Yeah, it could be done, but why not disconnect the battery? It would be easier.

These codes are kept in memory for 40 warm up cycles. To clear the codes for purposes of testing or confirming repair, perform the code reading procedure. When the fault codes begin to be displayed, de-activate the test by either disconnecting the jumper wire or releasing the test button on the hand scanner. Stopping the test during code transmission will erase the continuous memory. Do not disconnect the negative battery cable to clear the codes; the keep alive memory will be cleared and a new code (19) will be stored for loss of PCM power.
