ABS lights

Recommended Posts

Super Sabre

Hey guy's' I have a 2000 K1200 LT that runs great but just recently the abs indicator on dash is flashing back and forth left to right. Brakes seen to work great. The brake lines have been changed to stainless braided by my brother and fluid changed about 5 k ago. The abs system dash light  has been going off after a few minutes of running. As I said it just started this. Any ideas?

Can you tell us EXACTLY WHEN in the riding cycle that the lights start flashing (like at key-on, or after engine starting, or after ride-away, etc?) -- this can maybe help us pin it down.

 

What happens if after the lights start flashings you stop the motorcycle, turn the key to off, then restart the engine & ride off?   Do the flashing lights come back on or stay off?

Thank you for your help, it starts right away as soon as started. I have tried while riding to stop and start engine but this didn't help. I just went out and turned key on and immediately it started flashing. Starting engine doesn't matter. Tried a restart and applied both brakes and just held them for awhile. That also didn't help.

I hope weather clears up tomorrow and I get to move it. I will say it looks like front reservoir is below middle marker. Can that be a problem? I see no signs of leakage. Thanks for everything and I'll surely be able to tell you more tomorrow.

No, the reservoir level being a little low should have no effect on the warning lights.

My ABS light was on also, as it turned out, the motor inside the ABS was the issue.  The contact brushes were FUBAR, and had to be cleaned and/or replaced. Unfortunately this is a completely sealed unit and BMW will not fit the ABS, you have to buy new. I found someone that would take the unit apart and repair/replace the brushes. Check out this youtube as this was exactly was....... https://www.youtube.com/watch?v=6m2H-nC0CqE

Wow Kenny, did your abs dash lites alternate while flashing? You know left to right back and forth. You could definitely be onto the problem. Thanks so much..

It flashed on/off and then eventually went solid. The brakes still worked, no problem there, but the ABS was not functioning.

Hey I did see a video while watching yours that said when a battery is changed sometimes the ads needs to be reset. The video shows how to do this so hopefully I can try this tomorrow.

Just keep in mind that the video linked to is for the later I-ABS gen2 ABS system, that system is a completely different type of ABS than is on your 2000 K bike. Your braking system doesn't use the same type motor brush set-up.

Just throwing this out here as I’m not sure if the K bikes act the same way than R bikes, but... At least on my 99 R1100RT, the alternating ABS lights flashing meant that the battery charge is low.

Thank you for your suggestion. I did try that and have a new battery that has 12.5 volts at rest and charges at 13.7 volts running. I did find out that others have had this happen when changing out the battery which is exactly when my problems happened. I found out that there's a reset wire which is a devil to get to but will effectively reset the abs memory. I will try this soon and I'll take pics and be sure to post if it works. I'm going to change quick connects on fuel lines so I will have Tupperware off so hopefully will make it easier to get to the reset wire. Just as some FYI on my bike it's pin #20 on the abs connector and is for the sole purpose of resetting memory. Apparently BMW doesn't want us finding it.

That #20 wire runs to the # 2 pin in the diagnostic connecter so should be relatively easy to access. That is the Brown/Blue wire (pin#2) in the diagnostic connector.

Yes that's it !  If I ever find that sucker I'm going to extend it to a sensible area under the seat in case I ever need to access it again. On my particular model its way under the battery tray from what I've been told. Should have a blue cap on it but I've had no luck finding it so far.

Ok got her all apart, It needed new fuel tank seal. I'm changing seal, fuel filter , tank hoses and servicing air filter. I am going also to try the ABS reset and will let everyone know how it goes. Also installed Stainless Steel quick Connects.IMG_20200321_104448785.thumb.jpg.a46f56e5cd4f0d3693f8bc6d3b2a2f39.jpg1526392993_IMG_20200321_104515059(1).thumb.jpg.dc72770ac5905e6c69ca90d5f7bd1613.jpgIMG_20200321_104503394.thumb.jpg.2599a1519340b1ecf41eaa65a6aa865f.jpg
