The purge-free cells are constructed similar to certain purge-normal cells. The purge-free cells can be monitored by the DRB III(R) Scan Tool. The only
difference between the purge-free cells and normal adaptive cells is that in purge-free, the purge is completely turned off. This gives the PCM the ability
to compare purge and purge-free operation.
