Hey folks,

Yesterday after a short ride my ABS and Brake lights began blinking simultaneously (fine when I stopped, began blinking after the bike sat for about an hour). Pressing the ABS switch has no effect. From info in the many threads on the subject I gather that battery level may be a likely culprit so will have a look there (PO indicated the batter is getting old). In the meantime I do have a couple questions to clarify some things.

Thanks in advance for any info!

Hi Lee,

I can't help you with the fault code bit, but I can tell you the switches are very easy to get out, and also very easy to take apart and clean. And yes, the contacts do get dirty. Sometimes just spraying something (WD-40 - which I would never use on a dirty switch) will bring the switch back to working condition.

Lee,

FD's post on the Tech Resource subforum is a good place to start.

Good luck.

John

Thanks John. Been through that and referenced it in my original post here Smile

Clarifying question is to information provided in that post.

Scott_Anderson · Posted: Mon May 09, 2011 10:15 pm Post subject:

Lee, you are having two issues here.

1st the temp light only reads the motronic faults(pin 1 of the diag connector)

2nd you will need a 12v LED to read the abs faults.
The + of the test LED goes to the battery + terminal.
The - of the test LED then connects to pin #2 of the diag connector to read the abs faults.

The rest of the instructions should be fairly simple after that.

OOPS!

REALLY tired tonight. Too many things going on and trying to get everything together before HM.

Have you searched thru IBMWR?

No worries John and yeah, I use IBMWR as a resource as well.

Thanks Scott for clarification on the temp light. Yes, the rest of the instructions are very clear and shouldn't be a problem. Use of the temp light for other diagnostics was the ambiguous bit. Will hit Radio Shack today for an LED. Had the battery on Tender Jr. since getting home from work yesterday so we'll see if that changes anything.

In the meantime I stand ready with electrical tape for the morning's commute.

Electrical tape has been my fall back temp. fix. Very Happy

One time I had tape in place over the abs light show- several days later I happened to look at the gauges at an odd angle and noticed that the system had reset itself! Go figure.

Spent some time last night disassembling, cleaning and rebuilding the ABS switch. It was definitely a mess. Works with a nice 'snick!' and now does what it's supposed to do. While inside the switch I noticed that everything is in place to accept a light under the ABS lens. Might try fiddling around a bit to see if a permanent ABS diagnostic light solution is possible/practical.

The not-so-permanent LED diagnostic light is currently offering an error code #7. Or is it #6? The Tech sticky indicates that the short flashes are counted so would the following sequence be code 6 or 7? "____" is the light steady on.

Ignition on: ____ 1 2 3 4 5 6 ____ 1 2 3 4 5 6 ____

When counting along with the flashes I want to include the final long light but am thinking that might not be right.

Question regarding ABS reset: are there any visual (some light does something), auditory (relay clicks) or other measurable event (stuff multi-meter in some connector and watch for something) which indicate that the reset has occurred?

Bump to the top to hopefully get some clarification on 2 things.

First is about reading the ABS code. Is the following sequence a 6 or a 7? "____" is the light steady on.

____ 1 2 3 4 5 6 ____ 1 2 3 4 5 6 ____

Second is regarding ABS reset. Are there any visual or audio clues that the reset happened?

Thanks much!

I would say that the flashing sequence you have there is 6. don't count the long only the short.

the only visual would be if you try and read the code after reset and there is nothing there. no audio.

Thanks Scott. Yet another reason to pull the gas tank adn crack open the relay box. Wink

Have there been any successes rehabilitating dodgy relays? I would presume that testing a relay is as simple as locating the correct pins and direct connecting to the battery with a fused jumper wire?

I haven't had any experience with the abs1 systems, if you are close to Drake I'd bet he could help you diagnose it further in his garage, and/or have some replacement parts for you as well.

To do a reset only requires 18" wire, A flash of 6 means ABS relay fault, not had that one myself.
Do Not leave the LED in circuit whilst doing a reset, causes confusion in the brain. Disconnect LED, Do a reset, ALL off, then re read pulses.
Does the reset switch make the flashing dash lamp stop for 5 minutes, if not the switch is still faulty & you will NEVER reset the ABS ?

Thanks Tim.

After rehabing the ABS switch it does stop the blinking for about 10 minutes (both lights on solid). Have been attempting the reset without the LED in circuit. Bare wire into the middle diag jack slot (#2), alligator clip to the ABS modulator mounting bolt (confirmed good ground with a continuity tester).

I'm guessing at this point that since I cannot get the thing to clear that the relay is toast and until it's changed out the fault code cannot be cleared.

Will be hooking up with Duck to diag a few things next month and this will be on the list.

I definitely appreciate that. Will update this thread after testing and, if necessary, replacing the relay.

Hi Lee

Did you get to the bottom of your ABS error code 6 ? Did a new relay cure the problem? and if so were there any test you were able to do before replacement that proved the point?

I ask, as I have a very similar situation with my '93 K1100RS too, and would appreciate any steer you could give...

Many Thanks
