trouble retrieving codes - 8/19/2008 3:36:06 PM    Erinsaccord   Posts: 25 Joined: 7/5/2007 Status: offline 95 Accord, 4 cylinder auto (non-vtec).  This has happened three times, and I hope that someone can help me.  The CEL comes on, I use a paper clip to create a connection between the two terminals on the service connector, and the CEL immediately goes off.  It stays off for several weeks (maybe 25 or so cranks?) and then pops back on.  What''s up? Thanks, Dave Post #: 1

RE: trouble retrieving codes - 8/20/2008 5:31:58 AM    Erinsaccord   Posts: 25 Joined: 7/5/2007 Status: offline Jim, How would I determine if it''s a bad ECU?  Would it be worth grabbing one from a junk yard to switch out? (in reply to JimBlake) Post #: 6

The Helm book says to try a new ECU, but thats easy for them to say - they dont have to pay for it... _____________________________ '03 Accord & '07 Civic '01 Saab 9³ & '05 9²x (in reply to Erinsaccord) Post #: 7

RE: trouble retrieving codes - 8/20/2008 3:48:51 PM    Erinsaccord   Posts: 25 Joined: 7/5/2007 Status: offline Took a look at the ECU this afternoon.  There are two units there, one marked for the transmission, the other for the engine (?). I didn''t take them off the platform they are mounted on. What''s troubling me is that the two wires that you jump together according to the online protocol don''t go to the large ECU, they go to the unit marked for the transmission! The other connector''s three wires go to the larger unit, presumably the engine''s ECU. This leads me to think that I am not testing properly and that the sudden turn-off of the CEL is proper.  Could it be that I have an early OBD II car that can be scanned using the three-wire connector?  (in reply to JimBlake) Post #: 8

Also the under hood sticker should say if the car is OBD1 or OBD2 _____________________________ This post was made by a REAL Hondadude, not the wanna be Honda_Dude 85 Yota pickup 235k miles "never say die" 22r engine. 92 Acura Legend 70k miles.

RE: trouble retrieving codes - 8/20/2008 6:10:18 PM    Erinsaccord   Posts: 25 Joined: 7/5/2007 Status: offline Yeah, I checked under the hood and it is definitely OBD I.  Also, nothing available behind the ashtray.  BTW, what''s the other service (three wire) connector for? Perplexed. (in reply to hondadude) Post #: 10
