Hondata

I'm going to make a short story about the problem...
I lend my friend my battery while my car is in storage but he gave me back the wrong one (we have the exact same looking expect for the negative pole ...)

So i plugged it the wrong way... After i realized nothing worked i took back mine(the good one) and plug it. Every thing look like working radio climate control cluster fuel pump etc, even the light next to the usb plug on the kpro

So now i cannot connect to kpro anymore it always say driver not connect i try updating driver but no success.

Is there any fuse i could have blown or did i just messed up the ecu...

I didn't try to start the car i was more concern about why i could not connect to kpro

Any help would be appreciate

Check all your fuses, if there are none blown you have probably damaged the ECU or the K-Pro.

I'm going to bring my ecu to my local hondata dealership hope i haven't damaged it :(

I went to my local hondata dealer and finaly the ecu and kpro wern't damage OUFFF :P

Hes said it was my laptop the problem and to uninstall kmanger then redownload it and should work !
