Hi everyone,

As some of you know, I've installed a Viper 5101, with an Omega vehicle interface in my 2003 Jeep Liberty. Every things works great except the parking lights. For some reason they don't seem to work at all. They don't flash when I lock/unlock the doors, and they don't come on during remote start.

I have the H1/11(white) parking light output wire soldered to the pink parking light input wire on the interface module. I also have the parking light polarity fuse installed in what I think is, the postive position.

The reason I say "I think", is because the module is mounted in a location where it's very difficult to see. According to the installation manual the fuse should be installed in the two pins towards the center of the module. Can anyone verify this for sure.

I haven't had a chance to test for power coming out of the remote start module, but that's my next step. I'm curious if anybody has an suggestions or input.

The only manuals I have been able to find for the CHDL4 module do not show a parking light input. The pink listed is for door trigger. Do you have a link for that module? I would love to take a look at it.

On Chryslers I usually just do the relay/resistor install for parking lights. Simple enough to do and reliable.

I haven't installed a 5101 yet but I think you can just install a 910ohm resistor across the jumpers in the brain and hook the white wire to the vehicle's parking light wire? I might be wrong on this.

Without the parking lights I never know if the vehicle is running or not since I'm often too far away to hear the engine or see the exhaust from the tail pipe.

If I can't get it working with the module, I may go with the relay/resister method.

Must be the installation sheet they sent me with the module was wrong then too.

Do you guys have any suggestions where I can find the resisitor I need?

Judging by the Ohm's law calculator on this site 1/4 watt 910ohm resistor should do the trick.

I'm a bit confused now. I've been doing some research on which resistor to use. The DEI vehicle wiring chart I've got says to use a 910ohm resistor, but Bulldog security says to use a 1000ohm resistor. Maybe I'll have to buy both and see which works. https://www.bulldogsecurity.com/diagrams/extrainfo/diagrams/14301_LIBERTY_JEEP%20LIBERTY%20PARKING%20LIGHT%20DIAGRAM.pdf

omega - 1k ohm resistor
fortin - 1k ohm resistor as well

Here's another question. Even if the parking light input wire was eliminated in new versions, are the parking lights still functional through the module?

I think I'm going to email Omege support on this just for the heck of it.

This is confusing. I went to Omega's website and looked up the installation instructions. The instructions on their website are identicial to the ones I received with the interface module I have. When I go to the databus integration compatibility portion of their website, it says "Developed by BypassKit OE integration", which leads me to believe it's the same exactly module BypassKit sells.

To make matters more confusing, BypassKit's website says;

PRODUCT DESCRIPTION:

Data bus interface control & transponder bypass combo: Lock/Unlock, Rear hatch unlock, OEM security arm/disarm, Park lights, RAP control & Transponder bypass: RF override through induction using loop antenna (Transponder included no key required)
Features:

compatible with any remote car starter
compact design easy to mount
compatible with manufacturer's anti-theft system
maintains integrity of manufacturer's anti-theft system
compatible with manufacturer's security and convenience functions
maintains integrity of manufacturer's security and convenience functions
no need for additional resistors or relays
easy programming
no extra key required for operation

...but then in it's own installation instructions it clearly states;

Pink wire (parking light input) has been removed.
A relay & 1000-OHM resistor is needed to activate the parking light circuit of vehicle.

Somebody needs to get their act together.

I emailed Omega via their website. I'll let you know what I get for an answer.

I'm guessing you guys are correct in saying I'll need to pick up a resistor. I'm glad you guys know what you're doing. :D

Instead of using the chdl4 for controlling your parking lights, why don't you just use (H1/4 & H1/11) for the parking lights. Locate you light switch wire, should be light GREEN/ orange and then cut it in two. Then connect the WHITE/ brown (H1/4) to the switch side and white (H1/11) to the other side of the light.GREEN/ orange wire. Put a 1000 ohm resistor and plug it in between the middle pin & the pin closest to the side of the module (brain) & be done with it.

See page 15 of the 5101 install manual for detail

Did your 5101 come with a 451m? If so there will be a pack of resistors in there and 1k ohm will be in there. There is a chart with band colors to identify it and also put it to a meter to verify. You can do as 12volt stated and solder it in to the parking light fuse holder instead of the fuse.

dasbogie, my 5101 didnt' come with anything. Heck, I didn't even get the installation manual & owners manual. I had to download those off the internet.

moonliter, I understand what you're saying and I understand the instructions in the installations manual. I just have one question. Is isolation of the parking light switch necessary? Or, can I simply put a resistor in the rs module and connect the white H1/11 to the light GREEN/ orange wire?

I know I'd probably safer to isolate the light swtich.

as long as it doesn't have autolamp and left at OFF then it shouldn't be an issue. Yes, you can replace the fuse with the resistor and install it in the pins as I mentioned in my previous post.

What exactly are you referring to as "autolamp"? Lights that automatically come on?

It doesn't have anything like that. It doesn't even had daytime running lights.

Date Posted: February 21, 2010 at 2:57 PM

That is correct ! If you don't have it then it shouldn't be an issue. Just connect the white wire to the light.GREEN/ orange and 1k ohm resistor.

Would anything funky happen if the parking lights were on at the switch and the doors were locked(flashing the parking lights)? Basically this would act as though there were two 1000ohm resistors wired paralell. Would the BCM just ignore it since it's not a recognized resistance value?

I think something funky would happen My Post 2004 Liberty door locks
I think the parking light circuitry has a major problem in this bypass which is why it was removed because as soon as I tried to unlock the doors one time with the parking lights on my front door locks and tailgate lock completely quit working. Rear doors are fine.

The instructions that came with mine said positive to the pink wirse gets parking lights and it did up until I tried to unlock the doors which would have flashed the parking lights. Now I do not have door locks even from the switch inside the car.

I am beginning to think I messed up the Body Control Module with this and that is a $650 fix at the dealer. Any more thoughts on this would be appreciated

I think I'm going to isolate the switch just to be on the safe side. After all, it's just a matter of one more wire.

Omega's tech support said...

"The module has a Pink wire with a white stripe (tracer). Where was that
wire connected. It is the parking light output to the vehicle."

If this is the case, then perhaps it should have been connected to pin 5, instead of pin 9 like the instructions indicate.

Unfortunately, the instructions with the module didn't give any indication what the wire was used for.

moonliter,

I have a question. Regarding multiplexed wires. Do I risk damaging the BCM if an accessory, such as the parking lights, are on and then ground is applied through second resistor? Basically I think it would be just as if two resistors were wired in parallel, thus putting out a completely different resistance than what is intended.

Tech support at Omega said I need to connect the pink/white(parking light output) to the light GREEN/ orange at the headlight switch which is in total contradiction to the installation instructions the interface came with. However, it makes more sense logically. My concern, however, is as stated above. What if I have the parking lights on, and then I unlock the doors causing the brain of the remote start unit to pulse the parkiing lights.

Just for the record, I do not plan on wiring the parking light though the Omega interface. I'm just going to wire the remote car starter directly into the parking lights utilizing a resistor according to the directions in the installation manual. I would just like to know about the mulitplex wires for future knowledge.

Thanks

Here is what I am going to do since I am 90% certain I have messed up the BCM. I am going to as another reader suggested pull the fuse out of my parking lot output wire and replace that with a 1000 ohm resistor then switch the remote starter to negative out put an then connect that to the light GREEN/ orange wire either at the BCM or headlight switch and I am going to do this while the bad BCM is still in and confirm the parking lights work with the remote start. Just to be on the safe side I was reading the manual to the jeep and you can program the RKE system to flash or not flash the parking light with the door lock and unlock you can also program the horn honk on or off. This is a owner programmable thing easily done with the fey fob I have already turned off the parking light flash with the door lock and unlock. It will be this weekend though before I get back to the wiring.

Okay. Just for entertainment, I removed the pink/white wire(parking light output from the CHDL4-PK) from the light GREEN/ orange wire at pin 9 of the BCM C2 connector. I then connected it to the light GREEN/ orange wire at pin 5 of the same connector(Headlamp MUX).

Guess what? When I lock/unlock the doors, the parking lights & the headlights now flash, so it looks the installation instructions were definitely wrong. Being that the headlighs flash with the parking lights, I think the CHDL4-PK is putting out the wrong resistance value.

Neither the parking lights, nor the headlights work when the vehicle is remote started. At first I thought it was because the polarity fuse wasn't installed in the Viper 5101 brain, but even after I installed it, they still don't work. I think I have it in the positive position. It's plugged in the two pins closest to the center of the brain.

Well, I quickly figured out that the pink/white wire is NOT the parking light output!!! It IS the factory alarm disarm. posted_image

If I decide to to wire up the parking lights, it will DEFINITLEY be without the CHDL4-PK interface. Furthermore, it appears as if Omega's tech support doesn't know how these interfaces work, let alone which wires go where.

I don't think I'll be purchasing another Omega product anytime soon.

I switched my parking light output to neg out instead of positive and put a 1000 ohm resistor in the line and connected it to pin 5 C2 light green orange and my parking lights work. Need a resistor go to radio shack I got a 100 pack assortment for 6 bucks. I still have a door lock problem but I am going to take it to the Jeep dealer next week and get them checked out. after some reading I think they may just need reset.
