 Posted: Sat May 22, 2010 2:37 pm Post subject: Question about low battery ABS faults |
 |
|
Any of you who have had low battery-related ABS II faults: Did you need to reset your ABS or did it come back to life without intervention when you replaced the battery?
The reason I ask is that I'm going to experiment with intentionally turning off the ABS on my RS with a switch that kills the power to the ABS.

On mine, the symptom being alternating ABS lights staying on, it fixes itself.

I have been un-able to get mine to reset. I am going to take it to the dealership at some point. They do turn off, if I power up while rolling...

Mine resets itself once the battery has gained some charge. I do need to switch off the ignition and restart the bike of course.

Thanks.
My is to put a switch on the ABS main power to disable. When I want to get it back, I'll return power to the ABS and restart. Good to know a reset apparently won't be required.

I would'nt count on it Drake, the ABS modulator is very sensitive to voltage fluxuations and spikes. It will probably need reset occasionally, and could become unresettable if spiked too often.
You can add a reset circuit for when you power it up and it does not auto reset.
Just my $.02

I don't plan to turn it into a GS. Probably wouldn't do it that often. I'd just like the option on rare occasions, like last year when I took an exploratory sidetrack in The Sierras and wound up on a silty dirt road which left me with essentially NO brakes due to the ABS. There was one hill I backed down and even going backwards the ABS left me hosed. I had to turn the bike off to back it down the hill without dumping it. It was a freaky experience.

Mine always recovers from low volts. IMHO switching it off should not cause any faults, if it aint on it cant do any tests, ergo none will fail.

Got the control-power hack from the IBMWR site on mine - as listed for the R1100, but simplified so that the control +12v to the ABS-II brain comes from the load-shedding relay; it's not doing too much with the headlight relays anyway. No probs with low batt anymore, ABS only initialises AFTER the starter finishes (and you can reset it while moving by pulling the clutch and restarting the engine again).
Disabling - I thought that's what the ABS switch was for - hold while turning ign on, flashes light then settles on single one under speedo to remind you it's off?? Might be wrong, been a long time since played with that...! |

My take on this is that the ABS still isn't getting full voltage even with a new battery, escept when the alternator is pumping, so maybe a bad connection some where still.
Can't be more specific until I've had to fix a similar pproblem.....

The switch doesn't disable the ABS, If the lights flash, ABS is already disabled, caused by a fault. The switch use is two fold :-
1) Stops the annoying & distracting flash particularly at night, but only for 5 mins.
2) IS used in conjunction with the 12" bit of wire to reset ABS fault codes.
