2009 LC MFD Panel Switches (MAP, MENU, INFO) not working
I’m hoping that someone could suggest the next steps. Every other MFD Panel Switch is not working (MAP, MENU, INFO), perhaps the pattern is of significance. I went into the “secret menus” and didn’t find error codes. Additionally, when I perform the Panel Switch check, no sound is emitted when I press any of the buttons, both working and non-working buttons. I don’t have access to the INFO screen, but I did see online in the upper right corner of the INFO screen a button to turn beep on/off. Perhaps mine is turned off, however you would think that after resetting the unit it would return to the default and beep when the buttons are pressed.
I performed MFD reset in several ways, disconnecting negative terminal for a period of time and pumping the brake pedal 10 times, disconnecting both positive and negative terminals and having them touch for 60sec. I took the MFD apart, expecting to find mechanical issue with the buttons or loose connection, but didn’t. The Panel Switch circuit board shows number 718X28 36. I reassembled the unit, no change, issue is still present.
I didn’t check the fuses yet. This is my next task. Perhaps someone can direct me to a specific fuse(s) to target.
Thanks in advance
