Enhanced Accident Response (Highline CTM Only)

ENHANCED ACCIDENT RESPONSE (HIGHLINE CTM ONLY)
If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the PCI bus to the CTM module to unlock the doors. The interior lights will be turned on when the vehicle speed message on the PCI bus indicates 0 mph or the message is not present. In addition to unlocking the doors, the door lock feature will be disabled for a predetermined amount of time following the deployment. Once the ignition key has been cycled to the "off" position, normal operation will resume.
