Well, I was trying to stay off the site for a week, so I could think about other things... Three days was more than enough of that crap!


OK, so here's the deal. I have tried and tried to search this, because I KNOW the answer has probably been posted any number of times, on several forums. But here's the thing...

NONE of the posts seem to have the exact same problem I do.


Here's where I'm at:

81c3 pulled codes for me a couple weeks ago. None to speak of.

PKE fuse appears to be in working order. I pulled it to "reset" the system, if that actually works...

Key in ignition and turned on.... PKE light on DIC panel illuminates for two seconds and turns off, as it is supposed to.

PKE fob is at the opposite end of the house, and my cell phone is there too. Because I did not want the unit too close, and I hear cell phones can cause problems.


I attempt to program the PKE using the owner's manual. Key on, engine off, push TRIP ODO button twice, then within five seconds, press FUEL INFO button. I hold that sucker in for twenty seconds, to no avail. The PKE light never comes on, to signal program mode.

I've tried this about ten times today, and no luck.


I did, however, replace my headliner today, and took several pix. I will do a write-up soon. The FSM was of no help on this project.




So, can anyone offer suggestions on what I might be doing wrong? Hopefully if I ever get this damn thing working, I like it enough to keep it turned on. I still don't know if the fob is any good. But I have no way of knowing that at this point.


I see one thing missing from your programming procedure that is mentioned in my instructions, that is the reminder to have the radio off. Likely you simply forgot to list that step but thought I would a least toss it out there.
The trouble shooting procedure for failure to enter programming mode in my 93 book is short but not easy to perform with common tools. If CCM codes 13 or 14 are NOT present it requires removal of the upper IP trim pad to access the PKE receiver and a digital storage oscilloscope to check the very brief 5 volt communication pulse between PKE and CCM over circuit 1455. If circuit 1455 integrity is verified replacement of PKE or CCM modules is indicated. Without a DSO about all you can do is check circuit 1455 (black with white tracer)for open or short to ground using a multimeter, if it checks good replacing the PKE receiver is likely the least expensive thing to try, good luck.
