okay here is my issue, the pke stopped working and somehow is turned off. i tried the reprogram thing, nothing. tried the door button with keys out of ignition, nothing. keys in the ignition, nothing. the hatch button does not work either.
new battery, same thing, absolutely nothing. whats going on here? i checked all the fuses, and checked the receivers, all good. receivers are connected and wires are in good shape. what has happened here??

 

PKE? Write it out so we can help!

Thanks,Matt

 

passive keyless entry

 

This may be a dumb answer but try changing the battery in the FOB. They don't last that long

 

yea i put that in my original post. changed it a few hrs ago...nada. thanks tho, ive made dumb mistakes like that before!!

 

What fuses did you check, how did you check the reciever? That involves taking the dash cap off. Did you do that?

Here have a look at this thread, it may help.

Sorry to DP again but a simple search turns up so much information on these PKE issues it's hard to believe anyone who owns a C4 and visits these forums has one that doesn't work.

I don't know if this search result link will work or not but here it is...

And I'm not picking on you merlot566jka, I see it from a lot of even older members.

It's not that I don't like to help people, I try all the time but posting the same information over and over again gets old real fast.

I know I'll get bashed for this post but I'm starting to see why older members than me start threads about searching.

EDIT: just so you know I'm not just telling folks to "use the search" here's how many times I've talked about or tried to help with PKE issues...

The power door locks are wired through the PKE, do they work?

 

Does your "PKE light" on the DIP light for 2 seconds as you turn the ignition on?

Can you go into the program mode as indicated by the PKE lamp?

Does dionostic mode work?

Have you put the system into the non-passive mode by accident?

I have done extensive work on my own PKE system and ALLT4 has really layed out great info in his PKE post. I will not re-invent the wheel but just say the PKR receiver interfaces with a lot of other inputs and outputs from the car which will effect the operation of the receiver.

 

try this if the pke light does not come on when you start the car the system is turned off very easy to turn on, walk up to the car press and hold the door unlock botton untill the door locks cycle twice now just walk away you will be armed and ready to rock

 

thanks man, no offense taken. i tried to search for pke and got like 12 results. your results are helping tremendously! a few more hrs of diagnosing and ill be where i need to be. another thing has come up in the reading, the door chime...it doesn't work. i noticed it after reading these posts, and never really thought about it not working!! i guess I'm off to rip apart the dash and ignition lock!

 

Slow down, no need to take apart the ignition lock. That specific switch can be checked by one of the wires on a plug for the PKE receiver. You can just check the resistance by putting the key in and out and check for open and closed condition (no books here now).

Has the chimes been working with door or headlights? how about before PKE problem? Perhaps your chime box is bad also...or is it?

It would be a great help to have the GM red books (FM) for this kind of repair.

Really need to know if you have any activity on your PKE light on the dash (DIP, drivers information panel).

 

A4 on the PKE module plug will go from 12 volts to 0 when you stick the key in the ignition. LT GRN wire.

Not a resistance check, per say.

Unlikely, if he can't program it how will it re-activate the system?

 

kalister1, door locks work fine.

pcolt94, no the light does not come on when the car is started.
yes i can go into program mode.
diagnostic mode works, but the code never changes when the transmitter is brought within rage, code stays as 13. is it supposed to blink a set # of times before it changes code? it blinked 3 times and i brought the fob over...stayed as 13.
i may have turned it off, but the fob doesn't even work to open the locks or the hatch. no response out of the fob at all.
checked the voltage at the pke module. all is well. everything is getting the right amount when its supposed to(good write up on the diagnosis!! the dash wasn't fun to pull apart. but pull apart-test and reassemble took just under 2 hrs!!)
chime module is just retarded. i think i need to get a new one. all the wires checked out good there too, i think the module is just going bad. i got it working temporally till i can find the time and money to get another. i used electrical tape and paper towels to hold it in a position where it will work.
which book is it for this #1 or #2?
the diagnostic mode and the program mode work fine. the fob seems to be the culprit. but to drop 150(have to get from dealer don't have time to get one online(gf and i are going to go get Adam Boca's vette on the 24th and off to Oklahoma after that). express shipping from one of the ebay guys will cost the same as going to the dealer +/- $10) seems pointless if its not the problem.

ALLT4 doh!!

 

does anyone else think its the fob?

 

I'd say you ruled out every last possibility, I assumed erroneously you had two FOBs for some reason and neither would program, sorry. It'd be nice if you had another one to try before you bought a new one to confirm. Like that happens that often, get a new or used one and give it a try.

If you found any of my old posts on this issue I had almost the same trouble. After all my troubleshooting and repair, turns out the FOB was also dead. I managed to fix it by re-soldering every connection and feed through in the FOB. Especially the IC in the FOB, it had some "iffy" connections on it.

After I re-soldered everything it worked perfectly and still does to this day. You better be good with a soldering pencil if you want to re-solder it though.

Press on, when you get it working you'll have more knowledge and self reward no aftermarket system could bring. When the PKE system is working the way it's supposed to and you take the time to actually read your owners manual and understand how to use it's features, it's a great system.

 

Here's the flowchart from my 96, I believe the 94 uses the same PKE module so it should work. Just if you want to follow a specific procedure one last time.

 

following the flow chart you've posted I'm brought to where it says are antennas OK? check antennas.
any insight as to how i would check them other than verifying that they are there, not broken and wires all look in good shape? everything seems to be OK on them. the one in the drivers door was a little dirty, i wiped it off, other than that they both seemed fine.

i have been soldering since i was 14, i think ill give that a shot. plus I'm bored and tired of messing with this pke and it will give me a good change of pace to sit down in the ac and try to fix things.

allt4 you're saving me so much money, i don't have to buy a book, a pke module, or fob(yet). i think i owe you a beer or 12!!

 

This flow chart ASSUMES you have a good transmitter so keep that in mind. It's a chart for troubleshooting the PKE receiver, not the FOB. So naturally if the DTC doesn't change from 13 with an assumed good FOB in range, the flowchart leads you to the antennas.

Just make sure when the DTC is flashing 13 and you bring the FOB in range, move it around quite a bit, it could be asleep. Shake it like you mean it, the tilt ball could have some dirty contacts. If it's the sealed type though it's unlikely it's dirty.

 

IT WORKS IT WORKS IT WORKS!!!!
i re soldered all of the ics and resistors. and then from ur tip about shaken it like i had a pair got me thinking. i looked and it wasn't sealed ball type. i used some cleaner that i used on the maf. and bingo. works perfect!!! I'm so ecstatic!!
honestly if your going to be at carlisle (since ur in PA anyway) ill supply the beer for the weekend, or water if ur the non drinking type. i appreciate your help greatly!!
