Electronically Erasable Programmable Read Only Memory (EEPROM) Programming

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. 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 appropriate ANTI-THEFT SYSTEM article in ACCESSORIES & EQUIPMENT for programming immobilizer signal.
  2. Once PCM is programmed, perform powertrain On-Board Diagnostic (OBD) system check. See POWERTRAIN ON-BOARD DIAGNOSTIC (OBD) SYSTEM CHECK in the appropriate TESTS W/CODES article in ENGINE PERFORMANCE.
