How it works

The Range Technology RA003B plugs into your vehicle's OBD-II diagnostic port and communicates with the vehicle's electronic control systems.

If desired, simply unplug the module to restore the vehicle's original AFM/DFM functionality. Always verify your vehicle's compatibility before installation.
