05 Tacoma with 09 LED tail lights W/ ABS warning light and code (C1249)

[jcotoole]

Hello all,
I have a 2005 Tacoma and recently installed the new 2009 Tacoma led taillights (from my dealer) I was told they would work just fine. After install, my ABS light keeps coming on after a couple minutes. After stopping the vehicle, turning off the truck, waiting a minute, starting it back up the ABS light is gone, but eventually comes back on. I took it to a guy I deal with at the dealer and he put the code reader on it and code C1249 "open in stop light switch circuit" is present. The led lights come on and stay on, turn signals work, along with the back up lights ( everything is working as it should)

Here's what I am thinking: since it is an 05' and I just put in the 09' led tail lights, the computer is not getting the resistance of the brake light bulbs and it is thinking that both tail light are burnt out.

Can I put a resistor or something inline with the brake light wires to trick the computer into thinking that there is bulbs installed? Do I need to change the brake controller? Any other suggestions?
Any help would be greatly appreciated

O.K., now that I have been able to drive the truck for a week now, I have discovered that the ABS light only comes on the instant I turn on the right turn signal.

I drove the whole day yesterday without using the right turn signal and the light stays off. This is a great troubleshooting victory for me. Now I can narrow my search to the right tail turn signal instead of the whole system. I am assuming there is a short somewhere in the housing or the bulb. So I will have to check that out. If no luck, then I will replace the right rear tail light with the stock one and theoretically it should work fine. I will post my findings when I get a chance.

can't help you but i am following this post !
seems a lot are going to the led's

one question
if you just flip a right turn sig are all the leds lit?
might be hard to see?

The wiring is probably different on the 05 light compared to the 09. Even though the connectors hookup fine, it doesn't mean the wiring is the same. This was a common problem when most people purchased aftermarket red/clear lights for the 01-04 tacoma.

You will need a load resistor to trick the ECU.

Hi Jason,

Do you know which load resistor I will need for the new 09' tail lights? I am the gut who posted in the tundra solutions forum who has the 05' tacoma. I think the 50 watt load resistor will be too much. I would guess that I will need the 25 watt one. Am I correct??

Thanks for all your help!

I just read in the yotatech forums that if you put in the 09' flasher for the signals, then the abs light won't come on. Can anyone confirm or deny this? Has anyone done this? Any help would be appreciated.
