I am not sure about the problem, but if you haven't already purchased a new module, check out Ed Morad'* Ebay store or Email him. I am sure he can hook you up with one for much less then $700

It does sound quite odd though that LED tails would have any sort of effect on a module for traction control.... coincidence maybe?

i would hope its just coincidence.
its what the dealer told me.
unfortunately i already had the old module replaced and installed but like...im SO tempted to put the LEDs back in and see if it really was them.
if it blows out i could just say well...its still the same lights? haha, then theyll go searching for a new problem.
but i feel like something stupid happened. my dad tried to convince me that they fried the wires or something but still... like that dosnt make any sense? he makes it sound like i need a ballast for my friggen LEDs.
any more advice though?

I dont think that even if the LEDs did blow some wires (very unlikely), they they would be related to the TC

i assumed it was the traction control module since he mentioned traction control. maybe i was wrong.

I highly doubt the LEDs caused your issue. They draw significantly less current than a standard bulb, so the supply/demand issue should be non-existant. Also, when LEDs DO fail, they fail "open", and that'* usually if they were in over-current...meaning no resistors to bleed off spare voltage and current.

thanks for the replies...its helping me to a solution.

apparently "they" blew something related to both the anti-lock brakes and the tc. i guess it shut them both off? really doesnt make sense to me. i dont belkieve that it shut off the ab brakes but traction control was obviously off..even though i turn it off anyways...

what my dad said was something along the lines of:
"well the older bulbs when the electricity runs through them it stops at the bulb, with the LEDs it keeps going" i dont know, he actually confused the **** out of me but it still didnt make sense.

should i:

1) try to put them back in and see if it happens again..........(and if it happens again, i will take them out and just say it shorted out again)

or

2) just leave it as is and try to find some way to work it?

Saw your post and thought I would try to help as I've seen something similar to this before.

Your problem might be due to a resistance change between your LED'* and standard bulbs. This might have been what caused the damage.

I don't know exactly how this circuit is wired in your car without taking a look at a wiring schematic, but its just a guess.

I've seen one of my friends burn up half of his main harness under the hood from changing the OEM bulbs in his factory Fog lights to aftermarket bulbs.

The harness cost $1500 List, but he got off easy cause his father works for a dealership so it ended up costing him $700.
This was due to changing the resistance in the circuit, it was the difference between the OEM and aftermarket bulbs.

I would ask somemore questions at the dealership about what the exact cause was before you put those LED'* back in.

Sorry to hear about your troubles,
Regards,
Dutch
