Replacements Of ECM: Notes
If the ECM fails or is defective, the unit must be replaced with a "virgin" or "neutral" ECM. All keys will have to be registered (taught) to the new ECM. Keys not taught to the new ECM WILL NOT work with the ECM (Refer to TEACHING PROCEDURES ).
NOTE:
The vehicle specific data will have to be left unchanged with regards to the unique programming for the transponder.
