Electronically Erasable Programmable Read Only Memory (EEPROM) Programming

  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. To verify proper EEPROM programming, start engine. If engine starts, go to next step. If engine fails to start, ensure all electrical connections on PCM are okay and all fuses are okay. Check Techline for latest software. Once engine is repaired so it will start, go to next step.
  3. 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.
