NHTSA's summary
TELEMATICS CONTROL UNIT RESET AFTER AUTOMATIC COLLISION NOTIFICATION 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”.
