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. Once EEPROM is reprogrammed, the Crankshaft Position (CKP) sensor variation learn procedure must be performed using proper procedure. See CRANKSHAFT POSITION (CKP) SENSOR VARIATION LEARN PROCEDURE.
NOTE: Password must be learned when Passlock(TM) sensor, BCM or PCM is replaced. BCM must be programmed with proper RPO configurations before performing relearn procedures. If PCM is replaced, after programming, PCM will immediately learn the first password it receives. If password needs to be changed, learn procedure will need to be performed.
