Service and Repair
Fuel Module (Located Above Blower Motor Assembly)
Replacement of the Powertrain Control Module (PCM) consists of a service controller, without a PROM (MEM-CAL).
If the diagnostic procedures require the PCM to be replaced, the PCM, PROM (MEM-CAL) should be checked for the correct part number. If they are correct, remove the PROM (MEM-CAL), and install them in the control module. The control module will not contain a PROM (MEM-CAL).
IMPORTANT: When replacing a production PCM with a control module, transfer the broadcast code and production PCM part number to the control module label. Do not record information on the access cover.
NOTE: The ignition must be "OFF," and disconnect negative battery cable when disconnecting or reconnecting the PCM connector, to prevent internal damage to the PCM.
NOTE: To prevent possible Electrostatic Discharge damage to the PCM, Do Not touch the connector pins or soldered components on the circuit board.
