[rxom]

Hello there :

how could we do to swiths on the air suspention since we can't turn on the car ?

Thanks in advance,

Rom

Does the computer wake up? If not try putting a slow charger on the 12v battery.

yes, we manage to have the computer on (the 2 screen) but nothing happened...
and when we put the foot on brake, nothing more. i try also the jack mode, but can't trigger it.

I had a similar problem when my 2013 had to be towed due to the HV battery getting water in it. I popped the grill off and connected a batter jumper to the leads to charge the 12V battery. It allowed me to put the car into jack mode and raise the suspension.

Disconnect the fireman loop and 12v. If the 12v doesn't hold a charge then bypass to a better 12v. Reconnect and try again. If there was a collision then a fuse may have blown.
