ABS lights flashing on my 1100

[Sgt Bilco]

After months of careful preparation of my old 1100, all is in order apart from the ABS lights are flashing.

They are flashing alternantly and all the book says is there is an ABS fault!

Is this a simple fix?

check

that your battery is up to scratch. A low voltage will cause this there is also a simple reset that might be required. A quick search for 'ABS reset' on here will find it for you.

If they flash alternatively immediately when you turn on the ignition You have a stored ABS fault code! Do a reset and then try again!

If they flash alternately ONLY after you have pressed the starter button you have a low voltage sensitivity fault

If you need MOre info P.M. me

Mine does that, I think it needs a good battery charge, I can cure it by riding for ten minutes then doing a rolling bump start in 4th gear after turning the engine off using the key, though I still then need to stop the bike and move off again to set the ABS up as normal, the ultimate cure is a new battery or a good charge.

If they are flashing alternately as you say then re-set it by earthing the centre terminal in the abs diagnostic plug under the seat - it may have a blue protective cover.

Run a wire from the centre plug to the battery earth (the better the earth, the easier the reset), turn on the ignition, hold down the abs button on your dash for approx 20 seconds, keep the button held down while you turn off the ignition - that should clear it

Part of the ABS self check is the battery voltage. If you turn on the ignition and hit the starter as it is checking, it will read a very low voltage at the battery (due to the draw from the starter) and it will turn itself off as a safety precaution, due to lack of volts.
If you turn the ignition on, wait a few seconds till the ABS has self checked, then hit the starter, all should be well .
Also turn off the lights, heated grips and other assorted electrics.

Thank Steptoe for both of the replies
