Unit flashes 5 times with hood closed

Question

2010 toyota prius. Did install and it worked fine. Next day came back because it wont start. Lights flash 5 times indicating hood open. I disconnected hood switch and issue persists. Reprogrammed unit to the vehicle and it works again. Possibly bad unit? Service number 001a07 016839

Answer 1

2 reasons why you can get 5 flashes

1. Module detects hood open via CAN
2. DARK BLUE (A8) is at ground.

Vehicle does not have factory hood pin. I even disconnect the dark blue wire and it still did it

Turn OFF A11

Ok, thanks

Answer 2

I was stumped until I read this answer, and realised this 2013 Sonata has a failed factory hood switch! Removed it completely so some well meaning person does not plug it in again. Notified customer that is should be replaced, I'm sure they never will.
