Specs At A Glance

Good To Know

Q: Does this module need programming after installation? A: It connects to the existing Powerstep harness as a plug-in replacement, so no dealer programming is typically required. Confirm the controller designation on your old unit matches A-04 or A-06 before ordering.

Q: Why did my original controller fail? A: Power step controllers commonly fail from water intrusion, corroded connectors, or voltage spikes in the step circuit. Inspect the harness and mounting location for damage when installing the replacement.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
