Is there a way of getting error codes without having a code reader? For example, certain number of blinks from one of the lights on the dash panel, etc. I know there are some automobiles that allow you to do that by counting the number of flashes. | ||

Easy. 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. There is no way to clear trouble codes using this method. The only way to clear codes without hooking the bike up to a computer is to take the bike through 50 start and run cycles (start engine, run for at least 30 seconds, shut it off). The trouble codes are as follows: 11 Throttle position sensor 13 Oxygen sensor 14 Engine temperature sensor 15 Intake air temperature sensor 16 Battery voltage 21 Interactive muffler control (XB12 only) 23 Front fuell injector 24 Front ignition coil 25 Rear ignition coil 32 Rear fuell injector 33 Fuell pump 35 Tachometer 36 Cooling fan 44 Bank angle sensor 52, 53, 54, 55 ECM failure 56 Cam sync failure Hope this helps...

pins 2 and 4 both in the lower right corner??? can the ecm be reset by disconnecting the battery for a few minute to clear any codes?? as in most autos??? (Message edited by sleez on September 14, 2005) | ||

Pin numbers are printed on the backside of the DataLink. | ||

Sleez -- thanks for the heads up on my brain fart. I fixed the post. I originally had diagrammed the positions, but the spacing is compressed when the text posts, so the diagram was unreadable. As far as clearign the ECM by disconnecting the battery -- don't know if that'll work or not -- just reporting what the shop manual states... Steve. | ||

The ECU will not reset when you disconnect the battery. | ||

Thanks. I'm going to try that when I get home. | ||

OK. Question. Looked at the service manual and it indicates that if you have the stop switch set to run and turn it on that after the check engine light turns off, it will come back on in 4 seconds and stay on for 8 seconds to indicate a new code. Will this always be the case? Is there any point in bridging the pins. Should I maybe run it for a bit, turn it off, then turn it back on again to see if it tracks any codes. According to the manual, there isn't even a stored code of any king. | ||

I tried using the jumper wire on terminal 1 and 2 to read trouble codes from my 2009 Ulysses XB12X via the CEL and the CEL did not flash any codes at all. It did not flash anything. I am curious does anyone know if the DDFI 3 Electronic Fuel Injection ECM for 2008 to 2010 provide codes via the jumper wire option, or does the jumper wire option only work on earlier model Buells 2003 to 2007 (DDFI 1 or 2 I think)? | ||

It works on all XBs regardless of year. Either your ECM isn't getting power or you got the wrong pins. Take a look at this post, it has the pins numbered and more details on the codes: http://www.badweatherbikers.com/cgibin/discus/show .cgi?tpc=142838&post=2360318#POST2360318 | ||

Thanks Froggy and Xtrmbkr for the hints and reference. I was able to get codes this attempt. In my initial attempts I only turned the key to on, and failed to turn the kill switch from "kill" to "ON". Code = 36 Cooling fan. I ran the bike a bit and warmed her up and sure enough, no cooling fan running. Surprising quiet without that crazy fan. - Marc |
