So do you know if the fault-sense wire carries a signal indicating successful illumination or does it send a signal indicating failed illumination?Mike, outstanding!!!!!
It all makes sense. When the Jeep is asleep and you reach in with the broomstick handle and press the pedal, there is no current flowing to the lights, and therefore nothing to flow back up the fault-sense wire to the BCM. Conversely, when you apply the brake lights via the RV, the RV supplies power to the light and that circuit board communicates back to the BCM via the fault-sense wire... which triggers the wake-up.
It seems like it must be a success signal but when I remove those pins, I don't get any errors or messages from the Jeep indicating the tail light is faulty.
