Frequently Asked Questions
Straight answers on specs, fit and support
Will this fix steps that only work sometimes?
A loose or damaged OBD-II module is one common cause among several. Owners report cases where a new module did not fix the fault, so it is worth confirming the diagnosis with AMP Research tech support before ordering.
I moved my steps to a newer truck. Do I need a new module?
Often, yes. Modules are specific to the vehicle, and owners who moved a set to a newer model year have needed the module for the new truck. Order by the vehicle the steps are fitted to now.
Is it plug and play?
The module plugs into the vehicle's OBD-II port, but it connects to the PowerStep harness, and some wiring is required.
Are the connectors in the photo included?
Order by what the listing names. One owner found the connectors pictured were not in the box and had to make the connections another way, so plan for that.
What is the pass-through version?
Two listings are pass-through harnesses rather than modules. They let the PowerStep share the OBD-II port. The title says which part each listing is.
Is there a warranty?
AMP Research describes its replacement OBD-II modules as backed by a limited warranty but does not publish the term on the product page. Contact us for details.
