How do you manually get ABS Flash Codes?

Got a hunch you figured this out by now but, I'm pretty sure it takes a dedicated ABS scanner. If you know otherwise please let us know.

Connect jumper wire between DLC terminals Tc and E1. If a code is stored, 4 seconds will elapse and ABS light will begin to flash a 2-digit code.
First number of blinks will equal first digit in code. After a 1.5-second pause, second number of blinks will equal second digit in a code. If 2 or more codes are stored, a 2.5-second pause will separate codes. After a 4-second pause, all codes will be repeated .
