Immobilizer activated when I hit a bump on the road and now my truck won't start. Security light continues to flash then once I try to start the truck it is on steady.

Hello,

Can I ask if you have bright headlights? I want to know if the battery is okay. Please turn the headlights on for 10 minutes they should still be bright when the time is up. Lets turn to reset the system. please follow this guide:
