ABS on K11100LT


Bud

Recommended Posts

Went to town today for a couple of errands. Started and stopped the bike several times in a row. Then, when I tried to start again it acted like the battery was low.

 

Coasted down hill, popped the clutch and started.

 

Then... my ABS light started flashing and wouldn't go off. Hmmmmmm..

 

Found a blown 1/2A fuse (didn't know they came that small) in a yellow inline fuse holder a little to the right and above the fuse box.

 

Stores closed. Will have to get a new one tomorrow.

 

Any chance that was my ABS problem? Any guess as to why it blew?

 

Late night wonderings.

Bud,

That 1/2amp fuse has nothing to do with the ABS. I caused the same fault on my '93 K11LT back in early '93. Tried to 'bump start' it after draining the battery and the rear wheel slid just enough to cause a fault. It would not reset so I had the dealer do it. This was BEFORE we learned so much about the ABS-I bikes.

You can read out the fault code and reset it easily.

Thanks, tried that out. However, I cann't get the hall sensor code to clear in order for the ABS code to appear.

 

Any help you could give would be appreciated.

Bud, I don't think you have to read the code to clear your ABS. Did you try this:

 

Reset ABS Fault

Connect a wire from a good frame ground or battery - to pin #2 of the diagnostic connector.

Press and hold the ABS switch on the dash, turn the Ignition ON while holding the ABS switch depressed for 30 seconds. (Some folks report this works better if you turn on the Ignition and THEN press the ABS switch for 30 seconds. Both methods have worked for me). Release the ABS switch, turn the ignition OFF, remove the ground wire from pin #2. The ABS fault code 'should' now be erased. Go back to the fault

code display procedure to ensure there are no more faults stored. Only 1 fault can

be displayed at a given time.

 

Also, if the battery is low, that will fault your ABS.

Bud,

Go back and read it again......the Motronic fault readout and the ABS fault readout are totally separate functions on different pins of the diagnostic plug.

Mick,

 

All I can say is "Duhhhhhh" dopeslap.gifdopeslap.gif

 

Thanks for pointing that out to me. I will go back and do it right this time.

 

Thanks again,

I followed these instructions:

 

ABS-I Fault Codes:

Connect the test LED (+lead to Battery + and -lead to Pin#2) Didn't attach a light because the instructions said K bikes didn't need on as a light on the dash shows the code (and it did for pin one)

 

Ignition ON.

 

The LED will flash a number of times ONLY if there is a fault code stored. Count these short flashes to determine the ABS fault that is stored in the ABS Control Unit.

 

Code Fault

1 Front Pressure Modulator

2 Rear Pressure Modulator

3 Front Wheel Speed Sensor

4 Rear Wheel Speed Sensor

5 Low Battery Voltage

6 ABS Relay in Relay Box (Not the ABS warning relay)

7 ABS Control Unit Defective

8 Possible Wheel Speed Sensor Gap Fault

 

 

Guess what, no code!!!! confused.gifconfused.gif

 

However, when I start the bike up, the ABS light blinks. The triangle light is lit but not flashing. Then, when I apply the front and rear brakes, the triangle light flashes as well. It used to stay lit till both brakes had been applied. If I push the ABS switch they both turn to solid red (no flashing).

 

BTW My volt digital meter is showing 13.1 volts.

Seems like I am missing something here. Any suggestions?

Bud,

Spend the BIG BUCKS and build the LED test lamp. The TEMP indicator on the K1100 only pertains to Motronic faults. Motronic faults are totally unrelated to ABS faults. crazy.gif

 

As for your lamp sequence, it sounds normal to me......left ABS warning flashes, center warning(triangle for lamp test circuits) solid until both front and rear brakes are activated once. Then both lamps flash in sequence until you ride off.

Mick,

 

Thanks for your patience and help. I didn't understand that the LED was necessary for pin 2. I'll get on it soon and report back the results.

 

Thanks again for your help.

Just to clairify. The lamps continue to flash when I drive off. They do not go out as they used to do. frown.giffrown.gif

 

I did go to Radio Shack and spring for the 12V LED. Ouch, $1.37 with tax. grin.gifgrin.gif

 

Came home and hooked it up to pin 2 and ground. Flashed 5 times Low Battery Voltage?????

 

Have a new battery on the way. Will wait untill I install the new one and then see what happens.

Bud,

The Low Battery fault on ABS-I is 'persistant" so now you need to reset it. Ground diagnostic connector pin #2, turn on Ignition, watch the ABS lamps flash, press the ABS momentary switch for 30 seconds, release the switch and turn the Ignition Off. Remove the ground you had stuck in pin #2 and turn on the ignition and start the bike. When you ride about 6 feet, the lamps should go off.

There ya go Bud, if you had to "jump" start your bike the battery was low. ABS hates a low charge. You said that you had 13.1 volts, was that on the battery or from the alternator? Seems like it should be about 14 from the alternator. I think the new battery will solve your problem if it is getting a sufficient charge from the alt.

After thinking about it, 13.1 could not have come from the battery so check the spec on the alt. to make sure the new one doesn't go south on ya too. thumbsup.gif

Fault code said low voltage.

 

New battery today and guess what? I have ABS again!!!! clap.gifclap.gif

 

 

Thanks to all who offered info. thumbsup.gifthumbsup.gif
