Electronically Erasable Programmable Read Only Memory (EEPROM) Programming (3.8L)

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.
  2. Ensure battery is fully charged. Ensure cable is properly connected on Data Link Connector (DLC). Turn ignition on. Perform EEPROM programming using the Techline equipment manufacturer's instructions and latest software applicable for the vehicle model.
    NOTE: If EEPROM programming fails, ensure all electrical connections on PCM are okay. Check Techline for latest software. If EEPROM programming still fails, replace PCM.
  3. Once EEPROM is reprogrammed, the Crankshaft Position (CKP) sensor variation learn procedure must be performed using proper procedure.
