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 and the TCU must be reset to re-enable the
automatic collision notification function. Some models will store DTC B2E1B-97 (Automatic
eCAll locked) as “CURRENT” when this function is disabled.
This bulletin describes how to reset the TCU after an automatic collision notification has
been performed. For models with B2E1B-97 (Automatic eCAll locked) set as “CURRENT”,
complete the SERVICE PROCEDURE starting on page 2, and then erase DTCs after
confirming TCU condition is “UNLOCK”.
Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Infiniti retailer to determine if this applies to your vehicle.
