Generic code readers can sometimes misdiagnose manufacturer-specific codes. To properly interrogate the modules, you need a professional tool like a JLR SDD (Jaguar Land Rover Software Driven Diagnostics), IIDTool, or high-end systems like Autologic. You need to look not just for B1D9F-11, but for secondary codes (like U2300-54 for the BCM or codes for the AAM) to get the full picture.
