Default Turn Signal Hyper Flash
My left turn signal on my '23 HTC now goes into hyper flash and the DIC says "Check Left Front Turn Lamp". Has anyone else run into this and what is remedy?
Thanks in advance for any input.

Well, thanks for that!
From what I've read in other threads, the turn signal is LED and fixing requires replacing the entire unit.

There is a module behind the headlight with wiring connectors in front of the wheel well liner. The problem may be there, but most likely a problem with the LED in which case the entire headlamp assembly needs to be replaced. My drivers side DRL in the headlight was defective and stopped working after 200+ miles. The dealer ordered a new headlight and had it the next day. Had it installed and no problem since. Make sure the dealer had good techs. The front bumper needs to be removed to replace the headlight.

So this is "engineering progress". Probably at least $3,000 to replace a turn signal bulb. Just wonderful.

Update - this was self inflicted. When searching for switched power in the fuse box, I inadvertently left #47 out. It's one of the exterior lighting module fuses, which handles both the left front turn signal and the passenger tail light, both of which were out. Put fuse back in, works as it should.
Thanks to those who offered input.

The first question to always ask is "What has recently changed before the problem occurred?"

It's not a bulb...it's a light emitting diode (LED). Several of them, actually.

Cheaper to re-install the fuse that was removed and neglected to be put back in.
