I've got a 2000 Excursion 6.8L 4x4 and I recently found the user code for the door keypad along with the main code. I tried to program a new code and the procedure does not work. I am 100% positive I am doing it correctly as I have practiced on my 2003 F150...and the procedure works.

The user code I found no longer works as trying to input a new one overwrites the old BUT the new one will not take. Can this be caused by a bad ECU?

I have other gremlins I am trying to sort out and I was wondering if the inability to create a user code would indicate the ecu?

Thanks...

 

No. The PCM has nothing to do with the entry system.

 

Ok...I didn't think so but figured I'd ask. Now I need to figure out if they are in the same location...maybe the PO cut a wire somewhere he shouldn't have. The truck used to have a remote start system and I have found cut wires under the dash behind the cubby hole but I could not find what they were for...

 

Maybe only some of the buttons work on it? If the code works with some buttons and you are trying to change to a different button that doesnt work it would not take. I am assuming that both codes you have do work.

 

As far as I can tell all the buttons work. in fact I wonder if the issue is that the last number in the main code is 1 which is the number you push right after the main code to input a new user code. When discovering the door codes, I found the user code first and then the main code. when I tried to set a new user code the one storred ceased to work which is what is supposed to happen but the new code I am trying to input never takes. hmmm, I will go outside and try a combo that uses just the numbers I know work.

 

Sure may be the problem, bad key, common problem especially when wet

 

I was just outside and all numbers seem to have a response (ie turns on interior light) so I assume they are working. I tried to make a new code using different sets of known good numbers but still nothing...

Is my procedure right??

1 - Enter main code
2 - press 1
3 - enter new code
--at this point the door locks should cycle but they don't.

By following the above procedure, it wipes whatever code was stored in memory, I think - that's why the old user code no longer works...

I'm at a loss here too...this whole truck has me about wore out.

 

Programming your own personal entry code
To program your own code:
1. Enter factory set code (keypad will illuminate when pressed).
2. Press 1/2 control within five
seconds of step 1.
3. Enter your personal 5 digit code.
Enter each digit within five seconds
of previous one.
Do not set a code that includes five
of the same number or presents
them in sequential order. Thieves
can easily figure out these types of codes.
Your personal code does not replace the permanent code that the
dealership gave you. You can use either code to unlock your vehicle. If a
second personal code is entered, the module will erase it in favor of the
new code.
If you wish to erase your personal code, use the following instructions:
1. Enter factory set code.
2. Press 1/2 control within five
seconds of step 1 and release.
3. Within five seconds of step 2,
press and hold the 1/2 control for
two seconds.
The system will now only respond
to the factory set code.

 

Also just because it lights up when you push the buttons doesnt mean they work correctly. The only way to know for sure is PID monitoring with a Ford scan tool. It could be for example showing a 1 with both of the first two buttons. Both work but one is obviously malfunctioning.

 

Do you have idea if auto enginuity would read that? I think I'm going to have to break down and purchase one...

 

No, I dont but most of those things are Ford scanner specific as far as I know, but then since I work for Ford I have had no reason to investigate.

One thing more to try, you know that if you push the last two buttons together that will lock the doors. So if it locks the doors you know those two work. So you could try a personal code with just those two keys to see if that works. If not likely a module failure, if it does work, likely a keypad

 

Thanks... I suppose it's the control module as I tried the combo of 7 and 9 already. I will go start reading up about replacing one of those.

 

Unfortunately that is a function of the GEM module on that model.

Generic Electronic Module (GEM)—Generic Electronic/Central Timer (GEM/CTM)
Removal

NOTE: The GEM must be reconfigured upon replacement. Refer to the scan tool help screen on the Ford Service Function (FSF) card to program tire size and axle ratio.

CAUTION: Electronic modules are sensitive to electrical charges. If exposed to these charges, damage may result.

Disconnect the battery ground cable. For additional information, refer to Section 414-01.
CAUTION: Use care when removing the instrument panel steering column cover (044F08) or damage to the cover locating tab may occur.

Remove the instrument panel steering column cover.
Unlock the retainers.
Remove the instrument panel steering column cover.

Disconnect the bulkhead connectors from the instrument panel fuse junction panel.
Loosen the bolts.
Disconnect the bulkhead connectors.

Position the instrument panel fuse junction panel aside.
Remove the nuts.
Remove the bolts.

Remove the generic electronic module/central timer module (GEM/CTM).
Disconnect the electrical connectors.
Remove the screws.
Remove the GEM/CTM.

To install, reverse the removal procedure.

 

Thanks again Sir!
