stlnet Posted May 1, 2009 Share Posted May 1, 2009 The story. After trying and failing with 4 different OBD2 readers, I finally managed to retrieve the error code stored in the memory. The solution was using the self-diagnostic connectors on my car, which is a 99 Subaru Legacy, B4. Beneath the dashboard, on the right side under the stearing wheel, there are two pairs of connectors. Two black and two green connectors. http://subarudrivers.net/media/obd2_a.jpg http://subarudrivers.net/media/obd2_b.jpg http://subarudrivers.net/media/obd2_c.jpg Connect the two black cables. http://subarudrivers.net/media/obd2_d.jpg And turn the ignition to ON (without starting the engine). This will set the car into test modus (historic codes is displayed) in the dashboard. Just watch the blinking CEL (check engine lamp). http://subarudrivers.net/media/obd2_1_2_sek.gif Every flash is +10 in value (light last 1.2 second). Three flashes, is the value 30. Seperated with 3 seconds delay, before it shift over to the singular system (+1 value). http://subarudrivers.net/media/obd2_0_2_sek.gif Every flash is +1 in value (light last 0.2 second). Three flashes, is the value 3. Together the value in this example is 33. I assume that connecting both pairs of connectors, will erase the memory, after you have started the engine. It worked perfectly on my 99 Legacy.

c_W_j Posted June 3, 2010 Share Posted June 3, 2010 a year old thread you say? I scoff at your primitive concept "time". anyway... the only connectors I found on mine that weren't together are the green pair. any wire colors I should look for coming from them?
