Powertrain Control Module (PCM)
The PCM is a programmable computer and does not contain a EPROM or calibrator. The PCM contains a Electronically Eraseable Programmable Read Only Memory (EEPROM), which must be programed before being placed in service. The EEPROM can be programed for any engine / transmission combination. PCMs are Sequential Port Fuel Injection (SEFI).
