    Default FI Light and C00

    I just picked up a 2008 M109R today with 2600 miles. It has the Cobra swept exhaust with a Cobra FI2000 tuner. The FI light is lit, but when I checked the codes, it was clear. What next? Thanks in advance.

    Possibly the exhaust servo is disconnected or taken off and there was no Exhaust Servo Eliminator installed.

    If the FI light is on try starting the bike and then installing the jumper and see if it shows you the actual fault code.

    If it does not then only turn off the red kill switch and not the key and see if it then gives you the fault code.

    Each time you turn off the key it resets the fault codes so the FI light must be illuminated when you try to pull the code.

    Got a code C46. Servo, I'm assuming?

    Will removing the #7 pin from the ecu clear the code?

    Yes it will stop the FI light from coming on due to this fault. (Not 100% on the terminal designation though so double check that)

    Or you can put a ESE in place of the OEM servo module.

    Ok. Thanks BCS. I'll double check the pin, and try that.
