on accurate door trigger signals to know when to deploy or retract. Problems here often manifest as the steps not deploying or retracting correctly when a door is opened or closed. Start by examining the door trigger wires, usually connected to the vehicle’s door ajar circuit. Ensure these wires are securely connected and free from any damage, such as cuts or corrosion. The door signal wiring, especially on some newer vehicle models like the Ford Raptor, may differ from standard configurations, so verify that your connections match AMP’s instructions for your specific vehicle. If the steps are intermittently working, then the issue may be from a loose or faulty connection. Use a multimeter to test for continuity. Another area to inspect is the connectors at the AMP Research Power Module. WD-40 can be applied to these connectors to remove any potential corrosion. The door signal wires are critical for the system to function correctly. Always verify that these wires are in good order.
Resetting the Power Step System
A system reset can often resolve many issues with your AMP Research Power Steps. This process typically involves interrupting the power supply to the control module. The most common method is by locating the fuse for the power steps, and removing it for a few minutes. This allows the system to reboot, often clearing any temporary glitches or software errors. If your system is connected via an OBDII quick plug, unplugging this can also achieve a similar reset. After a few minutes, reinsert the fuse or reconnect the plug. The power steps should then attempt to cycle. Sometimes, when the doors are open, and the power is interrupted it can cause the steps to get stuck in the deployed position, so be sure to test them thoroughly after a reset. If the reset does not rectify the problem, there may be an underlying issue that requires further troubleshooting. This can also indicate issues with the controller, and in such a case, you will need to pursue further diagnostics. This procedure is not a substitute for repair, but a way to clear possible temporary issues.
Warranty and Replacement Parts
AMP Research typically offers a warranty on their Power Step systems, often covering parts for a specific period or mileage. It is important to consult your warranty documentation for the exact terms and conditions, and understand what issues are covered and for how long. The warranty may not apply if specific labor, parts, or service required for proper function is declined. If your steps are under warranty, contact AMP Research or an authorized dealer for assistance with repairs or replacements. If your warranty has expired, replacement parts can be purchased, but ensure they are genuine AMP Research components for proper fit and function. Some common replacement items include clutch assemblies, control modules, and motors. When looking for parts, ensure you have your power step model number to find the correct compatible components. Be aware that using non-genuine parts may void any existing warranty or cause issues with the system. Always use the correct parts when repairing or replacing the AMP Power Step system, if you are unsure, consult a professional.
