Thanks, Underscore. I'll add it to The Card Catalog.
A few notes on reading error codes:
ABS codes are read from the bike's diagnostic plug. It is under the seat and usually covered by a blue cap. (see attached pic) You need to remove this cap to access the diagnostic connector.
In case yours doesn't have the cap it should be the only disconnected wiring harness connector under the seat. You can further verify that you have the correct connector by verifying the wiring colors to it:
Pin 1: Brown/Black
Pin 2: Brown/Blue (ABS)
Pin 3: Brown/Green
Two ways to read the error code:
LED: It's recommended that you use a 12V LED so you don't have to mess with resistors. Ground the negative lead for the LED and stick a wire from the positive lead of the LED into the center hole of the diagnostic plug. Turn the bike on. If there are no ABS error codes stored then the LED should remain solidly lit. If there is an error code then the error code is determined by counting the number of times that the LED flashes off. If you don't get it the first time then don't worry. The LED will go solid for a little while and then repeat the error code and keep cycling.
Voltmeter: Connect the voltmeter ground to a ground on the bike. Insert the positive probe into the center hole of the diagnostic plug. Turn the bike on and count the number of times the voltage drops. (Note that this is best done with an analog voltmeter as most digital voltmeters don't react fast enough to let you count the number of voltage drops.)
RESETTING THE ABS CONTROL UNIT:
Before attempting to reset the control unit it's important to make sure that your ABS switch is working. This is easy to do. Turn the bike on and notice that the ABS lights are flashing. When you press the ABS switch the ABS lights should stop flashing and then remain solid if your ABS switch is working.
As noted in that document, run a wire from ground to the center hole of the diagnostic plug, turn the bike on and keep the ABS switch depressed for a while. (I usually count to 30.)
