    The check engine warning on the dash appears when an active fault is occurring that the EMM knows about. Not all trouble code conditions will trigger the check engine warning.

    The Ficht EMM stores fault codes as they occur. Reading the fault codes reveals all the stored codes, including issues that may have occurred a dozen hours ago, or one minute ago, or still happening right now.

    A useful method is to read all the stored EMM codes. Then erase them. Then see which codes re-occur. And under what conditions (short duration engine start, longer engine run, high throttle run across the water, etc). This tells you which immediate problems need to be corrected and which problems might no longer be happening.

    There are three connectors involved.
    The 12-pin connector unplugged from the back of the dash display.
    The 8-pin connector unplugged from the EMM
    The 3-pin connector unplugged from the TPS on the throttle body.

    A) 12-pin dash connector gets the simple LED+resistor plugged into pins 2 and 4.

    OPTIONAL (Virage and Genesis only) : Also jumper pins 1 and 3.
    This allows the engine to crank while the display is unplugged.


    B) 8-pin EMM connector gets white/red and red/Purple wires jumpered together. This supplies ‘service mode power’ to the EMM.


    C) Unplugged 3-pin TPS connector gets a jumper between the center and red wires.

    Then insert the lanyard and observe the stored codes via the LED blink sequence.

    Either a ‘12 volt’ integrated LED light or a simple bare LED with an inline resistor.

    I typically use a nothing special basic single LED with a 330 ohm resistor soldered in series, as shown in prior photos. That provides about 30 milliamperes of current through the LED.

    You cannot use a high wattage LED as the EMM LED signal driver is not intended to drive a heavy current load.
