Preparatory Instructions

The installation of the updated EPROM into the engine control module is a simple procedure.

However, before beginning the EPROM exchange, the following conditions must be provided and the designated tools must be used.

ENVIRONMENT

The work area where the EPROM is exchanged must be free of excessive dust and aggressive chemicals or vapors. A small uncarpeted office within the dealership is recommended. Since low atmospheric humidity promotes static electricity, an evaporating bowl of water can be used to raise the humidity level of the work area.

EQUIPMENT

Screwdrivers (blade type) are only used to open and close the engine control module. The EPROM is exchanged using an IC extractor/inserter set. Tool sets can be obtained locally (Radio Shack, Archer # 276-1581).

STATIC ELECTRICITY

The engine control module can be damaged and rendered unusable by static electrical discharge. For this reason the 3M static protection kit (or equivalent) must be used during the entire EPROM exchange procedure. See S.I. 04 30 87 (1546) for complete details.

EPROM STORAGE

Replacement EPROMs must be stored in the original shipment containers. The label in the center of the EPROM must never be removed.
