Started a week ago, about a minute or two into the ride it would come on and then go off. Today, the engine started missing the occasional beat and eventually the fuel pump light glowed a steady red. Made it home. Ideas? | ||

There is no fuel pump light. I think you're talking about the engine fault light. You can read the trouble codes without any equipment by shorting two wires. The info on how to do this and how to decode the error messages is all in the knowlege vault. | ||

Mil, you ride a Uly dude! your on your own, enjoy the visit to HD  | ||

Unless of course you now have two, or re-gressed to a tuber(the thread said 99X1)in which case,as Nate said, it's your ck engine light or the fuel low "idiot light"I can say idiot because I was one of those who saw that light come on about 2miles before the bike died...outa gas. Fortunately the X1 is very easy to push. I would still investigate fuel filters feed system and anything related...or be ready to push. | ||

hehe, i learned we had VERY short amount of time after our fuel level light (the yellow light) came on. i ran outta gas on an exit ramp.. uphill push in 115 degree weather. terrible.. anyways, the red light is the engine fault code light... the yellow light is the low fuel level light... which one is lighting up? | ||

Fun did the later versions of ddfi do away with the short 2 pins in the data plug to get the codes via the CEL ? I have see plugs for the Fuel Frames on Ebay | ||

I do have a Uly...and sleeping next to it in the Garage is a 99 X1 lightning...the light, after further research, is the red engine fault light and I found the information about retriving codes...but looking under the seat, I can't see a data plug with shortable pins... | ||

Old mil, Right side of the head tube behind front fork. SteveH | ||

Ah thanks! Found it there...will let you know what I find. | ||

The mystery deepens... Followed these instructions: BUELL ECM First thing to do is locate your diagnostic test plug under the seat. It's an empty four pin connector. If you're looking at it with the pins facing you and the locking tab at the 12:00 position, the pins are numbered as follows: Pin 1 -- upper right corner Pin 2 -- lower right corner Pin 3 -- lower left corner Pin 4 -- upper left corner With the ignition switch off, install a jumper wire across pins 1 and 2 in the diagnostic plug. Turn the ignition switch to the ON position and wait approximately 8 seconds for the check engine light to start flashing. All trouble codes are sent out as a series of flashes. To rettrieve the first digit of the code, simply observe the number of times the lamp flashes. The transmission of a trouble code is always preceeded by six rapid flashes (about 3 per second). This transmission is followed by a 2 second pause in which the lamp is off. The lamp will then flash one or more times to indicate the first digit of the trouble code. The length of time that the lamp will be either on or off when indicating a trouble code is about 1 second in duration. Following the transmission of the first digit in the trouble code, there will be another two second pause before the second digit is transmitted. After the second digit is transmitted, there will be another 2 second pause. After the pause comes another intermission (six rapid flashes) after which the next stored code is transmitted in the same manner. Once all the trouble codes have been displayed, the sequence will repeat. If all you observe is the rapid flashing, then no trouble codes have been stored. When done, turn the ignition key off and remove the jumper wire. Connect the jumper to the #1 and #2 terminals on the data link (marked on the back). code 11: TPS 13: O2 sensor 14: Engine temp sensor 15: IAT sensor 16: Battery Voltage 23: Front injector 24: Front ignition coil 25: Rear ignition coil 32: rear injector 33: Fuel pump 35: Tach 36: Fan 44: Bank Angle sensor 52,53,54,55: ECM failure 56: Cam sync failure. I've tried jumpering the pins with everything from a jumper wire to a paper clip to a pair of tweezers. Nothing seems to get the trouble codes flashing. Cooked ECM? When you start the bike, it runs very poorly, like it's firing on one cylinder. | ||

Perhaps the thing to do here is to unplug that large connecor on the computer and examine it for corrosion or contamination? | ||

Guess now is the time to recommend PREVENTIVE MAINTENANCE ... Un-plug your electrical connectors, check and put in electrical grease ... This prevents HIGH RESISTANCE(acts like an open) connections due to corrosion ... Tie wrap(buy these at Home Depot)all your wiring so it is not doing the WIGGLE TEST while you are riding ... These two things cut down/prevent the mysterious electrical problems ... As we have enough trouble with electrical sensors going bad ... | ||

OM the connection IIRC must be maintained to be active for codes, the "computer" can be fine and a sensor can be out of range usualy a bad ecm does not come and go its just dead ( I am not saying that it absolutly can not be bad just not likely ) Symptoms, runs poorly like on one cylinder, plugs?, wires, condition of harness & connectors, excessive fuel smell? plugs white? My experience random fault lights cylinder head temp sender, key switch, kick stand switch. | ||

I had the engine light come on a few weeks ago like that. My X-1 still ran fine for a while. It ended up being the voltage regulator. | ||

Old_Mil, The instructions for jumping the the pins in the data connector to access the trouble code is accurate but not complete. Jumper the pins, turn key on, flip the ignition toggle switch on, BUT DON'T HIT THE STARTER SWITCH. The check engine light will come on and the fuel pump will cycle as in a normal start-up, then the check engine light will start to cycle through the diagnostic codes as you described. Now excuse me will I go back to the knowledge vault to try and find a cross reference for the X1 O2 sensor. |
