SES light reset procedure?

I know it's been posted before, but I can't find it...

Can someone quickly run through the procedure to turn off the SES light? I ran the code at Autozone so I know what the problem is (I've already changed the plug that was giving me a misfire), but the light is still on --> I have seen a procedure that involved the key in the acc position for x number of seconds, wait, crank, or something... but I can't remember the exact procedure...

little help? thanks!

I think the procedure you are referring to is for resetting the change oil soon light. ONly way I know to reset the codes is to clear them with a scanner. Could be that it will reset itself after a set number of cranking cycles after the trbl is cleared.

i thought you could clear codes by disconnecting the battery for like 10 minutes or something...

I have scanning software for my laptop so that is easier for me. One of my former co-workers used to disconnect his battery when he was trading cars to clear the codes, so I guess that is another option.

yeah i have herd that disconnecting the battery for like 15 min. will reset it. but if theres still something wrong then it will come back on again of course after a while.

also would anyone happen to know if theres any type of adaptor or something that exsists where you could plug your home computer in the car computer plug? may sound like a dumb question...

The software is free. The cable is what costs you. I've forgotten what exactly I paid for mine but it will do GM and Ford. I think it was around 135-140. It is the Alex Peper OBDII. May not be the best but it serves my purpose. I also bought a 50 ft. extension cable off the internet for about $15.

OBDII vehicles require a scan tool to reset the light. It will go off by itself once the problem is fixed after a set number of drive cycles.

This works on most '97 and up GM "F" and "W" body cars:

Remove battery POSITIVE cable.

Take ignition to full on/start position and hold for minimum of 1 minute.

Take ignition back to off. However, key will not return to off and will be stuck due to lack of battery power.

Reconnect battery positive. Various relays will chatter.

Now take key forward then back to off. It should now remove.

Re-insert key and start engine. SES should be off unless a Class "A" DTC error code immediately triggers it.

This resets any and and all DTC error codes stored and WILL clear a SES light. If it doesn't work then you will need a odb-ii scanner with reset.

BTW - If it works don't ask me how or why it does.

Good luck!

I've been looking at the AutoTap OBDII software and cable for PC's. Anyone have any experience with this product? The link to their web site is

Yes. I've had AT for two years. I run it on a Dell Laptop. I checked my knock retard that way before getting a special autoscanner meter.

You can monitor key activity like 02 sensor activity, etc. on a virtual gauge display. You can put up several virtual gauges. Plus it will read odb-ii error codes and reset the SES light. Makes you look hi-tech.
