Engine Control Module: Description and Operation
EEPROM
DESCRIPTION AND OPERATION
The Electronically Erasable Programmable Read Only Memory (EEPROM) is a permanent memory that is physically soldered within the
Powertrain Control Module (PCM). The EEPROM contains program and calibration information that the PCM needs to control powertrain
operation.
Unlike the Programmable Read Only Memory (PROM) used in past applications, the EEPROM is not replaceable. If the PCM is replaced, the
new PCM will need to be programmed. Equipment containing the correct program and calibration for the vehicle is required to program the PCM.
