I just purchased a new Viper 5901 and the IOM-Chrysler-7 bypass and after looking over both the Viper install guide and the bypass install I am very confused.

These install doc's contradict one another. One doc says that using the Chrysler-7 bypass takes care of the second starter wire and that I don't need to do the DirectFax doc 1084 with the relays and all but then the other install doc says I need to relay it with a 610 and 180 ohm resistors.....

Could somebody please clarify the install using this IOM Chrysler-7
a wiring diagram specific to these two would be even better.

Thank you.

I've never used a chrysler 7 but if it mentions MUX in the wiring instructions dont worry about the Directfax info. If it doesnt grab yourself a PKUMUX or a CHALL and you can definitely ignore the directfax

gotcha..... I appreciate the reply.

According to several I talked to on the Dodge Forum prior to buying anything they said the Chrysler 7 saved a bunch of wiring and stuff but these wiring instructions that came with it are truly a joke...

Very confusing.

Is there any chance somebody could help me with the IOM Chrysler 7 and a Viper 5901 going on a 2006 Dodge Ram.....

Specifically wiring the two together....   The DEI Doc's I have say I don't need to do the DirectFax 1084 with this bypass

Posts I've found on this website say I do...... Very confusing to say the least.

Thanks in advance.

Here's the IOM Chrysler 7 wires:

Green            - ground when running input    ???
Brown            - Lock input    I think I know
Blue             - unlock input I think I know
PURPLE / White     - Door sense output            ???
Purple             Can Bus Data Output          To WHITE/ Orange
Pink/White        Multiplex start output       To PURPLE / Brn
Pink             + Start Input   ???
BROWN / White      - Trunk Trigger (Not needed)
Red              + Battery       DONE
Black            - Ground        DONE

I am usually very good at this stuff however this one is really baffling me.... I can't risk or afford to damage my truck so I am asking for help....I greatly appreciate anyone who could help me...
I've just begun this install so I'm open to all input.

Thank you,
RamCrazy

Huge Help...I can't thank you enough!!!

I've got the weekend to get this installed so I have the truck for work Monday so I really appreciate your reply!

Ok new question....

Is there some kind of trick to programing this bypass to the truck...

I've followed the instructions that came with the bypass to the "T" close to 20 times now and time and time again it does not program.

I even followed the slightly different programing instructions in my Dodge Service Manual for adding additional keys and still nothing...

When I Remote start the truck, it starts and 3 seconds later it stalls with the security light flashing....

I'm assuming it is the bypass.

Thanks in advance for your help.

Here are programming instructions from an earlier post : https://www.the12volt.com/installbay/forum_posts.asp~TID~93511~KW~astroflex~PN~0~TPN~2

The last entry lists the steps required. It looks the same as adding a new key, but in this case the "key" is the bypass unit. Hope that helps.

Soldering is fun!

To verify its a bypass problem, you could try a remote start with a working key held against the ignition lock cylinder.

I must say that programing the bypass module for this vehicle is tricky!, the last one I did I had to take apart the bypass module and take off the immobilizer ring and hold the corner of the bypass module in the ring just to get it programed!

Thank you,

Yes, that is exactly what I have done like 20 times now..... I put first key in and turn on, when security goes out I put second key in and turn it on, I wait 30 seconds until I hear the chime indicating it's entered program mode....I then put the key with the remote taken out in and turn it on holding the bypass against the key/ignition cylinder. When I put the third key in (with the bypass along side), the Security light blinks and never stops blinking...According to my service manual it should blink for 30 seconds, stop and go solid, and chime indicating programs complete..

Mine never stops blinking on the bypass program.... I kept the key on for like 10 minutes and it continued to blink

I'm thinking that there may be something wrong with the bypass

it does remain running if I remote start it with a key in the ignition. Take the key out...even half way, and it shuts off.

try disconnecting the GROUND WHEN RUNNING (status wire) into the bypass, try programming then reconnect it.

Ok I'll try it.....but I was under the assumption based on the picture that is on the instructions that the bypass gets programed while completely unplugged....Just like you would if you were adding a key....Once the truck learns the bypasses transponder code then I plug the bypass back in..

I am holding the unplugged module up to the key/ignition.
From the way I understand these keys the transponder chip doesn't need a power source to function.

I can't find an IOM-Chrysler-7 install guide to verify this, but some of those type transponder bypass modules can only be programmed once to one vehicle. After that one time they can't be programmed again or to another vehicle.

Was the IOM-Chrysler-7 brand new in the box?

Maybe you already got it to program. Have you double checked you antenna harness connection and the proper wrapping around the key cylinder?

As a test, you could pull the guts out of a working Factory key FOB again and try starting the truck with the empty key and the IOM-Chrysler-7 module held next to it.

I have my IOM 7 install guide and it doesn't mention anything about only being able to be programed once.

I bought The IOM 7 off ebay and the auction listed it as new. It came in a vacuum sealed bag with an unused wire harness and instructions.
It doesn't appear to have been used before.

I tried to start it with a empty key and the IOM up against the ignition and it starts and immediately dies.... so It's obviously not programed.

I emailed the seller and he said these things rarely if ever go out...so I'm not real sure what to think at this point.

When you are doing the module programming procedure, do you get the chime and the flashing Security light after the second key is in the ignition position for 10 seconds?

Yes, actually the chime is closer to the 20 second mark but I do get the chime and flashing light.

I then remove the second key and immediately insert the key w/o the electronics installed and I place the IOM bypass right up against the key and ignition switch and turn it back to run....the light comes on solid for about 3 seconds and then begins blinking and remains blinking until I finally shut it off....

I left it on up to 10 minutes to see if by some chance it would program by no such luck...

I'm inclined to think I need to buy another bypass....I don't know...
all other functions (door locks, door triggers) that the by pass controls all work

An earlier post from jeremytravis might be worth a try. It's possible that your trucks antenna ring is not picking up the bypass modules' transponder during that last programming step.

That is quite possible.... I planned on trying his idea tomorrow. It rained here all day so I couldn't mess with it.

To clarify...The IOM should not need to be plugged in during programing correct?

Thanks for trying to help me. Appreciate it.

While I don't have the IOM-Chrysler-7 install manual, I believe that is correct. You are to hold the module ( with no harnesses plugged in ) against the stripped key that's inserted into the cylinder and turned to IGN, to program it.

If you open up the bypass module box you should see the little transponder (pill) inside. That area should be held closest to the trucks ring.

Ok thanks.... Yeah I took mine apart yesterday and the transponder is a black or charcoal looking "Pill" as you put it right? that's what I was holding up against the ring.... I'll try taking it apart tomorrow and seeing if I can get it to program....

I followed jeremytravis's method and still no luck. I took the ring off and took the board out of the IOM case and I held the transponder pill right up against the inside of the ring.... Nothing, it just continued blinking until I finally shut it off after 7 minutes.

I don't know what to think anymore.

Is there a limit to the number of keys that can be programed to the system?

I currently have three keys programed to my truck....The two original remote keys and one non-remote spare key so if one is ever lost I don't need to visit the dealer to program another.

Thanks

I GOT IT!!!!!

The instructions that came with the IOM DO NOT WORK....

The instructions in my Chrysler Service manual Do not work....

Here's what I did and it worked.

Insert 1st original key, count 5 seconds and remove.
Insert 2nd original key, count 7 seconds and remove.
Insert empty key with IOM next to Ignition ring and turn on ignition, the security light came on solid, flashed twice and went off. I waited 5 seconds and turned ignition off and restarted with IOM, it started and remained running....

IOM PROGRAMED!!!

What I've learned is as long as it's blinking it means that a non programed key/transponder is in the ignition.
When you turn on the ignition and the light comes on and goes back out in 2 or 3 seconds without blinking the key is accepted.

The Chime indicates it has exited program mode, Not entered it.

Thanks to everyone here that chimed in and offered assistance on this....It's been a very interesting experience and one I'd not like to do again anytime soon....Next time I'll let a pro do it... :-)

Ok new issue.....

The IOM is programed...I can verify this by starting it with a empty key and the IOM next to the ignition cylinder. Works every time..

My issue is now with the antenna or wire that came with the IOM which broadcasts the transponder code to the SKIMM ring...

It will start and remain running once, twice with no problem but then the third time I RS it dies with the security light blinking... If I go move the wire around the ring a bit it starts up fine.....

I'm including a picture of how I have the IOM antenna installed.... Please advise if this is correct. Thanks

I have since moved the wire inside the ring to see if that helps and still the same thing...

It Remote starts off and on.... each time it shuts back off the security light is flashing.

Usually its 3-5 wraps and placed on the key side of the ring. Try 5 wraps and go on the outboard ( key ) side of the skimm ring.

Thanks for the reply,

I moved it inside the ring this afternoon to see if it would help but it only has three wraps.... I'll increase the wraps to 5 or 6 tomorrow after I get off work if I have time... I didn't think the number of wraps made any difference but I guess it does...

Thank you.

Sorry about the delay in updating this post....

I increased the number of wraps on the IOM antenna to 6 and that solved the problem.

My viper install is complete thanks to the help from several of you, especially kreg357... Thanks you very much Kreg357.... You really helped me resolve these issues and I really appreciate your assistance.

Top of the day to all you guys!
