COMPUTERIZED ENGINE CONTROLS
ELECTRONICALLY ERASABLE PROGRAMMABLE READ ONLY MEMORY
Electronically Erasable Programmable Read Only Memory
(EEPROM) is a permanent memory that is part of PCM. EEPROM cannot be
replaced. EEPROM contains program and calibration information that PCM
uses to control powertrain. If PCM is replaced, ensure NEW PCM
software/calibration is correct and most recent version for vehicle.
EEPROM must be programmed when NEW PCM is installed. Program EEPROM
using latest software for that specific vehicle.
POWERTRAIN CONTROL MODULE
CAUTION: Electronic components used in control systems are designed to
carry very low voltages. As little as a 30-volt charge
created by static electricity can cause a total or degrading
failure in PCM or other electronic components containing
integrated circuits. Before servicing Powertrain Control
Module (PCM), technician must ground himself and the work
area to discharge static electricity.
CAUTION: Do not remove part from packaging until ready to install.
Ground any static-proof package before opening. Do not touch
electrical terminals of components unless properly grounded.
Do not lay electrical components on car seat, carpeting or
dashboard. Use electrostatic protection mat and ground strap
whenever possible.
NOTE:
Before replacing PCM, carefully inspect all wiring and
control components. Failure to test for short circuits may
result in repeated PCM failure due to shorts. To prevent
internal damage to PCM, ensure ignition is off when
connecting or disconnecting PCM harness connectors or any
electrical components.
