L322 K-Bus error

spitfire · Mar 3, 2014

Hi All,
Still suffering with a dead Range Rover but hopefully now the allcomms kit has arrived I can get to grips with the problem.
Most of the modules won't 'link' with the computer, the few that will I have managed to read and reset the faults. The main fault that won't reset is a K-bus fault on the Instrument pack. Currently the alarm is on constantly and I can not open any of the doors other than the drivers door with the key. Most of the buttons on the dash won't work, or do strange things when depressed. I think it may be a BCU problem but until I've fixed the K-bus issue I can't communicate with it.
Any help gratefully received.

Regards
Ian

+1 Duff BCM

Also check the rear sat nav unit / amps for damp

+1, sounds like water in the electronics.

Hi Just Bumping this post as we have now found the fault.
Headlamp levelling ecu found to be underwater in the nearside A post. Took out the unit, dried out the area it fits in, and cleaned the plugs and connections. Ecu miraculously appears to be still working and the car is now working perfectly. All EAS faults gone, power steering now as it should be and all functions restored. Just need to find out where this water is coming in from. Power drain also sorted, so looking forward to getting a few miles down over the weekend as it has been stuck on the drive for weeks.
Many Thanks for all who contributed. Cheers Ian

Check the windscreen / sunroof drains aren't blocked

Yet another leak point.

Bonjour.
Le calculateur de mise à niveau des phares a été trouvé sous l'eau dans le montant A du côté proche. Sorti l'appareil, séché la zone dans laquelle il s'insère et nettoyé les fiches et les connexions. L'écu semble miraculeusement fonctionner encore et la voiture fonctionne maintenant parfaitement. Tous les défauts EAS ont disparu, la direction assistée maintenant comme il se doit et toutes les fonctions restaurées. Reste à savoir d'où vient cette eau. La consommation d'énergie a également été triée, alors j'ai hâte de parcourir quelques kilomètres au cours du week-end, car elle est bloquée sur le lecteur depuis des semaines.
Un grand merci pour tous ceux qui ont contribué. Bravo Ian

Translation for the anglais.
The headlight leveling computer was found underwater in the near side A-pillar. Take the device out, dry the area it fits in, and clean the plugs and connections. The ecu miraculously seems to work again and the car now runs perfectly. All EAS faults gone, power steering now as it should be and all functions restored. It remains to be seen where this water comes from. Power consumption has also been sorted, so I'm looking forward to putting in a few miles over the weekend as it's been stuck on the drive for weeks.
A big thank you to everyone who contributed. Well done Ian
