C-light Failure XC-2 Mapping

Post by TCC » Thu Nov 14, 2019 12:17 pm

Hi guys,

I have a 2017 1290 Super Duke GT. Bought it about 3 months ago and don't think the cornering lights ever worked. Recently had it in the dealer for a couple of minor recalls. They hooked it up to KTMs XC-2 Diagnostic Tool and found five outstanding updates so they went ahead and updated the ECU, MCU and other controllers as required.

Unlike the XC-1 the XC-2 doesn't allow any mapping choices. It simply references the VIN and allocates the current map(s) for that vehicle. They couldn't even tell me the map number. It has certainly improved the fueling around 2-3000rpm as the bike is much happier running around town in the higher gears at these low(ish) revs so that's all good.

However, I now have C-light Failure' coming up in the left hand screen. I've tried every combination of DRL/low beam on/off and the c-light test does not turn on the cornering lights. It runs through the test on the screen but the lights don't come on. I can't imagine both cornering lights have failed (heck there are 3 LEDs in each unit). The indicators work fine. The mechanic said it might be the 'Cornering Light Control Unit', the one mounted on the left hand side of the radiator just underneath the tank. He didn't have another one to swop it out with to check and at A$600 retail I was in no rush to have him order one in.

Has anyone on here had trouble with the cornering lights and if so do you mind sharing your experience. The only mention of it I can find on line is in a bike review at launch. The test bike suffered a glitch in the cornering light system causing it to fail. No further comment was given.

Check that the C-lights have been plugged in behind the tank spoilers....... I have made that mistake when putting my tank back on (forgot to reconnect the C-light leads)...... read up how to unscrew and remove the spoilers - it's a bit of a fiddle (don't want to overstress or break any plastic lugs), but is easy enough if you just take your time and whisper sweet nothing's to your GT....... ;)

Or take it back and complain and ask the dealer to check they have connected the plugs.

Hi Aussie Dave,

Yes, the cornering light connectors are plugged in. That's why I mentioned the indicators are working fine, it's just one connector (unlike the Super Adventure S that has separate connectors for the indicators and the cornering lights). I've also checked and double checked the Cornering Lights Control Unit connector is fully home.

As you say unscrewing and removing the tank spoilers to get to them is a bit of a faff but I've done it a few times now and have it down pat.

If I meet another SDGT rider I might see if they'll let me try their control unit to see if that's the problem.

Taking it back to the dealer is not something I'm inclined to do. In fact this is the first time I've taken a bike to a dealer in over 40 years. And I only did it this time because neither TuneBOY or TuneECU can handle the KTMs canbus system and there doesn't seem to be a library of KTM canbus tunes available anywhere (I believe OpenFlash in California is building up it's library but it's still early days). I'm waiting on delivery of a diagnostic port adapter for the KTM so I can try some other diagnostic software and even some simple scan tools.

Thanks for your interest.

Het TCC. In the Settings mode, enter then scroll down till you come across Cornering light test left, click and look to set test being done on corner light, it lights up all three in order, then scroll down to cornering light right, click then check to see light lit up. then exit via the return button.

I also understand with sme map updates this fault has appeared. Some times fault codes go away after a few start up ride cycles. Good luck.

Cheers TCC...... I see where I went off the rails..... :lol: ..... and i was thinking the indicators would be the test to confirm connections.

It reads like KTM may have installed the 19 ECU software (?) - I had that done in June and it fixed the weak rebound damping and updated some engine maps and made the dynamic suspension response faster/better - have this "upgrade" done if it hasn't been installed (it was an owner request upgrade, and didn't list on KTM's service screens as an 'update' item.... but by now I think all KTM tech's probably know about it and might install it by default).

If they didn't install it correctly you may have lost some settings - some guys had their quick shifter's disabled/de-calibrated - so it's worth asking if the download was done, and if it installed correctly. There can be issues caused by software incompatibility after partial update's are installed, as explained by my KTM tech last year when I showed some interest..... enough for me to realize it's something that it was not straight forward and needed to be carefully completed.

PS Maybe post on the busier 'KTM Forum' site..... there are guys on there that have over 40k kms up (one has 100,000kms) on SDGT's.

Pps Just spotted DaveNZ's second post (thought it was a duplicate... but it has an extra line). It is correct that after 3 re-starts some error codes go away (if they were phantom faults) but your C-lights aren't working so there must be a bent pin in a connector or a controller fault or a software corruption issue..... or ????

Hi Again,

I just asked this poster for more info. He suffered the same error after a software update to v3.34 and that's the version that shows on my cluster. Might be worth visiting the dealer again to see if they can go back to an earlier version. I'm not confident though.

Good idea TCC...... did you send a PM as well?

This forum had a couple of issues earlier in the year, and may have lost a few contributors due to being locked out or very slow navigation..... Dewayne may not be a regular so a PM might alert him to reconnect.
