Topic: 2004 Caravan Remote start

I have installed remote start into a 2004 Caravan, and the remote start works. However, I cannot start the system with the key. I have used the TBKIII bypass for the sentry key, and have connected the yellow key sense wire to the Violet/Dark Blue wire coming off the ignition switch, which in my wiring diagram, shows as 'ignition switch sense return'. Any help in figuring this out would be greatly appreciated thanks.

Also, I cannot seem to find a WHITE/ tan wire in the driver's kick panel area for the parking lights. Is this wire near the brake switch and that area? And with the door locks, is there anyway to connect to the door locks without putting in a DRL? Thanks for any help.

Also forgot to mention, that when the yellow key sense wire from the TBKIII is not connected, the TBKIII constantly fires when the key is in the on position, and the vehicle is not running. Thanks again for any help.

connector 3, pin 21 @ The BCM in the drivers kick panel near the parking brake. It has 5 plugs in it, one 6 pin plug and four 34 pin plugs.Lock is negative trigger thru a 5.3K ohm resistor. Unlock is negative trigger thru a 2.0K ohm resistor. MUST use relays

You need to hook up the ground out when running wire to the TBKIII . Did you do this ??

Yes, I hooked up the ground when running output to the remote start. If I disconnect the yellow wire from the TBKIII there is no problem starting with the key, but then I lose all accessories. Where can I get these resistors? Also, if I make this setup, I should be able to get the door lock to work, right? One more thing, the wires with the resistors run to where? Thanks for your help.

What do you mean you loose all accrssories ? All I would do is return the TBKIII and describe your situation for a replacememnt unit or cehck the ground out when running wire. The TBKIII has only 1 trigger wire input and should only be activating when the remote start is activated. So check out the ground out when running wire to ensure that the wire is not getting a ground signal when not in the remote start sequence.

If I do not have the yellow key sense wire connected from the TBKIII, I do not have any accessories. Actually, I do not have accessories after inserting the key and turning it to the on position. But once I connected the yellow key sense wire, I got my accessories with the key in the on position, but now cannot start my vehicle with the key. It will start, but then turns off as if the Sentry key is not working properly.

How did you hookup the violet/brown starter 2 wire? If you don't use a diode in the circuit you will lose your accessories as described. It should be hooked up as follows, note the diode which is NECESSARY!:

Also I'm showing the key sense as light blue, but not sure on this I don't usually hook them up it shouldn't be necessary. If that seems to be the problem with the install I would say something else isn't right as it shouldn't make any major difference. Also if your using the same wire for the TBKIII igntion out and the starter 2 wire, you need 2 diodes.

For the parking lights just look at the harness coming off of the headlight switch itself real easy to access.
WHITE/ brown = (-) through a 5.3k ohm resistor.

For locks use the info Jeff posted above. Look at the bcm there are 4 plugs vertically. You want the second down from the top or the 3rd up from the bottom. (same plug either way)

Good luck,

Mike

Mike, thanks for the help so far. I have used a diagram from Jeff regarding hooking up the violet/brown wire as pictured here. I also don't see any 3rd ignition wire, where would this connection go to from the relay? Thanks for your help, this is answering my questions.

With regards to the door locks. If using the diagram that Jeff provided, do I need to connect the (-) or the (+) wire to the resistors? Thanks again.

The locks require a negative trigger and if your unit doesn't have a 3 rd IGN output, just use the ground out when running wire instead.

The Ignition 3 (-) out is the same as an active out (-) or some units call it a status out (-). Or it should be the same as the ground out when running wire that you are using for the TBKIII. Are you connecting BOTH the TBKIII AND the relay for the violet/brown to the ground out when running wire? If so, as mentioned you NEED 2 diodes to isolate the two. The diodes are not optional and if not used you lose your accessory.

Also the second starter needs to see a ground through a 180 ohm resistor. The diagram you posted shows it giving it straight 12volts positive, without a resistor. I'm assuming Jeff just gave you that diagram as a guide to hooking up the second starter wire to get an idea of how to wire the relay.

If using the diagram Jeff posted for locks, connect it exactly as shown that diagram is fine. You connect the resistors to pins 30 as shown in the diagram and MAKE SURE pins 87 both have ground on them. What ever you do, do not connect 12volts to those resistors. By the way in the diagram where the red wire crosses the yellow resistor wire, that is NOT a connection.

I always recommend the diagram below for resistor door locks for a few reasons:

1. Using the positive locks from the module saves the need to put an fuse inline. 99% of units out there will have flip flopping +/- locks.

2. Aside from the lock wires themselves being positive, there is no 12volts being connected to the relays meaning very little chance of you wiring them wrong and throwing 12volts into the negative lock wire..

Either diagram works. Good luck,

Mike

Thanks, this has answered everything except one question. You have the door lock wires from the alarm module as being positive (+) however, I have either connection on my alarm module, and I know the caravan has a negative (-) door lock system. Should I go ahead and just use the positve wire and not worry about using the negative.

It depends what diagram you want to use..If using the diagram Jeff posted, set your door locks on your module to negative. If using the diagram I posted, set the door locks on your module to positive. Pins 30 and 87 are the two pins that are going to be connected to each other when you hit lock or unlock on the module. So whatever you do, DO NOT put 12volts to pin 30 or 87. That is pretty much the only thing you could do that could actually damage anything. Any other wiring mistakes the setup just wouldn't work.

The lock wires from the module are just to activate the relay they have no bearing on whether the locks are positive or negative since your using relays. When the relays are activated, pins 30 and 87 connect sending whatever you put to pin 87, through your resistor to the lock wire. As you see from the 2 different diagrams in this case these 2 pins are interchangeable so don't get confused as to why Jeff lists it one way and I list it another. Bottom line wire it up exactly as either diagram shows and your set to go. By the way on my diagram pins 30 and 86 on both relays are all going to go to ground. Not everyone is familiar with the ground symbol I used in the diagram just thought I'd mention it. Hope it helps,

Mike

One more question. When connecting the ground when running from the TBKIII and the relay for the 2nd starter wire, how would the diodes be placed here. Thanks again, as you have answered everything guys. Will definately be helping this site out. As I am overseas in the military, this is the only place to go for help considering that Remote Start is illegal here in Germany. Thank you so much guys.

The cathodes (stripe side of the diode) will face the R.S. module.

Hell yeah buddy!!!

Thanks again for the help guys. I knew when I was having difficulties I could count on you guys. I checked this place out before I started installing my system. Wasn't sure what I was getting into, but I must say it is not near as bad as I thought it was going to be.

Just curious if anyone could help me get my hands on the following:

5.3k ohm resistor x2

2.0k ohm resistor

180 ohm resistor

Thanks,

Derek

Radio Shack's the best source, if you have a store nearby. If not you can use their website. The resistor values usually have some tolerance in them (e.g. if a resistance is within 5% it will activate the desired circuit); so you don't need to find a resistor of that exact value.
Also, you can combine resistors to get the needed value, but it'd probably be easier in your case to just find the right values alone.

Well the only problem I have with running down to the nearest Radioshack, is that is about 5,000 miles away considering I am overseas in Germany. I was hoping someone on here might be able to help me out. I know the math doesn't add up, but would a 2.2k with 5% work for a 2.0k? That is the only resistor I am having a hard time finding. Thanks again everyone.

No this will not work because the tolerance will be +/- 110 ohms. What you can do is take a smaller resistor and wire it in parallel with the 2.2kohm resistor to drop the resistance. Using a 150 or 200 ohm will drop it within range of the required amount.

So for the 180 ohm connection, would a resistance of 175-6 work? That is running 2 resistors in parallel and I have it there. But on the diagram it says to run between 180-210. Thanks again.

BTW, did you ever take care of the "No Accessory" problem you posted earlier?
Here's a hint I discovered the hard way, whenever the Pink/White ignition wire sees a load before remote starting, say for example a coil of a relay, it adds this resistance value to the value in the key barrel. What you get is a vehicle that starts just fine but the accessories don't come on! posted_image

This is why we use the groundout and the crank signal when doing the second start relay rather than tapping on to the ignition wire. posted_image

There . . . now you know.

Everything is now working the way it should except the door locks and the parking lights. The only reason they are not connected is because I don't have the resistors for them right now. Also, just curious which wires are for the door locks coming off the BCM. It has the seperate door locks for the driver and the rest, but I am not worried about hooking up that feature. Thanks again guys.

Posted By: chriswallace187

For the doorlocks, you could try using the 2200 ohm resistor. I've found that even though most wiring info says 5% tolerance, you can go outside that range a bit and it will still work properly.

As far as the actual doorlock motor leads, they are also run off of the BCM. I know they are slightly heavier gauge wires and I seem to remember them being tan with stripes and in the top connector at the BCM. There should be one driver's unlock motor lead, one passenger doors unlock motor lead, and a lock motor lead for all doors.

Need a little bit more help with my 2004 Caravan. I noticed tonight that while pressing the brake, the left brake light acts like a strobe light somewhat. What I mean is that about ever 3-5 seconds, it will slightly flash one time. It does not go all the way out, but just makes a quick flash, and it is only the left side, not the right. Also, when I arm the alarm, it says that a door is open, but there is no door open.

Also, I am curious at how to hook up the parking lights. Do I need to use a relay, or can I just tap into the parking light wire (WHITE/ tan) at the light switch and put in the proper resistor. Thanks for the help.

Parking Lights: WHITE/ brown (+) In the driver’s kick panel. THere are (2) WHITE/ brown wires so each must be tested to ensure proper connection.No resistor's or relays required for this connection.
