Pulling Codes on 2004 Dodge Ram 1500

I'm not sure what else to tell you - this absolutely works. Starting in the OFF position, cycle the key to ON (where the instrument panel lights illuminate), then back one notch to OFF, back to ON, then to OFF, then finally to ON. Any stored codes will be displayed on the odometer.

Much to my dismay, I couldn't get this to work on the wife's Liberty either when the Check Engine light came on. I thought Jeep would work like a Dodge, but I finally decided that I was wrong and took it to the dealership and let them figure it out.

Ended up being a bad EGR.

Understood. I've done this probably hundreds of times in the past. I tried 3 times just to OFF, 3 times to ACC, 3 times to Key removal position and nothing seems to work. It's been a while since I've done this but my recollection is that if no codes are actually stored then it give a Pdone or something along those lines to at least let you know a test was run and nothing was stored.

That's interesting because my wife has a 2005 Jeep Grand Cherokee and this code pulling procedure works fine on that.

In response to Craig C. 's post. I thought everyone should know:

it does not work on the Liberty CRD with the VM-Motori engine. its not a Diamler crystler ECM. (from what a service manager friend of mine has told me)

In response to tcconrad 's post. I thought everyone should know:

switch all the way to the run position then back to off. do not hit the start position though. should work fine.

No luck.

Ah. Makes sense.

In response to Wing Nut 's post. I thought everyone should know:

How about this,

Stop pulling your codes! (at least in a public forum!)
