Hey guys, this is starting to irritate me. Recently my regulator/rectifier died, cooked the battery, got stranded 2 hours from home. Got the new regulator/rectifier in, charging system's sound, new battery in. I am still left with a problem however. My instrument cluster is continuously displaying a dash ( - like that ) in my gear position window, and CHEC in the temperature window. With bike in neutral (green N light comes on), kill switch works properly, kick stand switch works properly. Kick stand up motor will run, kickstand down in gear will kill the motor. Kill switch in the run position motor runs, kill switch in the off position kills the motor or will prevent engine start as expected. Still, no matter what I do I cant get rid of the CHEC in temp display and - in gear position display. Anyone else ever have this problem? Any ideas for me? Thanks for any help. :dunno

Do an ECU swap and see if the problem goes away. If not do a cluster swap and see if that fixes it. It happened at the same time as your rec/reg went south?
Since you popped a rec/reg I would check your stator as well to make sure it's not poo pooed on one of the phases. Not saying that is causing your dash problem.

Tried an ECU swap, no luck. Stator passes the voltage output test, tested that before my reg/rec. I'm leaning toward Gear position sensor, I'm on my second one already, so it's a known weakpoint. It's a 3 wire plug, one of the wires for neutral I believe. Maybe my friend will let me borrow his I-cluster just to make sure. Keep em comin guys
Ok, might have your answer here.

Have a look at the red wire. It is common to all the gears. neutral has its own circuit.
I think you have a bad connection somewhere between the GPS on the red wire siide back to the ECU. Hopefully, fingers crossed, it is not the ECU itself. Which you have already ruled out by doing the swap.
Let us know how it goes.

Yeah, faulty GP sensor is looking more and more like the likely scenario. I do recall it starting to flicker between gears occasionally before the reg/rec going out, this was happening more and more before my first GPS went out. Highly doubting that I will ever buy another Suzuki, this bike has been nothing but a headache since day one when I got it new. From the factory I had the oil leak from the bolts that hold down the output shaft plate, Suzuki's warranty is a total croc. Even if the bike is less than a month old they won't fix anything unless you are paying for it. Wish someone else made an i4 750cc :sad

That wiring digram corroborates some info I received yesterday. John at Jett tuning says he has seen TRE units take out the GP sensor in scenarios such as this. Thank you for your input. Wish I could afford owning an S1000RR, insurance would be ridiculous though being that I am not 25 yet.

I am runing a heal tech x-tre, which locks in the gear signal of your choice without losing your gear indication function on the I-cluster. I don't know what's inside the box, but obviously more electronic trickery than a tre unit that always indicates 5th gear on the I-cluster. When the reg/rec goes out it is possible for the high voltage pulse from the stator to make it through the entire system. Of course this is all speculation till the new GPS shows up and I can verify, but the fact that the reg/rec went out opens a real can of worms as to what actually happened. This whole scenario baffled my friend, a certified Suzuki tech amongst other manufacturers, I really hope the GP sensor is the final solution, I've got a fresh set of power pures sitting on the tire rack laughing at me.

Ok, so here is the latest in my headache of a motorcycle. Got the new GP sensor, plugged in, did not cure the problem. Had my friend come over with his 07 to swap speedometers, mine works fine in his bike, his plugged into my bike, still coming up with the error message. I took electrical contact cleaner to all the connections on the bike with no luck. Still scratching my head. I called suzuki america and of course they directed me to visit the local Suzi dealer... They said an authorized shop would be able to plug the bike into the SDS diagnostic system which I know is a load of crap, the SDS is a glorified multi-meter.
Anyone with a burned out stator ever get this - in the gear position window and CHEC in the temp window? I am not seeing the numbers I expect on the stator test, and I am thinking it is out, but doubting that the stator is giving me this error.

I'm not sure if this will help but this is a copy from page 4-17 of the manual:
“CHEC”: The LCD panel indicates “CHEC” when no communication signal from the ECM is received for 5 seconds.
For Example:
The ignition switch is turned ON, and the engine stop switch is turned OFF. In this case, the speedometer
does not receive any signal from ECM, and the panel indicates “CHEC”.
If CHEC is indicated, the LCD does not indicate the trouble code. It is necessary to check the wiring harness between ECM and speedometer couplers.
The possible cause of this indication is as follows;
Engine stop switch is in OFF position. Side-stand/ignition inter-lock system is not working. Ignition fuse is burnt.
NOTE:
Until starting the engine, the FI light turns ON.
The FI light is also turned ON when engine temperature is high or oil pressure is low.
From the wiring diagram it looks like only a couple of wires go from the speedo to the ecm. Bad connection, damaged wire?

This is easy. Ok, so you did:
1) An ECU swap - same problem.
2) Speedo swap - same problem.
3) GPS change - same problem.
As I said before check the red wire.
A multimeter would help. Find the GPS wire where it enters the ECU plug and check its continuity back to the socket on the mainframe loom for the GPS plug.
I think there is a slide lock that needs to be depressed on the ECU plugs that will allow you to remove the appropriate wire. Or you can put a fine needle in the plug to make electrical contact with it.

Just went out to my bike and tried something.
With kill switch in the "run" position, I turned on the ignition switch. Fuel pump cycled, temperature read "---" (bike is cold) and gear position display showed "0".
With kill switch in the "stop" position, turned on the ignition switch. Fuel pump does not cycle (normal) after about 5 seconds temperature window shows "CHEC" and the gear position display shows "-". So these two indications are tied together.
Wiring problem for sure.

Problem solved, when the stator and reg/rec went out it burned out my timing retard eliminator. Thanks everyone for your input, I'm gonna go tear the canyons a new one as soon as the warrantied TRE shows up.
