The rear reservoir on your 02 has two chambers. The front one is for the rear brake and the rear one is for the front brakes. To bleed the wheel circuit you can get a long piece of tubing and run it from the front caliper back to the rear chamber on the reservor. Open the caliper bleed port and turn on the key and apply the brakes. The fluid will circulate in the hose back to the reservoir and run that until all bubbles are gone. Just make sure the reservoir never drops below the bottom. Same for the rear brakes only the tube goes to the front half of the rear reservoir.
The control circuits are done with the key off. Rear control is fed from the front half of the rear reservoir and you draw off the fluid on the long bleed nipple (inboard) on the ABS unit. manually pump the pedal and draw from the tall bleeder, keep the reservoir full. The front is fed from the handle bar reservoir and drawn from the tall bleed port on the ABS unit (outboard).
