ACN Call End [06/2015 - ]

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 ACN call end utility has been run, or the mayday battery (back-up battery) (if equipped) is depleted. Use the ACN Call End utility to stop the ACN call.

HINT: 

After ACN call end utility has been completed, mayday battery (back-up battery) must be replaced.
