Electronically Erasable Programmable Read Only Memory (EEPROM) Programming
WARNING: This page does not describe the selected car, but rather 98 other vehicles, including the 2001 Saturn SW2, 2001 Saturn SL2, 2001 Saturn SL1, 2001 Saturn SL, and 2001 Saturn SC2. However, it is still accessible from the selected car via links, so may be relevant.
- The replacement Powertrain Control Module (PCM) comes with the EEPROM already programmed. However, the PCM must be programmed with proper immobilizer signal for anti-theft system before the vehicle will start. See CONTENT THEFT DETERRENT SYSTEMS & IMMOBILIZER .
- Once PCM is programmed, perform powertrain On-Board Diagnostic (OBD) system check. See POWERTRAIN ON-BOARD DIAGNOSTIC (OBD) SYSTEM CHECK in appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE.
