ANYONE HAD A SIMALAR PROBLEM THAT THEY FOUND A SOLUTION FOR? SHOOT ME A EMAIL AT gmantlr@yahoo.com

 

Are you using an OBD1 scanner even though the plug looks like OBD2?

So I Should Be Able To Jump The G And 5 Terminal And Watch The Check Engine Light Flashes Like The Older Style Obd1

 

No, '93 was the last year for that.

 

So I Have A Obd1 Computer With A Obd2 Data Link Connector And I Cant Jump The G And 5 Terminal And Get The Check Engine Light To Flash Codes. I Have To Put Wire In The G And 5 Terminal And Then Connect The Wire To The Obd1 Scan Plug In Order To Read Codes Or Monitor Sensors. They Should Of Made It On Or The Other Obd1 Or Obd2 Not A Obd1 Pcm And A Obd2 Data Conector. I Wonder If I Will Be Able To Read Sensors With Only Connecting Two Wires Between The Obnd2 Data Plug And The Obd1 Cable?

 

No personal experience with it but the obdi tool should work. You can also buy an optional adapter that fits between the obdi tool and the obdii connector - essentially does the same thing as the shbox link.

 

gmantlr:

Please turn the "caps lock" off. When the site software sees all caps, it converts everything after the first letter of each word to lower case, and you end up with a screwy looking post that is hard to read. I think you escaped with all caps in the first post because you coded the "smiley" and your e-mail in lower case.

 

Just use an OBD-I scanner with the correct adapter cable. Scanner manufacturers have this cable available. It's nothing new.

 

Thanks guys i figured it out with your help sorry about the capitol letter deal.
