2017 RR v8 SC. Showing that Vehicle stability control it's not available on dash. Familiar with LR's as I have 2 LR3's and this usually points to a battery/alternator issue. It has a newer battery and my Gap tool is in my other LR3 200 miles away. Any pointers of where to start looking to fix? I don't even know where to see the voltage if there is a screen for it on this.
