WARNING: This page is about a different car, the 2002 Oldsmobile Intrigue and 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.

Powertrain Control Module (PCM) uses an Electrically Erasable Programmable Read Only Memory (EEPROM) to store software and calibration information. EEPROM is not replaceable, PCM must be replaced. Replacement PCM does not contain final program information. Replacement PCM must be programed. If replacement PCM is not programmed, DTC P0602 will set.
