Date Posted: March 12, 2008 at 2:44 PM
Im pretty sure I have all my connections made but when I try to use the trasmitter for the 5900 nothing happens, no arm/disarm or anything.....also I tryed to program my Xk531 following the directions but the led on the unit will not come on like said. Im really not sure what to do. Am I supposed to program every function on the transmitter or should it just work when everything is done? I really need this finished today so any help is appretiated. Thank you.

you cant program the Viper or the Bypass module?

Nothing seems to be working at all.....No leds or anything. The only wires I dont have hooked up are the nuetral safety, domelight supervsion and the panic wire on the xk531. I guess I have to get the xk531 programmed before the alarm itself will work. But the led on the xk531 isnt comming on when I follow their directions.

the neutral safety if on an auto, just ground that wire. The domelight isnt needed, but nice to have. do you have the ignition wire connected/ you need this to program.

Thanks for the info on the neutral safety. I have all the other wires hooked up except the ones mentioned (which should have no effect on the alarm turning on/off). The xk531 when programming the transponder has a list of things to do: one key in turn ON 5 seconds, off. then second key 10 sec. etc, etc. then it says the Led will come on but I get nothing....So I dunno.

No I didnt test :( I went by a diagram I printed out. I went out there minutes ago and tested my 12v constant wires, and ignition and they were o.k. also noticed my Check engine light and Brake light on the gauges were on.......o boy.

01 Grand Cherokee/ 4.0L I didnt think it was that serious, especially when the couple of wiring diagrams I printed said the same thing. But I guess it is, and I know that now. hmmm....I dunno what to do, maybe just start taking wires off.

but u neva know...a maniac could've put together the info those diagrams were based on....lol...thats why u wanna test all wires prior to connection... another thing is sometimes even the manufacturer will change some of the vehicles wiring.... there are always lil inconsistencies in anything mass produced...remember that!!!! ------------- there can be only one.......

K thanks. As i was looking at everything I noticed I possibly have something incorrect. My RED / WHITE 12V input from my relay satellite I have hooked up to the 12v constant power input of my 5900 primary harness as well as the 12v constant to the xk531. Then the other two RED wires 12v input for high current outputs are both on my 12v constant at the ignition switch. Sound right?
Posted By: skee-weezy
Date Posted: March 13, 2008 at 10:23 AM
sounds rite...but u should probably connect all of those directly to 12volts at the ignition individually.... there is probably multilple 12volt wires at the column... namely a thick red wire as well as a pink w/black... on some jeep and chrysler products these can't always supply enough amperage on just one of the wires to power the system correctly so u might have to share the loads between the two!!!!! ------------- there can be only one.......
Posted By: w87will
Date Posted: March 13, 2008 at 10:33 AM
hmmm. ok. Because right now I have one of the red wires from the satellite on the red ignition 12v, then the other red wire on the satellite on the Pink/black wire at the ignition switch. The RED / white wire on the satellite is just hooked up the the primary harness on the 5900 and the xk531....So the RED / white does put out the 12v to those sources correct? Thanks for the quick replys also, I appretiate it. I really need to get this thing figured out today.

if thats the wire i think it is...it powers the primary alarm functions of your die system... it needs to be connected directly to a 12-volt source.. not jumped in with other wires......connect that one directly to the ignition harness at the pink/black or the thick red.... if all your other connections are sound it will probably start to work then!!!! and your welcome!!!!

wait a minute.... if that is a thin RED / white coming off the primary harness goin to the alarm brain it's probably the trunk pop output....lol...... there should be a thin red wire comin off the brain for the 12 volt constant to actually powers the alarm brain itself...... check those connections......

if its thick RED / white wire coming off the satellite relay harness..it should be connected a 12-volt source as well....make sure the ribbon cable from the brain to the satellite harness is connected firmly between to two as well!!!!

little confused (just a little). So do I need the RED / white (+) 12v input from the relay? It says its the "connection for high current outputs". just eliminate that and hook up my 12v constant power inputs from the 5900 and the xk531 to the red and pink/black ignition 12v wires?

Date Posted: March 13, 2008 at 10:58 AM
BOOOOOO YAAAAAAAAA!!!!! u got it...that wire is used to connect trunk pops and stuff like that.... u got a jeep...no trunk...lol i was probably backfeeding the brain, causing it to ground itself out...... disconnect that wire... check your other connections and give it a rip!!!!!!! ------------- there can be only one.......

Awesome. Yeah I just tested with the dmm and im not getting anyting, lol. Thats def. why nothing is working, lol. Ima go fix it and keep you posted. I hope thats all I have to do

Not yet. I just went and bought a fuse holder/fuse for them. I should have it hooked up in 3 minutes.
Posted By: w87will
Date Posted: March 13, 2008 at 12:46 PM
ok got the wires hooked together. Now Im going to try and program the xk531 transponder and see if anything happens. It says to use a "jumper wire" to start the ignition. Would this just be a 12v wire that i would touch to the ignition wire?
Posted By: skee-weezy
Date Posted: March 13, 2008 at 12:57 PM
are u talkin about to program that module to the key????? if so... u don't have to do that crap... but u can if u want.... most of the installers i know just insert the first key...... wait about 15 seconds for the factory security light to go out..... remove 1st key...and insert and turn on the second key.... once again wait about 30 seconds this time...... most sentry system cars will now emit a chime after about 30 seconds..... now remote start..... if the car remote starts and then shuts off... it didn't program... u gotta do it all over again..... but if u wanna avoid the possibility of the system locking u out..... follow the programming directions and use like a 16-guage wire to jump power to the cars ignition from 12 volt constant or battery..... and oh yeah...don't forget to remove the second key completely from the ignition before u try to remote start... don't want that baby to see two keys at once..... ------------- there can be only one.......

Ill give both a try I guess. I noticed when I started my jeep with the key the engine/exhaust sounded "deeper" its weird. I dunno if thats good lol.
Posted By: skee-weezy
Date Posted: March 13, 2008 at 1:10 PM
was it with the key.. or with the remote start???? cause if it was the key u probably have a grommet in the firewall that isn't all way in and it's letting more noise into the car... and of course there is the possibililty that one of your sensors may have gone haywire from your jeeps 'recent' experience.... if this sound happens with the remote start u probably don't have all the correct ignitions and acc wires connected.. and if so.. immediately shut the remote start down as to avoid damaging your car!!!!!!

Actually the engine sounds ok now. But Everything seems to be working alright except my remote start. It will start it up then immediately shut down saying there is no key. I tryed following the directions for programing the xk531 transponder but when I use the jumper wire to start the engine it will not start.....it just turns the car in the Acc mode. If I can get that working I should be good. I still dont have my one headlight or my windshield wipers but ill figure that out later :)

those xk531 modules are junk..... find out where u can get a dei 556uw... or a code alarm uti at.... then either use one of your own keys inside that module... or grab a howard key for your jeep from your local locksmith.... then u can use the bypass and the two keys u have already to program that blank uncut key that will stay in the module...depending on where u live.... it may cost u maybe between 50 and 80 bucks for both the key and interface!!!!

Great. I really dont have the time to buy another module and cut this one out and put another one in. Im just having a problem "jumping" the jeep. I put one end of some 10gauge wire on the battery then I touch the other end on my ignition wire and no start, just into acc mode. Any ideas?
Posted By: skee-weezy
Date Posted: March 13, 2008 at 2:31 PM
i think u may have misunderstood the instructions my friend..... when u are entering into the programming mode and it tells u to jump power to the ignition....NOT TO START THE CAR!!!!!..... if u start the car up while the key is programming without the ENTIRE IGNITION SYSTEM powered up it's not gonna work.... all the want u to do it to jump power to the ignition long enough for the key to program.... after u get it to do so.... pull out your jumper...... and then start the car w/ the remote start.......if it gives u confirmation on successful programmin.... otherwise... start over again.....

hey....this is my last and final advice........ if u are not a installer for a living...... take it somewhere and PAY THEM to install it!!!!!! then if it breaks u can take it back to them and terrorize them...lol... if u ARE an installer..... CALL TECHNICAL SUPPORT ASAP!!!!! this is what they get paid to do...... i think i have helped u as much as anyone could without actually being there.... hope u get it all straightened out.... 1 hunid

Obvioiusly Im not an installer. I thank you for your help though. Helped alot. Ill just continue to move things around and if I cant get it to work I guess Ill bring it somewhere for someone to look at.
Posted By: techman93

I would advise not to "just move things around" until I get it to work mentality. You may cause more damage then you already have. I would say if you know you are not an installer, don't keep trying, get advice from a local shop. Usually if you ask around an installer will feel bad for you and give you some advice and even a diagram on what to do. It is kinda difficult explaining in chat on how to do something. I have about 10 to 15 years of hands on experience which can never be learned by reading how to install something. I will advise you get familiar with terminology used in installing, that will help you to understand diagrams and wiring instructions.
When you jump the ignition it is only powering up ignition system and will not start, and it shouldn't or there is a problem.
This is a post I made earlier how to program xk531 to a 2000 jeep grand cherokee
The viper should have a blue wire in a 4 pin connector on the relay pack. That will be the ground while running to brown wire on xk531. The purple wire is data which sounds like you have hooked into your odbII pin #2. The transponder will need to be programmed to the vehicle with 2 valid keys.
I have made a special relay box to power up ignition and fire the ground while running input to make programming easier for me on cars such as dodge, chrysler or when installing Audiovox remote starters.
To enter program mode you insert first valid key and turn to run or ignition position. Wait for the anti-theft light to go out and take that key out and insert second key. Do this within 5 seconds and turn to ignition or the run position and wait for light to go off. Leave ignition on and wait to hear a chime and then it will be in programming mode. Take the second key out of key cylinder. Then fire ignition within 5 seconds while holding the xk531 in front of the key cylinder and wait for the anti-theft symbol to stop flashing and go off (this can take up to 20 seconds or so). Shut ignition off and it should be programmed to the vehicle. Run the wires from module to around key cylinder and fasten in place with a cable tie or some good electrical tape (3m 33+). Hook up ground while running or also referred to as status output by DEI and then with all other connections make test for start. Make sure proper engine detection is being used such as tach or tachless. It should start up after this is done.
Factory disarm is not needed with xk531, the module will interface and arm on lock and disarm on unlock.
I also would advise not mess with program options. I did one the other day at a dealership 30 minutes away trying to get the driver door priority to work and it went into a lock out mode. In other words, it froze up on me. I had to drive back to my shop and have it reflashed to reset it and drive back out to the dealership to finish the install hoping it was going to work. It did thank god or I would have had to wrap and bury a key for that part of the install and change out the module to a xk03 flashed to the JDL format.

The wire I'm test'n isn't doin' what it's supposed to be doin'... I am so glad I printed that tech sheet, with the wrong info.
Do it right the first time... or I might have to fix it for ya

Date Posted: March 15, 2008 at 8:31 AM
Yeah I guess I worded it wrong. I would never just move wires around and see if they work, lol. Thanks alot for the tips and instructions. Very helpful. Im thinking my problem is within my last couple of wires I wired up, which were the tach, neutral safety and the ground while running. After I wired those up thats when I started having problems with the jeep. I might try to disconnect those and see if it starts to behave as normal. Then do more reseach and find the correct wires for them

the neutral safety wire is mandatory connection for remote starter to function. This wire goes to a solid ground along with main unit ground unless you want a shut off switch.

Yeah I had the Nuetral safety grounded with my other grounds. Today I tryed taking off the wires that seemed to cause my problems with the actuall jeep but with no luck. Still my Passanger Headlight is out, Speedometer doesnt work, Windsheild wipers dont work, Hood lamp doesnt work, also on the gauges the check engine, Brake, and ABS lights are on....... I dont know how to check relays but Im not sure if they would cause all these problems. Im going to see if a PRO feels like getting involved and checking things out for me. I really dont know what to do

Where would I find a diagram on all the relays in my Jeep and what they go to? It tells me what the fuses go to....but nothing about the relays above them. Also how to test if its bad or not. thanks.

now u have the rite idea... take it to a mechanic first... preferably one that specializes in electrical.... next stop should be to the local car audio shop.... best buy or circuit city should be able to handle installing your unit for u.... and the best part about it.... U DON'T HAVE TO WORRY ANYMORE WHEN IT'S NOT WORKING PROPERLY!!!!! just take it back..... another thing... completely remove the system from your jeep.... reconnect any wires that u cut..... disconnnect the battery... check all fuses.. replace any blown ones... then reconnect the battery... hopefully your body computer will reset and CLEAR ALL THE CODES!!!!!!!!!!! if not.. replace any blown sensors or bad components and take it to the pros..........

Thats what Im going to do. I have the alarm out and My jeep still has the problems. Ive checked all the fuses, they are good. But I need to find out what the relays go to and how to check if they are bad. If anyone has info on the 2001 grand Cherokee relays I'd appretiate it. If its not a problem with the relays Im going to have someone look at it then Ill get them to install the alarm also.

relays should be rite under the hood inside the box labeled 'fuse distrbution'... there may be more inside the car somewhere... but dude.. give up.. u have cost yourself enough... get it to a mechanic... at least pay him to diagnose it for u.. after that do whateva u want..... but u wont have to keep guessing at whats wrong..... ------------- there can be only one.......
