My car loves the three lights: VSC TRAC OFF and ABS lights. Installed my Rostra cruise control tonight and after everything was hooked up, I tested it out. Btw, Gray cruise wire is connected to violet and white wire in 2nd ECU cluster from passenger side. AND green cruise wire is connected to black wire in far passenger side ECU. I have yet to test with a Volt meter. I plan to do this tomorrow.

When car is running and cruise is turned off, NO LIGHTS. However, when I turn on the cruise, the VSC, TRAC, and ABS lights all go on. NO CEL.

AND my damned oznium.com Third Brake Light turns on (at about 50% brightness; 100% being when brake is applied). Also, my LED tails turn on very faint (25% brightness; 50% being when headlights are on; 100% being when brake is applied).

I had this problem earlier when my trailer lighting harness and oznium TBL was having problems causing my car to throw the cluster of lights. Here is my thread about that: https://www.scionlife.com/forums/sho...d.php?t=197935

Seems as though something with my cruise control has caused a connection with the lighting! ITS AGGRAVATING!!!

Oh and also, the cruise control does not operate whatsoever. The green light on the cruise switch does light up when turned on so I know the unit is receiving power, but there is some kind of problem with the cruise itself. I dont know if the cluster is causing the cruise to completely fail or not.

I think the 2006.5 might have something to do with it. I think the wiring might be different in a 2006.5 vs. a 2006. My xB is 2006.5.

Any help would be appreciated!!!! I highly doubt taking the car into a standard car audio place would know what the heck is going on. I need your guys' expertise yet again. Thanks.

*UPDATE**
So today is my diagnosing day. I have taken everyone's feedback and I plan to either add a resistor to my TBL or wire my TBL with an original factory bulb.

First, I wanted to adjust the slack on the cruise throttle wiring. I have about 3 inches of slack and I cant for the life of me adjust this snap-in threaded connector to adjust the slack. The plastic piece will not budge and I think that could maybe affecting the fact that the cruise isn't working at all.

Rostra tech support has not emailed me yet.

Update: Ok just figured out that you have to use pliers to crimp the block side of the snap in adapter and then that comes off of the entire bracket. The entire snap on unit is one piece, i thought it was two.

Update: Just went to Radio Shack, gots somes T Taps for the TBL and OEM TBL combo pack. Just tested cruise control with OEM TBL, AND GREAT NEWS! NO CLUSTER. TOWSTER LIKES OEMness but his owner disagrees.

Good Update: Seems as though everything electrically was connected last night and the only problem was the slack on the throttle cable. I adjusted the slack and the cruise works like it should! Plus no VSC ABS and TRAC lights if I have the OEM TBL. The brakes deactivate cruise as well as shifting to neutral. Quite excited, now onto Oznium's damned TBL. Please Beautiful LED TBL, be nice...

TBL Update: So this is the scenario: Factory wiring -> Oznium TBL Connector into factory plug -> T-Taps along Oznium wiring to attach OEM bulb -> Oznium TBL. With this scenario, both the oznium and OEM light up when brake is depressed, BUT when turning on Cruise, it still throws the cluster and original problems continue. I will now try an alternative.

FINAL UPDATE later that day: So here is the scenario that finally worked out and allowed for my cruise control to operate without problems. For the third brake light: Factory wiring -> OEM bulb into factory plug -> Homemade wiring connecting Oznium TBL to bulb connection -> Oznium TBL.

It works without problem and I used electrical tape to seal the connections. Both the OEM and Oznium light up when brake is depressed. I will post a Youtube vid showcasing my mickey mouse job.

Now then, Utilizing the above scenario AND also reconnecting my trailer wiring harness to the taillights, I through VSC, TRAC, and ABS lights and my car functions the same as listed in my older thread linked above. I will have to drive without the Oznium TBL when towing... so sad. So the problem ultimately was the Oznium light, but at least the computer is thinking that it is fixed!

Thanks for all the help!!!

If those links aren't enough, Rostra tech support can talk you through troubleshooting your installation, or refer you to a factory-approved installer.

 

Yeah those links are about 2006 VSS and NSS wire tap locations which I have already done. 2006 is different and I have tapped into the correct ones.

I contacted Rostra via website, hoping for a response. I will keep you posted. Thanks Sentra.

 

Did you try re-installing the factory third brake light?

As much as I want to use my LED oznium third light, it still sits in the closet for the troubles it caused me.

At least you could eliminate the light as the culprit.

 

I installed mine a day before leaving on a month-long cross-country trip, & didn't have time to debug it. Mine's a 2006.5, too. A Rostra-approved installation shop fixed the misconnected VSS wire for $75,but I never figured out whether it was my error or an error in Rostra's diagram.

Call Rostra tech support. They only have one guy, & he's pretty helpful.

 

The latest installation manual on Rostra website seems to be correct as far as the color and wire locations for 06.5. Most likely your Cruise Control would be working if you didn't have LED stops all around.
Try wiring a regular small 12V light bulb into the brake light circuit. Basically one lead to the ground and the other to the Green/Red wire out of the brake pedal switch. It's just an experiment- it may or may not work but it's an easy thing to try. Otherwise you may have to build a transistor based interface or install a separate add-on brake switch just for the cruise.

 

Multiple updates, cruise control operational, although Oznium TBL causing cluster.

 

Final update with solution to problem.

 

Great!

 

I just want to understand this completely.
This: Factory wiring -> Oznium TBL Connector into factory plug -> T-Taps along Oznium wiring to attach OEM bulb -> Oznium TBL :did not work because the dash lights came on as soon as you turned on Cruise.
This: Factory wiring -> OEM bulb into factory plug -> Homemade wiring connecting Oznium TBL to bulb connection -> Oznium TBL :allowed Cruise to work without problems.
What's the difference between both set-ups?

 

This is exactly correct. Here is the difference (I know the wording is hard to understand and I am uploading a Youtube vid to show it)

The first scenario: The Oznium TBL adapter was plugged into the bulb slot. The bulb was then T-Taped into the Onzium TBL wiring leading to the actual TBL itself.

The second scenario: The actual OEM bulb was connected to the bulb slot. Wiring was then fed into the bulb slots to give power to the oznium.

I will be uploading a youtube video tom

 

Like I said, that's the reason mine just sits on the closet floor. It's so sad to have such a beautiful light be just a dust collector.

Good troubleshooting job!

 

The problem is the efficiency of the LEDs in the Oznium TBL. All you have to do is wire a resistor into the TBL circuit, and the AT TC slippage & cruise control problems will go away.

 

Does that mean that at first the bulb was connected in series (didn't work) and then when you connected bulb and Oznium TBL in parallel and that made everything OK?

 

Yeah, but I only tow once a year, I guess what I will do is disconnect my TBL altogether when I tow. No big deal... I just wish the product was developed in a manner that doesnt cause problems.

 

Well with my homemade solution, the problems have gone away. I have no idea what resistor I would need and how I would wire that (I know very very little about electrical wiring concepts). I went to Radioshack and I was so overwhelmed by all the different watt/ohm choices for resistors that I decided to just wire my oznium and oem lights together.

 

Reactor, I will upload the video today showcasing what I did, words cant explain it justly. Gimme a couple hours.

 

voila

But LED already draws less current than reg bulb, so how would resistor help if it can only decrease current further?
The problem is not with Oznium TBL, it is with the way Rostra monitors brake pedal position. It wants to see Ground when the brakes are OFF. When you have replaced stock tail lights and TBL with LED's you removed Ground from that side of the circuit because LED's are diodes and they do not let the ground through. That's why you need a dummy light bulb to let the ground pass to the wire that Rostra is hooked up to.

 

I do have LED tails, but they dont throw any lights. My LED tails have been installed for the last 2 years, and I have never had any problems with them. Im just glad that for now everything is working...
