RX450H SE-I 2009 GPS cable location/ B15C1 fault code

[Gyorgynasz]

Hello everyone, I recently purchased a Lexus RX450H SE-I 2009.Upon inspecting the factory system, I encountered an issue with the B15C1 code. I attempted to reset it, but unfortunately, it did not work. I believe the primary cause of the problem is a broken or damaged cable. I have two questions:1. Where is the location of the cable?2. Are there any alternative solutions to resolve this issue? Thank you for your assistance. Best regards,George
