My bet is was just a power glitch or a corrupted message that raised the alarm and that your unit is OK.  If the error reoccurs then you may have a hardware problem.
There is an undocumented message that you can send to the unit to set the allowed range of the EFC signal.  Default for the Tbolt is around +/- 5V or +/- 6V.  Most Tbolts seem to run with the EFC around 0V or 3V.
