Reading SES code

Actually not for me, korndogg's check engine light is on in his truck, hes not sure which ports to connect to use the paper clip method of reading the error codes. Which are they?

yea he was tryin to figure out how the paper clip thingy works..lol

The two terminals on the top row, farthest right (passenger side)

that should do it!

providing its not OBD2..lol

Just go to autozone to get a FREE code key for GM cars.. just ask them and they have them behind the counter and yes , top right last 2 slots

i thought it was the top right, and bottom left. not sure though...

nope.. Top two farthest right

good deal...

Concerning this - son's car SEL light stays on and does not give trouble code - no code 12, just stays solid -- new pooter still same - any hints or tips?

is it OBD?

NO just the jumper to dump the codes.

what year is the car?? If its OBD1 then the jumper should work.. if its OBD2 than you need a OBD2 compliant scan tool or programmer

I believe they started using OBD2 in 1996.. I could be wrong

Also, you are not starting the car when you have the jumper wire in there are you? Just turn the ignition on, dont start it..

93 V6 - nope jsut sits there and looks real stupid. I've troubleshot sel's many times before - replaced chips and sensors never had the SEL not blink. 2 months ago ran well no light - started running crappy - local bidness put new plugs and wires on and ran good for a bit - now it stinks.
any tips or ideas appreciated
