I recently wrecked and fixed my 08' GSXR-1000. Now the red light is on (NOT blinking) and a "5d" or "Sd" error is blinking. Now, even though it looks like a 5, I think its an S, because I had to replace the steering damper with an after market. The bike rides perfect as it used too, so I dont think its anything else. If it is the steering damper, how do I fix that damn error??? Thank you!!

May be totally off here but I changed the sprockets & chain on my k7 1k and forgot to put back on the little nut that tells the speed and registers mileage. But I was too lazy to pull the clutch cover back off and put it back on right away cause I wanted to play around with my new gearing. When I drove it around without the speedometer nut in the output shaft it wouldn't register speed and the Sd light started flashing. I think it stands for Sd or abreviated for speed sensor. It's the sensor down there that plugs into the clutch cover on my bike. Don't know what kind of bike you have though. Opps, okay, you have the same bike I have! Yeah, my Sd light was flashing too and I just put that nut back on the output shaft and it went back off. Is your speedo and mileage working on your display?

Yeah, Everything is working fine. I never touched the clutch except to put fluid in it. I have no clue what the damn Sd means, I looked all over the manual. YOU THINK THEY WOULD PUT IMPORTANT STUFF LIKE CODES IN THERE!?!

Well if you turn the bike on does the Sd start flashing immediately? Or do you have to drive it a little while then it comes on? If it immediately comes on then shut the bike down and put it in dealer mode. If it throws a C-93 thats 4-108 in the service manual and then you will know if it is the steering damper. C-93 is the steering damper solenoid sensor. If it's not then I'm positive it has something to do with the speed sensor. Maybe not in the sensor itself but in the cluster or in the ECU. Like I said, mine was throwing Sd and I put that nut back on and it went away. It wouldn't throw Sd until I drove it about a quarter mile first though. It didn't come immediately on when I started the bike.
Yeah no they don't put codes in there. Thats the stealerships way of making money. If the bike has been wrecked though it could be many ways the speed code is being thrown. Do I know all those way? No... but maybe somehow that nut inside the cover in there got damaged somehow, but then you shouldn't be registering mph though so I don't know. Just try to pull a code on it by putting it in dealer mode and if you get a C-93 then replace the damper solenoid.

Everyone on gixxer.com is satying its the damper and to unplug, and plug it back in... Im going to try that. I know I snapped off the end of the wire (connector) when I wrecked, so IDK if thats going to mess it up...

hopefully it works, if so let me know. It must be something weird that happened with me then cause when I put my speed nut back on the Sd went off.

If you read your manual, it will say that when "Sd" comes on, you have a problem with your "S"teering "d"amper. So if it's an aftermarket unit, you can't plug it in. But if it's another electronic stock damper, then by all means plug it back in!

SD fault code + no mph/mileage

--------------------------------------------------------------------------------

Hey all,
I am getting a SD light on my 07 1000 which i am assuming is a steering damper issue. On top of that i am not get MPH/mileage. Everything else is working fine such as the tach, gear indicator etc.
Can a damaged steering damper be the cause of no MPH/mileage

I have checked the sensor on the left side near the chain. look fine. checked fuses seems like i have done it all. Anybody else experienced this b4. kinda at a loss right now.


Well I guess this says it all. I would have to see in the manual where it says Sd stands for Steering Damper. I looked at EVERY aspect of my manual and there is nothing there.
Here is an old post of a guy with an Sd code flashing and affirming that he has NO reading on Odo or mph. And like I said I had the EXACT problem and putting the nut back on made the light stop flashing IMMEDIATELY.
Anyway I still could be wrong even with all that said, it wouldn't be the first but it definately would be the freakiest coincidence that my light just went back off putting the nut for the SpeeD sensor back on and Sd flashing with my mph and odo not working and other people on this forum in a forum search experiencing the same exact thing.

No light? No "Sd" code on the dash? Weird.

Check the speed sensor connection to the speedo down the inside of the left framerail, near the transmission. It's a white 3-pin plug coming from the sensor on the housing over the drive sprocket.

You can pull that sensor too and inspect it. Sometimes the sprocket cover gets full of crap from the chain and makes it not work so well.

If you can find no trouble here and the bike runs well (it will run like shit, typically, if the actual sensor to ECM speed signal is lost), you have a failure at the instrument cluster or connections. I'd expect you'd better bring your butt-plug to Suzuki if you have to buy one of those.

Here are some more posts of people experiencing Sd errors and mph/odo not working. The first post goes on to further explain that his Sd code is thrown but its way down in the thread so I didn't copy/paste it.

Here is the other part of the post he wrote...

check the plug on the steering dampener i had the same problem it was broke off. if that is not it take it to a dealership and they can read the code

Two things and two things only cause an Sd code: One is the speed sensor signal is lost, that'll be obvious because you'll have no speedo or odo either. The other is the aforementioned steering damper issues. Both of these are electrical problems. As long as the connections are good, no Sd code, regardless of whatever mechanical faults may also be present.

Thank you for clarifying that the Sd error IS TRIGGERED BY THE SPEED SENSOR!!!!!!!!!!!!!!!!!!!!!!!!! As well the steering damper can cause the code but the SPEED SENSOR does cause an error code and this is no 600 in question, these are 1000's we're talking about here and they are two very different machines. My 1000 manual has no info on that page stating the steering damper as an Sd code.
I think I've posted enough convincing posts of other riders to have proven the point that an Sd code means SPEED SENSOR AND RELATED PARTS LIKE THE SPEED NUT, and in other cases the steering damper.
I don't want to computer warrior with anyone I don't want to be told something I know is right, is wrong though.
We're both correct, and the point is that he probably is having a problem because of his steering damper but until I could find out whether or not the mph was reading on his then I wouldn't have been able to tell him for sure.
I simply posted what experiences I went through and what I did to get the Sd light to go off which was screw the nut back on and the light went out.
But either way before I abandone this post where I was trying to help someone with my experiences I will say to the original poster of this that I found out that if you bridge the Steering Damper wires with a 1watt 20ohm resistor for a 1000 it should turn the light off or you can take a hex head driver and take off the sensor part off the damper itself and plug it into the harness and wrap it in plastic and be done.
Good luck.

For your information, k8 600 DO HAVE AN ELECTRONICALLY CONTROLLED STEERING DAMPER as well. If you read my last post, it even states in the owner's manual that "Sd" stands for a fault with the steering damper, whether it's actually caused by the speed sensor or steering damper. Isn't that what the first guy's question was? :headscrat

I have a k7 1000 and i am getting the "5d" or "Sd" code. I built my own TRE and have it wired to a push button and mounted where the right side seat bolt used to be. The TRE works very well but when I ride for awhile the light comes on (does not blink) and everything seems to work just fine. When the TRE is off I can ride all day long without a single light or code issue. I'm not too worried about it, I was just wondering if anyone knows what it means.

Sd Error

Hi
i had the same problem my self.
The problem was spoted in the wire that goes to the plug of the steering damper. it was cut in two spots. At first i have just saw the first cut, but the problem was still there. so i took the plug from the steering damper out took all the wires to the right site (as you sit in the bike) and i find another cut in the wire. After fixing this problem, everything seem fine, and the indicator "SD" has switched off. Good luck, i hope it was helpfull.

mine did this today, after reading this post i have a broken steering damper wire right at the plug. looks like the harness is a little too short for when the steering is maxed out, ill be extending the wires about 2" and repinning mine to fix this issue.


btw, thanks for the good tech advice guys, it only took me about 3 minutes to find my problem and thats because i had to log in.

I am having a similar problem with my k8 600. It starts up fine and will run for a while then the code pops up and a few min after that the bike just shuts off and wont start. Any ideas? I dont think the steering dampner would shut the bike off.

"chrisblkz" My 09 gsxr600 did that today too????? was riding for a good hr, then solid red light with flashing Sd (where temp gauge is at). rode it for lil bit, then rpm, mph, everything froze. Bike still ran.....so I wasn't to far from home so hurried then bout 2 blocks from when tach freezing, bike shuts off and wouldn't start. So I tried to start it couple of time and no luck. feels like a weak battery when trying too.....So then I had someone help me jump it. Fired right up, tach fully functional.......???????rode it 2 more block to the house, parked it, tried to start it up again.........NOTHING, now i'm pissed.....brand spanking new bike. well not new anymore but has 2200 miles on it now. Any help on this would be helpfull. Thanks
