Hi, I have a 2012 Civic EX coupe with standard imid and Bluetooth HFL.
The issue I'm having started this evening while Doordashing, I had to disconnect from the HFL via my phone (Samsung Galaxy J7) to speak to a customer, afterwords my phone would no longer connect to HFL.
I tried resetting the phone and turning off/restarting the car multiple times to no avail>
I finally decided to delete the settings saved for the phone in the HFL settings, only to find that every time I tried it would freeze up and become unresponsive to any and all input except to return to the base imid screen. Same thing happens when I tried to "clear all data" from the HFL menu, it freezes up and does nothing and the settings are still there.
I'm about ready to go full nuclear and pull the car battery and every last ******* fuse to reset this bitch, but that would be kind of annoying if I reset something else related to the car, such as, say, the maintenance minder. So is there a way I can cut power to the HFL system specifically so I can hard reset it?
If this were a normal computer malfunctioning in this way this would be my last ditch "pull the plug and hard reboot" troubleshooting step before giving up and calling a senior IT (I myself am a junior IT guy) Unfortunately I'm not sure what such an action entails on the car.
EDIT: So basically, what was happening was any time I clicked "Yes" or "OK" on any of the confirmation screens for deleting information or pairing new phones with the HFL, the system would freeze, the only way to get it to respond was to back out of the option you just selected and incidentally cancel the operation. So, was effectively stuck. I eventually decided "**** it" and disconnected the car battery for about 30 minutes. The HFL system ended up resetting to default amongst other things but at least everything is working and I was able to pair my phone with no trouble. I have to go through the vehicle information tomorrow and make sure settings such as maintenance minder and my door/key/lights settings haven't been reset, and I have to rebuild my speed dial/voice tags list, but since I only have 3 or so people I bother using that for it shouldn't be too hard.
What a waste of a perfectly good Tuesday evening.
