Lexus ES: Acn Call End



This function terminates the ACN (Automatic Collision Notification) to the telematics provider. After a collision in which the DCM receives "Collision Detection Signal", the vehicle will send the emergency call notification to the telematics provider until the emergency call cancellation utility has been run, or the mobilephone battery (if equipped) is depleted. Use the emergency call cancellation utility to stop the ACN call.
