Answer 1

The way to reset the ECM is with a scan tool or a code reader, that or provided the correction is resolved the ECM will clear the code at least within 4 ignition start up, It is not a good idea to disconnect the battery doing that you need a scan tool that can do a transmission relearn. and a battery reset.
