I'm having a charging issue with my 2011 LR4. I got a battery light and not charging message while driving. I hooked up my Gap tool and found that at idle the alternator load was 100% with minimal accessories on. After checking the basics, I replaced the alternator and battery with an OEM Denso and Odyssey AGM.
I reset the battery in service life and initially everything worked great. The same alternator load reading at idle dropped down to 23% from 100 but after a couple of test drives the voltage reading dropped down to battery voltage. This time without any warnings on the I-Pack. After checking I found in the BCM, fault code B11DB-87 Battery Monitoring Module - Bus Signal/messsage failure. Anyone have experience with this fault?
