abs light after service

hi was out for the first ride of the year.all my service is complete now

when i got to about 30mph i got alternating lights flashing abs failure & hazerd on the dash
everything feels fine. i did not have the brake system apart except for the front brake cylender was removed from the bars but not opened hydrolicly to change throttle cables. i did have the bike running in gear on the hoist to warn final drive & tranny fluids before draining. i did have the battrey unhooked at some point.
any suggestions i find this forum better than the dealer or manual

for such info

hi - don't know what year your LT is, butt I've heard that if you run the bike in gear, with the rear wheel off the ground, there will be an ABS fault thrown because the unit sees two different speeds in the wheel sensors and thinks there is a problem in traction. Don't know if that is your cause, and I'm not sure how to clear the fault, other than borrow a GS-911 from someone, or let the dealer clear the fault. Hopefully, an ABS guru will chime in here shortly.

Yes running through the gears while on a hoist caused the abs lights. I also learned this the hard way. ABS will have to be cleared with gs-911 or dealer.

Re: abs light after service

Try unhooking the battery and touching the positive and negative cables together. This should clear the capacitor memory in the computer. It will also clear all the radio presets. Be sure to do the throttle reset after reconnection.

  • Turn key on but don't start bike.
  • Twist throttle fully open and closed twice.
  • Turn key off.

Re: abs light after service

OK this is a 2002 bike and the faults will self clear once the cause is fixed. No need to undo the battery. You have the classic "wig-wag" lights which is normally caused by low fluid in one or both of the rear reservoir chambers. Add some fluid and all will be well again.
