2017 Model X, no left turning signal on dashboard while turning lights are on. enhanced autopilot can not engage left turn.

[Kelvintoronto]

I have a model x 2017, and have the problem of left turning signal on the dashboard and autopilot.

While I push to left turn, the exterior turning lights are on, but there is no any turning signal or sounds on the dashboard. And I can not engage the left turn of enhanced autopilot.

Any suggestions? Thanks

Check service mode for any error and diagnostics

Check service mode for any error and diagnostics

I will access the service mode to see what information I can get.

In the meantime, I contacted Tesla and as told, they need to do a Low Voltage Circuit Integrity Check. No idea what it is and whether I need to pay big amount for the electronic circuit board. Do you have any ideas about the Integrity Check. Thanks.

Before cars were computers, turn signals lighting solid or flashing quickly was an indicator that one or more bulbs were burnt out. Perhaps this is still the case with the LEDs in modern vehicles, as those would be part of a low voltage (12V) circuit (same as incandescent bulbs would have been, though there was no high voltage circuit in the past). If you can see that one of the lights is NOT lit, there is a chance it is the problem. However, unless you are going to attempt to resolve the problem yourself afterwards (by replacing whatever assembly houses that light or going full DIY to rebuild said assembly), I suspect they will likely still charge for this service. I also suspect they will suggest, accurately or otherwise, that said light might not be the issue.

Except he said the exterior lights were working fine. Just not showing on the ICD, and silent. <puzzle>

So what you are telling me is that "on" means flashing? Guess I need to update my dictionary...

ETA: And not only does "on" apparently mean flashing, but apparently it means flashing at the normal rate. That is a pretty powerful new word.

ETA2: And apparently it also means that every single relevant light was closely inspected to confirm this. I'm so sorry my posts aren't helpful because I don't know what things like "on" mean.

sorry that my problem description is not accurate. Yes, exterior lights are working fine, but not showing on the ICD and silent.

Nah, I'm sorry I can't help with that and glad someone else could understand what you meant.

Did you end up finding the cause of the problem or did Tesla say when you took it in?

I went to the SC, and replaced the Front Harness ( the cable). Total cost is $635.

Did replacing the front foglight and sensor hardness fix the issue? I have the same problem, exterior turn signal are on but the interior car screen show no blinking and sound.

Mine is the problem is harness cable. After chaning the cable, there is no problem now.
