CJK440 Posted March 3, 2004 Share Posted March 3, 2004 Any way to pull codes off my 96 Legacy without a scanner??? Like jumping some pins on the diagnostic connector and reading the Check engine light??? How about clearing codes??? Do I need a scanner to clear the codes???

99obw Posted March 4, 2004 Share Posted March 4, 2004 MY '96 vehicles use OBDII, so you will need an OBDII code reader to read and clear the codes. Quote Link to comment Share on other sites More sharing options...
ShawnW Posted March 4, 2004 Share Posted March 4, 2004 Autozone used to pull codes at no charge. Clear them by disconnecting the battery and letting it drain overnight. (not sure on actual length of time but overnight works). Quote Link to comment Share on other sites More sharing options...

I thought the basic codes could still be pulled,stupid lying article,oh well my bad. In regards to resetting the ECU,I have always disconnected the negative and just put my foot on the brake pedal for about a minute,seems to drain any power from hte system and has worked on all my cars,maybe the OBD II is different though? Still learning. Quote Link to comment Share on other sites More sharing options...
99obw Posted March 4, 2004 Share Posted March 4, 2004 From Subaru document: On Board Diagnostics-II (OBD II) Module 407 "DTC Memory Memory of a DTC (as it relates to illuminating the MIL) is maintained until 3 consecutive passing trips have been made. (The Enabling Criteria was reached 3 times in a row and the tests were performed with good results). The MIL will turn off at this point. The DTC will remain available for viewing with the select monitor and the freeze frame information associated with it for 40 warm up cycles. The exception to this rule is if the code is associated to misfire or fuel trim which will require 80 warm up cycles for full erasure."

99obw Posted March 4, 2004 Share Posted March 4, 2004 Maybe a little more info would help. DTC = diagnostic trouble code ( i.e. P0400, my favorite) MIL = malfunction indicator lamp (check engine light) "Before OBDII can begin to work the vehicle must meet the “Enabling Criteria”. This is the vehicle operating condition that must exist for the Engine Control Module (ECM) to begin diagnostics. “Enabling Criteria” will not be the same for all diagnostics. For example; the ECM checks an EGR solenoid as soon as the ignition is turned on." Quote Link to comment Share on other sites More sharing options...
