Hi all, I have an '04 xb12r that has gone through some stuff in the last year. Short version: After putting in new ECM, I'm getting an error 36 - fan to ground short or open. I took apart the front end that I'd taken apart earlier to put in the new ECM and can't seen that I'd pinched anything (I'd checked fuses first, and they were all ok). So then I wanted to see if the fan would come on. After letting the bike sit running for a spell, the fan came on - right at 225 degrees Centigrade. After turning the bike off, the fan still worked. Could the error code be an error? If the fan is working, with the check engine light on - how much should I worry? -Bryan  | ||

Was it a stored error from the previous cycle? I would clear it and see if it comes back. | ||

I've tried clearing it, and it returns. The check engine light comes back on after the engine starts. (On when key in but before hitting starter, then off for a few seconds after bike starts, then back on) | ||

After I replaced my ECM, I had the bike at the dealer to flash the ECM and reset the TPS. My light comes on the same, but they said it wasn't showing a code and didn't know what was causing it. I have been ignoring it, but now you make me want to check for a code. Is there a way to get at the fan ground lead to check if it is a good ground? Might be a real cheap fix. | ||

You're getting a check engine light with no code? The shop manual calls for checking some of the leads on the ECM with some diagnostic tool from the dealer (name slips me right now). (Message edited by hunleycrew on June 10, 2012) | ||

Light on, no code, is a ground problem. On the R, on mine, it was the corroded ground wire on the harness side of the 4 to 3 headlight connector. Have fun, this will take a while if its not that. Don't take it to the shop, you can't afford it (unless, of course, you can). Leave the key in, light on, and wiggle all the wires until the light goes out. | ||

By riding with the ground out, what damage am I doing to the bike? The wiring you're referring to are the harnesses coming out of the ecu plugs? Will I be looking for any wiring outside of the nacelle area? The light you're talking about going out is the engine warning light, right (not the headlamp)? | ||

A bad ground sends confusing signals to ECM. Limit of my electrical knowledge. What I don't know about electricity is shocking. Nope, main harness to headlight assembly. Light is the CEL, yes. Check when CEL is on, is headlight working? | ||

Everything works. Fan comes on. Headlamp works, turn signals work, brakes work, but haven't seen if the brake light comes on - that, I'll check. Brights work. I'm wondering how much is the bike's new personality with the new ecu, or ecmspy is picking up the wrong error code. |
