Honda Accord d4 light on

Locate the 2 pin diagnostic connector behind the glovebox door. (Not the 16 pin OBD connector which is on the driver side). Hook a jumper wire from one terminal to the other. Turn the ignition on, but do not start the engine. Count the number of flashes the D4 light makes, looking for both long and short flashes. Respond with the number, and I'll post the diagnosis. (there are more than 40 possible codes, too many to list here)
