I jumpered A&B on the data link connector to get the "service engine soon" (MIL) light to try to blink out the diagnostic trouble codes. (The thing lights after driving for 10 minutes and then usually turns off after 20 more minutes. I suspect an EGR issue.)
Anyway, with A&B jumpered, the "ABS Antilock" indicator does the blinking of code 12 ("system working") over and over again, nothing more. The service manual says the "service engine soon" bulb is supposed to be doing the blinking. What gives?
