Hi,

Recently my TC seems to be acting up. When riding the TC light comes on randomly and stays on for 3-5 seconds, ie. not the blinking that occurs when the TC is intervening. At the same time CHEC is showing in the display and the gear indicator is showing "-".

This happens every 15 minutes or so. I have tried, but been unable to reproduce the event.

I have done some testing on gravel, and the TC appears to be working like it should.

Has anyone else had this?

Have you done any work on the bike? Lose cable behind the console? CPU?

Sounds like it could be a bad connection somewhere. Probably not it, but very simple and good place to start - check the battery terminal connections to make sure they're tight. Then maybe start at the dash and work out checking connectors. Should also check ground connections to the frame. Maybe a dealer could read a stored trouble code?

I also thought bad connection. Have had it dynoed and remapped so there is a probable source for the problem. Had it back to the shop today to check the connections they modified (they installed a connector to be able to read/write to the ecu). We (they) did not find any problems. I was standing right next to the mechanic checking the connectors and they looked fine to me too.

I know how to read error codes off the bike. I have not tried yet, and as the error is only occurring a few seconds at the time I doubt there will be anything to read. But i will check it out.

From the manual:

NOTE: When the display indicates “CHEC” in the odometer display area, the gear position indicator does not indicate a number but indicates “–”.
and

When the display indicates “CHEC” in the odometer display area, check the following items; • Make sure that the engine stop switch is in the “RUN” position. • Make sure that the transmission is in neutral or the side stand is fully up. If the display still indicates “CHEC” after checking the above items, inspect the ignition fuse and the connection of the lead wire couplers.
If it didnt happen before the remap but did straight away afterwards, that's got to be your prime suspect. Could the remap have messed with the ignition maybe?

Not sure I would be happy having to add extra connections for the remap, but no I'm no expert, so maybe this is normal. My remap was all done through an existing connector in the tail.

Try with the usual Computer solution first. Disconnect the battery, wait 5 minutes for every thing to discharge, then reconnect.
While there with the battery is disconnected, check the standing voltage as it's always possible that a cell may have an intermittent short internally or a snapped busbar from vibration.
Battery problems explain a lot of strange car and bike issues.

Did the shop leave a cable in your bike for future map/tune updates?

When you say the connections 'looked' good - do you mean aesthetically, or did someone use a meter and jiggle the wires?

Does your setup have an AFR monitor?

Yes, the cable was left in the bike.
They only did a visual inspection of the connectors.
Not sure what you mene by that. The shop did not remove the bikes lambda sensor, as far as I know, but I have no extra AFR monitor.

Thanks, I will try that.

I have never heard of a remap being done through an existing cable in the tail - its usually done by adding in a harness that connects directly to the ECU or by removing the ECU to flash it.

Who did the reflash/what software was used?

I have a Woolich harness and logbox installed on mine. I run with the TC off per Woolich instructions but get the CHEC popping up regularly (like every 15mins). I believe this is to do with the logbox. Part of the harness connects into the service plug so it makes sense to me. If I don't have the log box plugged in, I don't get the CHEC appearing

Checked and they used Woolich.

Tried pulling the logbox off?
There is no logbox connected. I'm going to disconnect the battery this weekend. If that doesen't work the next step will be to reflash with the factory map to eliminate the possibility of programming errrors in the new map.

In that case, my first thought is some learned gear position variables have been cleared. I'm not totally certain how the logic of the traction control functions, but it stands to reason that gear position would be at least a limited input to the feature. Maybe try looking up a suzuki-specific method for getting the bike to re-learn transmission gear selector position. You mentioned that it sometimes displays gear position, but that doesn't necessarily mean that the TC has those variables stored as well.
