Thats the only new thing I did recently ….Charger for the phone .I have the optimate 0-100 SAE to USB adapter plugged in to the charging pigtail .You think this charging is related to the pin code and why ?I also tried the pin last night …..for me it wasn’t last 4 digits of VIN ,it was 0000 as I tried to modify pin through settings .I had to go to settings,modify pin as it wasn’t prompting for code again but I needed to know the pin ,just in case it happened again. .As I was writing this message,I was on phone with the dealer.The tech said it could be something on the keychain (a fob,ez tag /Some chip) which interferes with Bike immobilizer antenna and it prompts for the pin code.According to him ,if the black key doesn’t work once,it should always ask for pin and not intermittently.
So in my case ,it wasn’t the key fob or tag ,it was my phone mounted on handlebars right next to ignition and these phones have NFC chips/all the antennas/Wi-Fi/Bluetooth etc, which could have interfered with immobilizer.?Anyone has any idea if that could be the case of interference with immobilizer antenna?
