Not heard of that one.
By all lights, what do you mean?
The factory trailer module is connected to the CAN, so only does what it's instructed to do by the CJB.
Hi, by all lights I mean they go in a sequence with each set of lights going on for a few seconds one after another. It is then easy to see if one or both bulbs are not working. Lights, brakes, signals, fog and reversing. All one after another. Even my 7 year old grandson can now check them for me. (Although I still do a quite look myself). I have no idea what your talking about on the CAN or CJB so cannot help you there.
I've not seen a light show on mine, but then I generally don't connect the trailer plug with the lights on. Mine has a genuine trailer module and harness installed.
