AMP Research Replacement Smart Series PowerStep Controller

Restore Your AMP Research Smart Series PowerStep When the Controller Fails or Gets Damaged

The AMP Research 19-04732-SSA is the factory-replacement Smart Series controller for AMP Research PowerStep running boards equipped with the Smart Series module. This is the electronic brain that manages the automatic door-triggered deployment and retraction cycle of your PowerStep boards, as well as the smartphone app override function that allows you to lock steps up or down from your phone. When a Smart Series controller fails due to water intrusion, electrical damage, or age, this OEM replacement restores full function without replacing the entire running board system. The 19-04732-SSA is vehicle-make and model specific in its programming, so confirm you are purchasing the correct SKU for your exact vehicle and PowerStep model before ordering. It also replaces the older AMP Research A-04 and A-06 style controllers on eligible applications.

Frequently Asked Questions

The 19-04732-SSA is the electronic control module for AMP Research Smart Series PowerStep running boards. It monitors the vehicle's door switch signals and commands the step motors to deploy when a door opens and retract after the door closes. It also enables the Bluetooth smartphone app override function, allowing you to lock the steps in the up or down position and control integrated or auxiliary LED lights from your phone.

The Smart Series designation applies to AMP Research PowerStep kits sold with app control capability. Look at the model number printed on your existing controller or on your original PowerStep box. If the controller is labeled SSA or was sold as part of an 86xxx-series Smart Series kit, the 19-04732-SSA is the correct replacement module. If your steps are an older non-app model, your controller will have a different part number.

The 19-04732-SSA controller is listed as a universal Smart Series replacement, but AMP Research notes that PowerStep parts are specific to the vehicle make and model and the series of PowerStep installed. Always confirm that your specific PowerStep kit lists 19-04732-SSA as its replacement controller part number before ordering. You can verify this by looking at the parts diagram on AMP Research's website or in the documentation that came with your PowerStep kit.

The 19-04732-SSA is noted by AMP Research as a replacement for the older A-04 and A-06 style controllers on compatible applications. This means some earlier non-Smart-Series PowerStep installations may be upgradeable to Smart Series app control using this controller, provided the wiring harness is compatible. Confirm with AMP Research customer support before purchasing for an A-04 or A-06 replacement.

Possibly. If the steps are stuck down due to a failed controller, replacing it will restore normal operation. However, steps can also stick due to failed motors, damaged wiring, or corroded connectors. Before replacing the controller, check for power at the controller connector and listen for motor noise when a door is opened. If the motors are silent and power is present at the harness, the controller is the likely fault. If the motors hum but the steps do not move, the motor or mechanical linkage may be the issue instead.

AMP Research provides installation guidance for PowerStep components on their website. The replacement controller is a direct module swap on most applications. Locate the existing controller (typically mounted in the door jamb area or under the vehicle near the steps), unplug the existing module, plug in the replacement, and verify operation. AMP Research's online installation guides are model specific and can be found by entering your vehicle and step model on their support site.

AMP Research provides a 5-year limited warranty on PowerStep products and replacement components when installed according to their instructions. This warranty covers defects in materials and workmanship. It does not cover damage from improper installation, water intrusion due to incorrect mounting, or physical damage. Retain your purchase receipt and register your product on the AMP Research website to activate warranty coverage.

In some cases yes, as the 19-04732-SSA replaces certain older A-04 and A-06 controllers. However, a full Smart Series upgrade may also require updated wiring harness components to support the Bluetooth antenna and app communication functions. Contact AMP Research technical support with your PowerStep model number to confirm what additional components may be needed for a complete upgrade to Smart Series operation.

The AMP Research PowerStep controller is typically mounted in the door jamb pillar area, rocker panel cavity, or along the inner sill near the running board motor assembly. The exact location varies by vehicle make and model. Refer to the installation manual for your specific PowerStep kit number to find the controller location diagram for your application.

Installation Instructions

1. Identify the location of your existing AMP Research Smart Series controller by consulting the installation manual for your specific PowerStep kit number, or by tracing the wiring harness from the step motor toward the vehicle's door jamb or sill area.
2. Disconnect the negative battery terminal before disconnecting or connecting any controller wiring to prevent electrical faults or short circuits.
3. Unplug all harness connectors from the existing controller module. Note the orientation and position of each connector before removal.
4. Remove the old controller from its mounting bracket or location. Note how it is secured (clips, screws, or adhesive).
5. Mount the replacement 19-04732-SSA controller in the same location using the same mounting method as the original.
6. Reconnect all harness connectors to the new controller in the same orientation as the original. Ensure each connector is fully seated and latched.
7. Reconnect the negative battery terminal.
8. Open and close a vehicle door to verify that the steps deploy and retract correctly.
9. Download the AMP Research app on your iOS or Android device and pair it with the new controller to verify app functionality.
10. Confirm that LED lights activate and deactivate with step deployment if equipped.
