Had a CEL, but it went away............

[ny_driver]

Came on after I left my buddys place today. Stayed on for the 20 miles home and it's gone when I start it up again. Thought maybe oil but it looks plentiful.

Going back out.....any ideas?

Pull your code and see what it was?

 

[Miami78]

Just in case, here's how:

With everything off open your diagnostic port (lightning's will be under the seat/bolts in the front fairing). Look into the port and you will see 4 wire ends. Turn it so the little lock part is at your 12 o'clock position, then use something to jump the two wires on the right (screwdriver usually works best, but anything metal should be fine). With the wires jumped turn on your key and kill switch (but do not start the bike). Your CEL should come on, then flash rapidly about 8 times, pause, then flash slowly for the first digit of the code (the number of flashes is the first number of the code), pause 2 seconds, then slowly for the second digit of the code (again, number of flashes is the second number of the code). If there is a second code it will pause again, then do the same for the second code...when it gets to the last code it will just keep repeating them till you turn the bike back off.

Here's the list of trouble codes...

CEL codes:
11-TPS
13- O2 sensor
14-ET (engine temp)
15-air intake temp
16-battery voltage
21-exhaust actuator
23-front injector
24-front coil
25-rear 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

Could it be the heat.

 

[ny_driver]

I tried to short out the pins and check the code, but nothing came up and the CEL was gone.
Maybe didn't do it right?
Shorted pins 1&2 and turned the key.
Nothing but odometer.

Just wrapped the header yesterday. It was siting in the hot sun awhile befor I took off from my friends.

Maybe it's just bitching because I was over there test-driving a Harley.

 

[Miami78]

After you turned your key on did you turn your kill switch on? It should store a code for 50 on/off cycles.

 

[ny_driver]

The code was 16 - battery voltage......and then it repeated 16 so I think that's the only one.

Bike starts fine so I don't know what that's about.

 

[Miami78]

That's the code that came up both times my stator and voltage regulator were going out. Both times also happened about a week after I accidentally killed my battery by leaving my lights on at work. Have you done anything related to your battery recently?

 

[ny_driver]

My battery has stayed charged since I got the bike.
And I haven't done anything relating to the battery besides turn the key on and off.

 

[Miami78]

Weird. Hopefully it was nothing, Wouldn't hurt to check your battery terminal connections, if you find that your battery stops getting a charge while riding its likely the stator is to blame.

 

[freak2180]

OK for the 3rd time Im trying to post this so lets see if it sticks this time.......


Mine has done this to me also. IT was from jackrabbit starting the bike. Once the bike was shut off it went away. You can rid yourself of the light while riding but that requires going to neutral and killing the bike then restarting.

 

[ny_driver]

Yes, hopefully nothing.

Fortunately mine only came on the 1 time(so far) for about 20 miles then it was gone next time I started the bike.
I don't think I've done any jackrabbit starts.

If the Cel came on then it Will come back on again! Now on 08+ bikes it will most likely be the regulator or stator.If the Stator is going out then a couple of tests will tell you what is needed to keep you riding.
Check Stevenc150 posting list he put together of many Correct ways to Test, he has put together mine there as well and done correctly will help you get to the problem for the System on your bike.
Just look under some of the listings there and this way you can be sure.
The older bikes pre 07/ buells had some issues with the Regulators connector/ 77/ I believe and make sure to check it for burnt terminals so you can replace it .It is an inexpensive kit and easy to do.
American Sportbike .com OR a Buell Friendly dealer will have what you need.
Load test the battery out of the bike at an auto parts store usually that is free. post up with your findings before you are sidelined and check her out to keep riding.
Never jump start the bike with a diesel or auto running the battery is only 200/ccamps or so and can damage your electrical(Costly), If you ever need to jump start the bike then make sure the vehicle has ONLY one battery in it, AND not running while you get it started, unless you want to be spending some serious cash on and ECM and some new harness wiring. Recheck your work and post up here if need be, there is plenty of help here good luck. Welcome to the forum.*Jimi

 

[freak2180]

If the Cel came on then it Will come back on again!

I beg to differ. In the case of my bike It has never come back on since I found out what I did to cause it to come on.

 

[ny_driver]

Thanks for all the helpful information guys![up]
I should have some time very soon to do some testing, and get my battery checked out.

 

[ny_driver]

I took the battery to advance auto and they don't do a load test anymore. They ran their tests and the battery is good @ 12.57v and it meets or exceeds required standards according to the print out.

Well his problem is possibly different from yours,Sometimes people working on their bikes can OPPs it up and make the cel come on due to other issues. Now if he has a charging problem then the cel will eventually come back on.
Unless the light burns out on the cel itself, Very Rare!.Then the bike will just die out and not start. The Cel light coming on Leting the rider know something needs to be checked. Usuallly that model Machine and several other years previous had some problems with charging and Wiring issues.
Regulator AND the Regulator plugs connectors and the Regulator itself. So as I always welcome a difference of opinion yours is welcome also and possibly incorrect for this type of poblem on this machine.
Can't always compare every Machine on all Diagnouss' simply due to so many Simular areas can cause a problem turning on the cel or flashing and so on. That Said I'm glad that in [your case] of what was wrong with your Buell is/ and has been corrected.If needed look up testing in the manuals here on the forum. Some of the manuals will still pertain the same knowledge base as simular and some of the Newer models like 08+ Buells will have some differsnces.Ride Safe.*Jimi
