Auto step just stopped working

Yep.

It seems like a no-brainer to suspect and check this switch first if an automatic step stops working.

But I guess it may depend upon in what way the step stops working. My automatic step has at least a couple of different operating modes and maybe some of the modes don't require inputs from this switch. :h

The step requires the Proximity(magnet door switch) to function regardless of step brand and features. For instance, if the Magnet switch is defective and you close the door and start the engine, the step WILL NOT retract as designed. Doug
