Thread: LED modules vs load resistors

Triggers the electrical pulse that looks for a resistive load on the trailer indicators, indicating a trailer is hooked up.

Applies to the D4 only

I'm sure I read it on this forum somewhere. My experiments yesterday seem to verify it is true. If I close the door, plug in the trailer with resistors then get back in and close the door again, the reversing sensors are silenced. If I don't cycle the door, the trailer flasher in the dash works, but the reversing sensors also work. My thinking is that it is more likely that the tow assist (and other smart things) is activated when the reverse sensors are off.
I guess the bottom line is that the resistors do the job.

And now I've read Ferret's post, so yeah, that.
