Clearing Codes/Errors?

Hey guys,
Just a quick question for ya: How do you clear a code (such as if an indicator light that has come on that you wish to get rid of)? I know every vehicle is a little different, and I've never done it on a Jeep before.

Thanks!

Unhook the negative battery terminal and unhook the ECM. Wait 15 seconds and then plug in the ECM and then the battery terminal.

And welcome to the forum!

I will have to give this as a different option. In the FSM it states to disconnect the positive terminal and hold it on the ground for 15 seconds. This drains any possibility of anything holding a charge and is how I cleared a multiple misfire detection code after I forgot how to start jeeps.

Thanks guys for the replies. I was almost expecting to have to do some goofy routine like my Honda (press on the pedal, turn the key to accessories, press the Trip button, say Honda three times and pray...the usual)

Again, thanks!

So after you disconnect the positive cable from the battery you should physically touch the positive cable on the negative terminal of the battery for 15 seconds to clear the code? Scooby

Touching the positive cable to the negative battery post simply discharges the capacitors in the PCM that can store values you're trying to clear. That's just a bit faster method than disco'ing the negative lead from the battery for 1-2 minutes that will also clear any stored codes.
