Electronically Erasable Programmable Read Only Memory (EEPROM) Programming (4.0L)

WARNING: This page does not describe the selected car, but rather 38 other vehicles, including the 1998 Saturn SW2, 1998 Saturn SW1, 1998 Saturn SL2, 1998 Saturn SL1, and 1998 Saturn SL. However, it is still accessible from the selected car via links, so may be relevant.
  1. If Powertrain Control Module (PCM) was replaced, the EEPROM in the PCM must be programmed. If EEPROM is not programmed, a Diagnostic Trouble Code (DTC) will be set in the PCM or PCM may be damaged. Perform EEPROM programming using the Techline equipment manufacturer's instructions and latest software applicable for the vehicle model.
  2. Once EEPROM is programmed, use scan tool to clear DTC P0603 from PCM. Engine oil life interval and transaxle fluid life interval must now be reprogrammed using proper procedure. Turn ignition off. Wait 30 seconds to ensure all memory learn procedures occur.
