got an alarm "predator 4001" i installed it and it does open/close doors and trunk and starts the car but turns it off 5-10seconds later

manual says:

After remote starting your engine, the Predator system will shut off the engine immediatly if the ignition is OFF and any of the following occurs:
1. hood is opened (controled by a switch this is NOT the problem)
2. the brake pedal is pressed (didnt touch it I swear :P)
3. The Remote Control Button is pressed (not pressed guaranteed)
4. 20 or 30 minute programmable run time is expiered

factory setting by default for car to run is 20min....

it also says car wont even turn on if hood is open or break is pressed
so that rules 2 of thouse out
i set car to 30min and same issue occurs

it cant be the remotes... does it with both... lol


does anybody know about ignition?
i got 2 wires
Ignition 1 RED / Light Green (+)
Ignition 2 BLACK/ Light Green (+)

BUT alarm only is asking for one. i got it connected to RED / light green

anybody know about the ignitions and which once are/arent requiered?
should i hook them both up in parallel? but i dont understand why i would need to cuz car starts already... uhhhhhhh

HELP!




also i got "remote start armed signal" canle disconnected and I dont know what to do with it.
it talks about running continues power while autostart is running.
could it be "Alarm Input Wire: BLACK/ LIGHT BLUE (+) IN # PIN GRAY CONN BEHIND PARK BRAKE" ?
any ideas guys?


btw i got 1997 Ford Thunderbird 4.6L V8


Thanks

I know im a noob but i did a search, google and here and everywhere./ dont know what to do from here :S

You probably do need to connect both ignition wires.

Also, have you learned the tach signal properly?

oh, and don't forget you need a PATS bypass module...

The second ignition line that behicle seems to only power the heater.

As far as the 'armed signal' wire you're talking about should be connected to a PATS immobilizer by-pass module like init mentioned. It's required since your vehicle as a factory installed immobilizer.
This most likely explains why the vehicle runs for a few seconds and turn off.

PATS bypass module?
what does it stand for? does my car have it?
ill need to search for that because i got no clue what that is :S

thx for help guys ill google PATS for now unless you can provide me some more info :D

Ooops!  I'm sorry, I looked up Ford Mustang!  No, I guess you don't need it, I don't see a reference to it in DEI's bypass application chart.

I'm sorry.  Although that still doesn't solve the problem totally...

If you're using voltage sense, make sure the system is programmed to do so.  If you're using TACH mode, then make sure you've learned the tach signal and that the tach wire is making a good connection.

As for that other ignition wire, the main reason why people install remote starters is to warm up the heater.  You'll probably want to connect that wire.  Don't just hook it into the other ignition wire.  I'll have to look at the install manual to see exactly what needs to be done.

Is there not a small light in the dash that flashes or lights up 'theft' or somethign to that effect??

Also does it over crank when it starts? If it doesn't then the tach is programmed successfuly... At least I think it may be the case.

nothing about theft
car fully starts and runs for like 5-10seconds
techtometer is connected propertly as that is when my alarm was allowing me to program it. it was starting same way when tachtometer was unplugged though

here is another thing
when i take my car off alarm it wotn start right away... i need to press a few buttons on a remote and then it allows me to start it (with the key ofcourse)

do you think i can just unplug thatbig harness with alarm wires and try using just the starter? (there are 2 mandatory wires brake light and hood switch i might need though)




Posted By: init
Date Posted: September 10, 2007 at 10:29 AM

No, you can't do that because then the system won't have power.   As far as needing to press buttons, the system itself probably has a type of immobilizer feature where it prevents someone from starting the car while it is armed, but usually that's deactivated when you disarm.   What buttons do you need to push to get it to work?

I looked up a wiring chart on this vehicle but I think mine might have an error.  It lists both "Ignition 2" and "Accessory" as GRAY / YELLOW and it doesn't mention a BLACK/ Light Green wire.  Also, it says that this car does have PATS.   (I made sure I was looking up the T-Bird this time, too.) That isn't consistent with other information I've found or your findings.

Next time you try to remote start the car, try this:  put the key in the ignition, but don't turn it, then activate the remote start.  If it works with the key in, then you must have PATS.  If not, then that isn't your problem.

thanks init I will give it a shot
however alarm manual says that if key is in ignition it will not start. so this can go 3 ways
1. car wont start
2. car will start but will turn off shortly
3. car will start and wont turn off

car appears to let me start it after i lock and unlock it once again

I found different wiring digrams but currently (commando security i found ) digrahm says:
ignition RED / Light green
2nd Ignition Gray / YELLOW

right now i got it connected through RED / Light green
would it matter if I use other one you think?

hey question to you
if i leave the key in the ignition with an open door it makes beeping sound to let me know key is in the ignition. would that anyway confirm my car having PATS?




Posted By: catalin capota
Date Posted: September 10, 2007 at 3:33 PM
You should definately have a factory installed immobilizer. Vehicle computer sees an attempted theft and will not let you start the vehicle with the key after a little while.
Install the PATS system and you're done.

I don't see how the alarm would know if the key is in the ignition as long as it is in the OFF position, in other words, leave it in the position where you can take it in and out.  Then try remote start.  If it starts OK, then it's PATS.

It would seem to me that, if Ford was using PATS in other vehicles at this time, I don't see why they wouldn't have it in this one.  But, best to check to be sure as you don't want to buy parts you don't need.

i tried with key in different positions and same issue is occuring. if i put key to position right before last one car wont even attempt to start.


a guy from my thunderbird forum said i dont have PATS

however i found DEI 555L GM PASSLOCK II BYPASS MODULE 4 REMOTE START!
that does list my car... UHHHH


i dont mind buying that part even if it dont work but i dont even know how I would hook it up or to what I would hook it up.


you guys want me to buy it and try it?

If you tried starting it with the key left in the ignition, and that didn't work, then PATS isn't your problem here.

As far as that other site goes, I'm going to say that it's wrong, someone else can correct me if I am, but to my knowledge Passlock isn't used in Ford vehicles.  From what I can see DEI's reference chart doesn't refer to the 555L for any Ford vehicle.  You don't need it if the car isn't starting with the key in the ignition.

Perhaps, it's possible that that second wire is controlling more than the heat?  You might want to try connecting that now and see what the outcome is since you'll need to do it anyway.  Remember not to just connect the 2 wires together but you'll need to use a relay.

This document: https://www.designtech-intl.com/pdf/notes/note234.pdf

has a good diagram for how to wire 2 ignition wires from just one output.  Don't pay attention to anything except the first diagram on the page, as the rest of it is irrelevant to your particular system.  The diagram you're looking at has the one wire coming out of the box that says "DesignTech" and going to two relays.  In the box that says "DesignTech," just imagine that's your Commando remote starter system and where is says "Green Ignition 2" that's your PINK ignition wire from the Commando.

Apart from that, all I can say is have you checked the tach wire lately?  Are you sure it's making a good connection?  Make sure you aren't using TTAPS.  Some people here swear by them but I haven't had much luck. 

Does the remote start system have any way of reporting what the failure was through the LED, flashing lights, chirps, maybe?  I know my DEI Viper system can flash the LED, but I have not been able to get a lot of information on the Commando system.  If you know the manufacturer's name, please post it and I'll try to get what I can on it.

My info show's 1 ignition (RED / green) and 3 accessories (two grey / YELLOW and 1 BLACK/ green).

make sure you hook up tach and then do MANDATORY tach programming.

Aha! That explains it then. The Code Alarm website says that one of the Gray / YELLOW wires is ignition and one is accessory, though. They fail to mention the BLACK/ Green wire but the OP does mention it.

I would strongly suggest testing each of these with a multimeter.

Accessory Wires have voltage when the key is in ACCESSORY or RUN positions.  The voltage usually drops or goes away completely when in the START position.

Ignition Wires have voltage when the key is in the RUN or START positions.  They don't lose voltage or power in START.

Starter Wires only have voltage when the key is in the START position.

All wires have no voltage when the key is in the OFF position. The ones that do have power at this time are your constant 12V sources.

Make a note of the wire's color and how it behaves during each key position. Now you'll know which ones need to be connected to what lead out of the remote starter. Reference the document above to see how to connect more than one wire to a single output using the relays.  You can get relays at auto parts stores.

init & extreme1

ill try connecting 2nd ignition wire instad of 1st one and see what happence. ill look into relay as well

tach wire is connected correctly. I know that because alarm wouldnt program untill I connected it. Also I did mandatory RPM programing and alarm gave me a confirmation as it said it would.
just to verify = tach -> techtometer right? I dont know what TTAPS is and i dont see it on my diagrahm. what does TTAPS stand for by the way?

Alarm doesnt report falier. BUT it does try 2 more times in the manual it says:

"If the engine does not remote start, the Predator system will attempt to start the engine two additional times."

so alarm does not think that car unsucessfuly started, right?

because if i press brake or press started again it wont try 2 more times. so that would mean car somehow doesnt know car is running...

im really starting to think about 2nd ignition or using both through relay as you are saying init... what you think?

i will get a voltmeter from my dad this weekend and test it out.

thanks alot for your help you the man :D:D:D

Use a digital multimeter.  It's safer on the car especially if you find that you need to test wires that are part of the car's sensitive electronics.

Yes, Tach=Tachometer.  When testing this wire you'll need to put the multimeter into AC voltage mode, and keep in mind that it should fluctuate when you rev the engine.

T-Taps (which I had written in all caps) are a type of connector that is sometimes used by installers in automobile wiring.  There's a whole 4-page thread that cropped up on here not long ago where people are debating wether they're any good or not.  Some people swear by them. Personally, I haven't found them to be that great.  Your mileage may vary.  I would suggest that if you used one of these, try using some other method of connection and see if that works out better for you.  A T-Tap is a plastic connector with a metal "fork" that you fold over the wire and snap down, then you crimp a connection on the other wire and "plug" it into the plastic peice.  Don't confuse it with Scotch-Locks; they're similar but not the same.  If you don't have a clue as to what I'm saying a quick Google search should find some pages with a pictures of these.

If the remote start system tries to start again than it knows that the engine has stopped (or it at least thinks that it is) and it shuts down and tries again. If you push the brake it stops trying again because the brake is a shutdown trigger.

On my Viper system, you can find out what made the system shut down last time.  You hold down the program button, turn the key on-off, then let go, and the LED will flash 'x' number of times.  The manual tells you what the flashed code means.  Obviously, this method wouldn't work with your system but there may be a way to find out if you look in your manual. You'd need to let the system run all 3 times without interrupting it to see what it says. You may also want to re-learn the tach signal just for good measure.

that makes ALOT of sence to me. i think that might be exactly what the problem is! im going to delay this untill weekend as I cant spend anytime on this during a week (gf bitches lol)

but will definatly check with voltmeter and possibly try changing them.

I will keep you posted over the weekend. ty :)

you know i actually right now for Ignition have it hooked up to RED / Light green
My Commando Vehicle Security website chart says:
Ignition RED / Light Green
2nd Ignition Gray / YELLOW

I had it connected to Gray / YELLOW before and it wouldnt work at all.
There are 2 gray / YELLOWs though
i think i might try hooking Ignition to 2nd Gray / YELLOW on a weekend

You need to power all 3 wires at once.  That's what the relays are for.




Posted By: eg0rka
Date Posted: September 11, 2007 at 12:31 PM
wouldn't i just need 2 ignition wires tought?
use voltmeter to figure out which are ignition wires as you describes before and use 2 relays for thouse?

by the way do you think I can pickup relays in any car audio shop? any special relays I should ask for?




Posted By: eg0rka
Date Posted: September 11, 2007 at 1:35 PM
"bangster" from TCCOA forum said he used both grey/orange wires for his autostart but he used one relay
it does seem that relay will be needed regardless. i will stop by a few places see if I can buy a couple.

any recommendations on which Relay to look for?




Posted By: catalin capota
Date Posted: September 11, 2007 at 7:09 PM
Why don't you do this.

With a couple of jumpers and the key IN the ignition in the OFF position;

- jumper from constant power to ignition 1
- jumper from constant power to ignition 2
- pulse constant power to starter wire till vehicle runs

Does it keep running now? If so then you need a immobilizer bypass.
If not then you don't have the right ignition wires connected.

Looking at the PDF file here

Just to Verify I connect 30 and 87A in parallel
and then we got 3 seperate cables ground, 12V and alarm input?

im not sure what that round thingie mean between 85 and 86




Posted By: init
Date Posted: September 11, 2007 at 8:35 PM

Don't worry about the curly line between 85 and 86.  That's just showing you that's the coil inside the relay.

85 is connected to the output of your alarm, 86 is connected to ground.

87 is connected to a fused constant 12V source.  Make sure if you're using this to power an ignition wire that the voltage on the constant 12V doesn't drop out when the vehicle is starting.

30 is connected to the ignition wire in the car.  Nothing is connected to 87a in this application.
