Start up current vs ABS fault

[Steve Fox]

If I start my S with either the handgrip heaters on, or with the high beams switched on, guaranteed I will ride off with an ABS fault. Too much current draw making the ABS software unhappy?

Yes Syeve, The BS system need full voltage in order to activate. Often when my bike sat for any length of time, (before Battery- Tender) I would start, ride to corner, stop & restart to activate ABS.

I fully agree,

I used to have the same thing with my R1100RT
I had to change my battery once because of it
They are used for policework overhere in holland and the police uses a stronger battery because they also have to cope with onboard utilities like a radio and extra lights. Soits a known problem with a weak battery

Common practice is to turn off all electrical devices you can, turn on ignition and let ABS lights flash together for twice and start. If it starts alternating flashes, then just ride off for awhile....you rode for years without ABS, so rding for a bit now, won't hurt as the brakes work fine without ABS. Stop in 10 miles or so and restart...should work fine.

I used to occasionally get ABS faults until I got out of the habit of flipping the ignition switch and then immediately hitting the start button. Now I wait a few seconds between and have had zero ABS faults since.

This may not be the only cause of ABS faults, but it has cured my problems.

Mark,

This is the only way to bypass the abs intentionally, and it works every time.

If you like off roading on your GS.....
