I accidentally made short circuit from my xb9 battery to frame just some minute before starting, and after warming engine a little (no signs of failures) I started. 10 meters and engine light flashed while fan started running and engine stopped. I checked fuses and rel่ (the other black box), everything was ok but I turn the key on the fan starts running and engine light flashes. In another post chainsaw (thank you very much!) gave me trouble codes but when I tried to read, turning on the key is causing the fuel pump to start and stop unitl I switch off and engine light flashes all the time with no code. I asked the only one dealer open in the north of Italy (350 km.) but they say they're so busy they' ll come to pick my bike at the end of the next week... so I have all the time to try to find by myself what is wrong, order parts from Dave and repair before they arrive. Can anyone help me? thank you.

Trying to have trouble codes i've noticed that ecm side with grey connector become very hot with key on and if I insert but not lock grey connector I can read some error code I read before, because fuel pump stops:
11, 13, 33, 34 then, every time, fuel pump starts and engine light blinks at higher speed
What the **** is that?

Another update
As posted in "What is error code #6". I probably was wrong. Please read the other thread and give me some suggestion.
Sorry again...

My guess is that you need a new battery. If you short from the battery to the frame, the only thing that you may hurt is the battery. If the battery is more than two years old, its probably time anyway.

Do you have a way of checking how many volts (need a voltage tester) the battery is putting out of the bike when the bike is sitting and when you turn over the key. The battery is small and I don't thing it could take a cross over like a car battery.

If you have a friend with a motorcycle you can try just putting in his battery and see if that fixes it.

But it sounds like a battery that doesn't have enough juice to run.

Do you have a battery charger that you can try and charge the battery?

I will look over the codes in the Buell book.

Code 11 Throttle position sensor
Code 13 Oxygen Sensor
Code 33 Fuel Pump
Code 34? Doesn't exist
Maybe code 24 Front Igition coil
Maybe code 44 Bank angle Sensor


But, again I am thinking the battery doesn't have enough juice to run. Try charging the battery.

To clear the codes:
Start the motorcycle
Let run for at least 30 seconds
Turn the engine off.
(This is from the Book)

If this doesn't work. Pull off the battery cables, put the key in and turn the key to start and hold on the starter button for 60 seconds to drain all the power out of the system(again with both the positive and negative battery cables off the battery and not touching the bike in anyway.

Thanks everybody, I connected battery to charger one hour ago and even if it's not colpletely charged, now fuel pump is ok, but now fan runs continously while engine light shows every code from 11 to 36. after 36 I switched off to avoid battery ends another time. Tomorrow morning I'll clean codes and try with another battery.

If the connector is getting really hot that is a bad sign, sounds like a short. Extreme heat is caused by too much current traveling through wires.

Check the main fuse under the seat. Also unplug and then plug back in the diodes. I shorted mine once while working near the starter with the battery still connected. Mine started right up after unplugging and then plugging the diodes back in.

check the ground kabel on the frame behied the fairing ( 2 little black cables )
and the ground ( small wire ) next to the battery , check the main fuse as well next to the battery it's covert by a black plastic cover,


iff it aint that, i think your ecm is fryed

you are in error: running the engine for 30 seconds will NOT clear trouble codes.
starting and running the engine for 30 seconds, shutting it off and repeating the cycle 30 times will supposedly erase the codes, but if you do that you will most likely get a new code for a low battery voltage, besides which the process would take over 15 minutes, and probably heat up the starter a bit more than really necessary.
my advice is to get a NEW fully charged battery, install the battery, and go ride, preferably a long ride out of town. good luck, and enjoy the bike. dean

There is no reason to clear trouble codes, they're just stored, eventually they go away, unless the fault remains...historic faults do not affect performance.

The grey connector should not get hot, it only deals with very low current sensors except for fan control. You should never turn the key on with a connector half-plugged in. Remove both connectors, inspect for corrosion or anything wrong, and reinsert them and make sure they are fully home and locked.

If the grey connector is still getting warm feel with your fingers to find out what coloured wires are getting warm, this may give us a clue to the probs.

From the manual, when you first switch on the key (with the run switch also on) the CE light should come on for 4 seconds and then go out. If it then comes on again and stays on more than 8 seconds then a current fault exists.

Also from the manual, if the CE light blinks then it indicates an overheated motor. With your symptoms of flashing CE light and fan running on a cold motor, it is possible the ecm thinks the motor is too hot. I would be checking the cyl head temp sensor wire for faults (the pink/yellow wire from the grey ecm connector).

Other than that I think you may have fried the ecm, but I can't see how shorting the batt would neccessarily do that. Good luck. Just throwing in a few suggestions since you have some time. If it were me I would give the batt a good charge, turn on the key, if the CE light starts blinking after a while (with engine started or not) and fan on, go straight for the cyl head temp wire.
