Im currently in the process of LED cconverting all of the light in my 2010 camaro ss/rs and i recently installed 4 all new led taillight bulbs and ever since when i go to turn on my signal it blinks rapidly and says to check my right and left turn signals, but when i turn on the hazers and look at the back to see if the light work they all turn on and work fine, is there any fix to this? Thanks!

if you have not found out already you have to install a resister in line cause the LED dont back feed as much volts so its the cars way of telling you your bulbs blown.

I get three normal blinks, then hyper flash, and I don't care. I live with the warnings.
I will not use load resisters. I use LEDs for the energy saving benefits. Load resisters
put the current draw back up to incandescent levels, so what's the point...

There is no FEED BACK of voltage. The BCM does not see the proper load on the
circuit, so it thinks the bulb is out. Feed back suggest current flow in the opposite
direction, and that does not happen, even with incandescent bulbs. It's just
a current sensing thing.

LEDs that say "Can Bus" just have load resisters built in. There is NO actual
communications from the bulbs to the BCM, LED or otherwise. The CAN BUS
monitors the output current to the bulbs through the BCM, and when too low,
or none at all, it sets the warning.
