Turn Signal Defective

[ChronoMax]

This has started popping up. Very jarring warning. We check and right turn signal seems to be working fine. Warning goes away only to pop up randomly again. Of course it wont do it if we bring it into the dealer to take a look!

I had that issue crop up once, it lingered for a few days and then magically corrected on it's own. try waiting it out before running in for a service call.

Perhaps have a look at the unit's connections yourself (very accessible) - did you have the amber side markers swapped for clear? - if so (and actually even if not) make sure seated correctly - other than that it just may be a PCM hang-up that needs clearing with PIWIS at dealership.

I live in Central Florida where its warm most of the time and never saw the message as above. Drove up north for Christmas where it was chilly. First time I used the right turn signal in the morning I saw the same message as the OP. After the turn signal warmed up it was okay. Haven't seen it since leaving the chilly climate.

Havent touched any of that stuff. I think we will wait until its time to go in for the interior alarm monitoring sensor swap and have them look at this the same time. Bunch of other updates they will have to do at that point from what I understand anyway, so fingers crossed that will get it cleared up.

Did anyone ever have this diagnosed / fixed? Popped up again in https://www.taycanforum.com/forum/threads/turn-signal-defective-warning.15095/#post-230938

Ours did not come back after the (color icons on the PCM) software update last year. Could just be a coincidence and nothing to do with that, but so far so good. Hopefully this post does not jinx it and make the warning come back on tomorrow!
