    Arrow How to Reset/Clear Ficht EMM engine service/trouble codes on Genesis, Virage, MSX 140

    hi everyone from the UK

    just found this site the other day and it's got to be the best PWC site in the web

    i hope you can help as i'm having problems clearing the engine codes on my 2002 genesis i

    the codes are
    17 ALTERNATOR VOLTAGE BELOW EXPECTED RANGE
    41 COOLANT TEMPERATURE SENSOR CIRCUIT MALFUNCTION
    42 COOLANT TEMPERATURE SENSOR BELOW EXPECTED RANGE
    81 #1 (MAG) IGNITION COIL OPEN PRIMARY
    82 #3 (PTO) IGNITION COIL OPEN PRIMARY
    83 #2 (CENTER) IGNITION COIL OPEN PRIMARY

    i bought the ski with a seized engine that was causes by the fuel pump failing
    also found the fuel reg in the bottom with the pump
    so i have fitted a good engine and a new pump and fix the reg in place with split pin (thanks to K447)
    also followed the (How to read Polaris Ficht EMM trouble codes without special software or a computer)
    to get the codes
    but i can't seem to clear the codes
    i have tried erase the codes manually by unplugging the TPS and and pluging back in over the 5 seconds

    am i doing something wrong?

    i think the codes are old codes from when the engine went into meltdown but want to be sure before i take it on the water

    also i have one connector that i cant find where it goes




    hope you guy's can help as i would like to get some time out on it before the end of the season
    thanks
    phil

    Welcome

    To clear the codes, you can use EITHER the same jumper that you used to activate the code reading, OR you can use the actual TPS.


    Using the jumper, you disconnect the jumper from the TPS connector (either or both pins, just don't get confused about which pin pair you are shorting with the jumper). You do NOT use the black TPS wire at all during this process.
    Update: Using the jumper wire method does not work consistently enough.
    A more reliable method is using a switch, as documented here
    .

    Let me know how this works for you, and which method you used.

    The EMM code reset pattern goes as follows;

    Leave the lanyard in place, and EMM Service Power jumper in place.


    Update: Do not use the wire jumper method
    Using the TPS jumper method
    - Disconnect TPS jumper and wait more than 5 seconds

    Using a smooth cadence (maybe a second in each position)

    - Reconnect jumper (1st time)
    LED code light will turn OFF
    - Disconnect jumper
    LED code light will turn ON

    - Reconnect jumper (2nd)
    - Disconnect jumper

    - Reconnect jumper (3rd)
    - Disconnect jumper

    - Reconnect jumper (4th)
    - Disconnect jumper

    - Reconnect jumper (5th)
    - Disconnect jumper

    LED will go out, indicating that codes will be cleared, and no new codes have immediately occurred, if there are no Hard Codes. If there are Hard Codes (meaning the problem is still happening right now), the light will turn back on.

    Using the TPS method (Pending review for accuracy)
    Note: TPS must be removed from the throttle body, or use a spare TPS

    - Plug TPS into TPS connector (if it wasn't already)

    Using a smooth cadence (maybe a second in each position)

    - Rotate TPS to minimum throttle stop, and hold there for more than 5 seconds
    LED light should stay ON

    - Rotate TPS to full throttle stop (maximum rotation)
    LED code light will turn OFF

    - Rotate TPS to minimum throttle stop
    LED code light will turn ON

    - Do the TPS full rotation to maximum, then back to minimum, four more times

    Update: This may be inaccurate regarding whether the LED goes out or not
    LED will go out, indicating that codes will be cleared, and no new codes have immediately occurred, if there are no Hard Codes. If there are Hard Codes (meaning the problem is still happening right now), the light will turn back on.

    Unplug tether from switch.
    Codes should now be erased.

    Check again for stored codes without starting the engine. This will tell you if there are hard codes.

    To check for recurring codes, run engine. Then read codes again.

    Note: the EMM may automatically clear old service codes after 15 running hours, if the same code has not re-occurred during that time.

    That looks like the water temp or air temp sensor connector.

    The air temp sensor connection is under the base plate of the flame arrestor. Hard to see under there, it has Black and Pink/Blue wires.

    There is a small rubbery bump inside the flame arrestor base, and the temp sensor is under that.

    While you are in there, make sure the plastic webs from the flame arrestor cover have been trimmed back, so they don't cut into the top of the temp sensor.

    Also, check the ohms of the air temp sensor and water temp sensors. Should be close to 1,000 ohms, give or take.

    The Water temp sensor is mounted on the exhaust side of the engine, and has Black and Pink/Black wires. Look for the matching connector around the exhaust pipes. Item 4 in this diagram;

    thanks for the advice

    i have been using the tps jumper method but with no success will try it again tonight

    as for the connector i think i may be the air temp sensor as the one in the exhaust is connected

    will check it out tonight

    cheers

    Hi and many tnx to K447 code reading worked for Genesis and Virage 800 I perfectly using LED to clear codes worked only option with TPS plugged in and plugged out in the open position (maximum rotation).

    Can u help me in this to big for me problems got to Polaris 1. Virage 800 I 2. Genesis. after done with code reading got this codes:

    Genesis does not start at all only some times wonts to start but its only clumps bangs it seems to me that only 2 from 3 cylinder tries to fire.

    Virage one after reseting codes started ok but after couple of days it does not starting . no idea. PLS. HELP.

    these groups of codes are familiar..the ecm has failed ( by some twist of fate I have 3 maybe 4 fi polaris skis in the shop now, all with an ecm problem). Pull it and send it out to repair...about half the cost of a new and somewhat unobtainable ecu..and besides that..with a new ecu you need to get the fuel injector maps in place, which requires some more trickery. Let's take this over to another thread..this isn't the right place to start up something new.

    2000 Polaris Genesis Clearing codes

    Hi I have a 200 Polaris Genesis here and have used your method to retrieve the trouble codes, They are as follows 12,17,39,81,82,83, I have tried to clear these codes using your method, When using your method you state to remove TPS jumper leaving EEM jumper and MFI LED, and lanyard in place so I am assuming that when clearing codes you are unplugging the TPS jumper when the EMM is in code reading mode is this right? I have also tried unplugging TPS jumper with the lanyard off then plugging lanyard back in, This method produces the LED to respond somewhat like you ask But at the end of the 5 on off on offs and the TPS jumper ending off the LED is off and does nothing, If I plug the TPS jumper in the light stays on and nothing else Which I am assuming that I have not entered the reset process right, Please help
    PS Ski runs sitting out of the water just has check engine light on with these codes

    Welcome

    Are you using the jumper method or the TPS rotation method?

    One second pauses between each change (roughly)?

    Unplugging lanyard at end of process?

    If the Check Engine message is appearing then one or more reported problems is still happening, right then. You cannot clear a 'hard code' that is still occurring.

    Another possibility is that the EMM needs repair.

    Emm Clearing codes

    Yes, I am using the jumper wire on the TPS, One secound intervals, The light never goes out at the end so not sure when to take the lanyard off?

    Whom would I send the EMM too? To have it repaired?
