K1200LT ABS-II piston fault reset
I had grayc03 over today because he had an ABS fault. Wig Wag lights from power on and NO ABS function. K1200LT 2000 ABS-II
Since I have a GS911, and he lives less than 20 miles away, I asked him over so I could reset it. The current version of code on the GS911 WiFi does do the reset.
At first I was expecting to see a failed wheel sensor until I learned it was alternating from key on so I knew it was a different fault. Once I got it connected up, I saw it was a piston fault so my heart sank and I thought the ABS module was probably toast.
I thought about it for awhile and figured that these ABS units probably have not seen any action in years, maybe 10 or 15 years as we don't go around trying to lock up our tires so the ABS system gets no exercise.
I went ahead and reset the fault and proceeded to see if the ABS system was working on a test ride. The ABS kicked in and immediately I got the wig wag lights again.
Not loosing hope for simple results of atrophy, I proceeded to reset it again and then to go out and exercise the ABS system. This time, the ABS system performed properly. gave no fault indication and I tested it again and again.
Here is a question to the gurus on the forum. Is it possible that some of these faults are simply caused by lack of use? Most drive not intending to lock up their brakes so the ABS simply sits and atrophys.
Time will tell if greyc03's issue comes back but I am going to ask, should we be intentionally exercising our ABS systems so they do not get sticky and cause faults from non use?
I regularly do both front and rear exercises both locking up the rear and forcing the ABS to work and also the front much more carefully usually on a wet road where I can apply the front brakes in short bursts to force activation without causing me to dump the bike.
Do any of you think there is any merit in a regular exercise of the ABS system to keep things free and properly lubricated inside?
Just wondering what other people think.
