A failing battery can throw a lot of faults like these. What’s the voltage after shutdown and in the morning before starting? As you are getting similar faults from other system ECU’s this is a strong indicator. 2012 TDV8 Vogue (L322) |

Thanks, yes I know what a failing battery can do, this one is pretty new and the charge is around 14.5 or 15. This whole thing is really a communication fault due to the rlcm or can bus faillure, but I haven’t got a clue what to do… |

Try disconnecting the battery and doing a reset by holding the leads together for a minute or so.

First thing I would check is whether the RLCM is plugged in, clean the connector and trace the wiring that everything is ok. Perhaps also check whether the heights are calibrated correctly as it may just have thrown it out of tolerance.
