Question about Yamaha FJ 1100 Motorcycles
Most of the time ABS problems are with sensers but which one? The master cylinder has a fluid level that sticks low evewn if theres enought fluid so makw sure it flates up in the fluild if the light stays on them check the wires and the plugs that plug in the wheel speed sensers as the sensers seldom fail but the wires abd plugs get into troble. Follow the wires from the sensers to the ABS controller and reconnect them and inspect all the covering and wires for troble. Most two wire sensers will have some continuity with an OHM meter but it will be high. If you meter has wave form then put in on one wire to ground with everything connected and turn the wheel and you should see pulse and its a yes or no answer. If the wires and the sensers check out and the levels senser can be proven to work you best let someone with access to the Yamaha dianostic equipment to look at it. Rember that an open brake line or an unbleed brake line will also make the light come on.. Unplug the ABS controller only with the key off and the battery unhooked as these parts are easlily damaged by spickes in power or a low or bad battery. Once all inspections are made and the battery connections cleaned and reconnecdted try again as you may have cleaned something up and it's making now and the system may work just fine
