Electronically Erasable Programmable Read Only Memory (EEPROM) Programming

WARNING: This page does not describe the selected car, but rather 67 other vehicles, including the 2000 Saturn SW2, 2000 Saturn SL2, 2000 Saturn SL1, 2000 Saturn SL, and 2000 Saturn SC2. However, it is still accessible from the selected car via links, so may be relevant.

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.
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.
Once EEPROM is reprogrammed, perform powertrain On-Board Diagnostic (OBD) system check. See POWERTRAIN ON-BOARD DIAGNOSTIC (OBD) SYSTEM CHECK in appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE. Ensure engine is idling for one minute before checking for DTCs when performing powertrain OBD system check. Also after EEPROM is reprogrammed, the password learn procedure for the anti-theft system must be performed. See BCM/PASS-KEY RELEARN PROCEDURE FOR ANTI-THEFT SYSTEM.

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.
