FAST CODES
At start of KOEO SELF-TEST and after Wide Open Throttle (WOT) request in KOER SELF-TEST, ECA outputs short bursts of information, known as FAST CODES, which were used by manufacturer during assembly. With most equipment, these code bursts are not visible; an entire code sequence lasts less than 1/2 second. If this fluctuation is visible on test equipment, ignore it.
