Parking assist and parking distance control issue
 

Hi all
would like to ask if those two systems work from aux battery?
i book my car to dealer but curious myself how it works.
car was dysfunctional for a few month, main battery was dead and replaced with new one but don't know about aux, maybe dead as well and caused the problems
my local garage OBD does not shows me if any of PDC sensors faulty, as I know one failed and whole system stop working. Is it true??
thanks

park assist works with the engine (both when u are in the car or outside)

let system find a parking.
when it show parking come to full stop

now you have 2 options:

1) staying in the car: select the spot & follow onscreen instruction

2) remote parking: put car in park and then select spot.
get out of car & connect remote app to car & follow instructions
