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 ACN call end utility has been run, or the BUB (Back-Up Battery) (if equipped) is depleted. Use the ACN Call End utility to stop the ACN call.

NOTE:
The BUB (Back-Up Battery) must not be replaced while an ACN call is in progress.

HINT:

After ACN call end utility has been completed, BUB (Back-Up Battery) must be replaced.
