Recurring Fault Code 41739(0xA30B)
« on: August 28, 2016, 07:46:02 PM »
2012 R1200RT SE

I get the above code every scan.
Horn open circuit
The horn works fine. I have a Stebel Nautilus fitted using a canbus connector from Nippy normans. The fault clears and a rescan will be clear. However at the next scan it is back.

I get the same codes with my K1600GT.

Like you, I changed away from the standard horn and fitted a dual horn using the horn power to switch a relay through which the horns are connected.

My thoughts are that the bike is not now seeing the correct current draw when the horn is operated due to only powering a relay and therefore thinks the horn is open circuit.

Working on that assumption, I can live with the fault codes.

I guess if I knew the correct current draw I could add a resistor to correct the fault but it's such a minor thing, I haven't bothered.
