I know a lot of people that have the GAP tool find these codes with their LR3’s. Body Control

• B1B02-28 (2F) Low frequency coil - General signal failure - signal bias level is out of range/zero adjustment failure
  ( on 25-10-2022 21:13:48 at 162221 mi )
• B1BA0-66 (6C) Excessive challenge requests or start attempt in storage mode - Algorithm based failure - signal has too many transitions/events
  ( on 25-10-2022 21:16:41 at 162221 mi )
• B1C57-14 (6C) Passive start ignition relay coil circuit - General electrical failure - circuit short to ground or open
  ( on 25-10-2022 21:13:49 at 162221 mi )
• B1D12-15 (2E) Volumetric alarm power circuit - General electrical failure - circuit short to battery or open
  ( on 25-10-2022 21:15:12 at 162221 mi )

I have these codes too. I want to know what people know about these codes? After researching these codes for a while too long. I find no solid answers as to what these codes are and or why they come up In the Land Rovers diagnostics system. Everyone seems to ignore them as if the Engineers messed up and didn’t care to rectify the problems. People assume these codes mean nothing. I don’t believe this, I feel a thrown code is here because there is some system or program malfunctioning. Does anyone have any inside story on these codes and why they appear?

 

I have a lot of those codes but it doesn't seem to affect the vehicle at all. Any progress in your investigations in the last year?
