    OPERATION

    When the term Electronic Control Module (ECM) is used in this guide it will refer to the engine control computer regardless that it may be a Vehicle Control Module (VCM), Powertrain Control Module (PCM) or Engine Control Module (ECM).
    The Electronic Control Module (ECM) is required to maintain the exhaust emissions at acceptable levels. The module is a small, solid state computer which receives signals from many sources and sensors; it uses these data to make judgments about operating conditions and then control output signals to the fuel and emission systems to match the current requirements.
    Engines coupled to electronically controlled transmissions employ a Powertrain Control Module (PCM) or Vehicle Control Module (VCM) to oversee both engine and transmission operation. The integrated functions of engine and transmission control allow accurate gear selection and improved fuel economy.
    In the event of an ECM failure, the system will default to a pre-programmed set of values. These are compromise values which allow the engine to operate, although at a reduced efficiency. This is variously known as the default, limp-in or back-up mode. Driveability is almost always affected when the ECM enters this mode.


    REMOVAL & INSTALLATION

    See Figures 1 and 2

    5. Remove the ECM.

    To install:
    1. Install the ECM into the bracket.

    I can answer the first question. The year of your car will run without the cataltic converters and not affect the performance or fuel milage. Your ECM is not that sophisticated. You can call a parts store and they can tell you where the ECM is located

    Where is the ECM located


    Hello.

    The ECM is mounted on the right side of the dash above where the passengers feet would be.
    The lower panel will need to be removed to see it.
    Here is the service manual procedure to remove it.
    1. Turn ignition to "OFF".
    2. Disconnect battery ground cable.
    3. Remove right hand hush panel.
    4. Disconnect connectors from the ECM
    5. Remove ECM mounting hardware.
    6. Remove ECM from the passenger compartment.
    7. Remove ECM access cover.
    8. Transfer PROM unit to replacement ECM. Using two fingers, push both retaining clips back away from the PROM. At the same time, grasp it at both ends and lift it up out of the socket. Do not remove the cover of the PROM. Use of unapproved PROM removal methods may cause damage to the PROM or socket.
    9. Remove new ECM from its packaging and check the service number to make sure it is the same as the defective ECM.
    10. Remove access cover.

    Where is the ECM located


    On the 96 Se the computer should be located on the drivers side, behind the fuse panel. Remove the side interior panel, then loosen the bolts that hold the fuse panel so that you can get to the plastic box with a lot of wires hooked up to it. They are snap-fit connectors like the rest of them.
