Intermittent remote start


Recommended Posts

If you currently have this problem disconnect the battery for 15 seconds and reconnect. This will likely solve it however if this a reoccurring issue then it will probably happen again.

 

You don't have anything hooked up to the diagnostic port do you or access the vehicle programming via the diagnostic port?

Actually, that would be good knowledge to have. What exactly DOES a battery disconn reset? I would assume all radio presets and settings (fade, balance...) and also any destinations/routes saved in Navigation, also probably climate settings? Anything else?

Radio presets & its settings don't reset, also destinations/routes saved in Navigation should not. Climate settings? what settings? you only have the last setting and it will reset to default set temp but you just change normally.

 

Anything else? The left display settings in the instrument cluster will reset some settings like the "menu memory will revert to default with no memory, enhanced trip computer will revert to the simple setting and the vertical tach display will revert to not being shown. Also the miles to empty might change to be based on a set default mileage instead of your actual average for the past few hundred miles.

 

The engine idle & transmission shift calibrations will also reset, but they adapt quickly after driving.

 

Actually it is a good thing to do, disconnecting the battery every once in while to reset the car's electronics. Just like you PC or smartphone.
