SERVICE INFORMATION
The Telematics Control Unit (TCU) has the ability to send an automatic collision notification when the vehicle is
involved in an accident. Once an automatic collision notification is performed, the function becomes disabled.
The TCU must be reset to re-enable the automatic collision notification function.
This bulletin describes how to reset the TCU after an automatic collision notification has been performed.
