I already did a search, but it provided various opinions.
My question is this:
If a CEL comes on, then you fix the issue, can you clear the ECM (or whatever it's called) by simply disconnecting the battery??? I know it resets the light on the dash, but does it also clear out the error code from the ECM???? Or, will the ECM have to to be cleared using a OBDII(?) tool???
