Ultrasonics broken funny, anyone seen it?

[Sophias_dad]

Got the car back from the SC last Tuesday, and found that auto-lane-change had stopped working. A while later, I noticed that the ultrasonic range sensors weren't working, which I assume was causing the auto-lane-change issue.

But here's the rub.... the sensors for the FRONT of the car work in the morning, but only when the car is in REVERSE gear. Pretty much worthless. The sensors in the rear of the car don't ever work(even in DRIVE). And after even a mile of driving, the front sensors stop working completely.

I've got a ranger appointment to fix this, but if its a known issue I might be able to fix it sooner.

I've already done both a soft reboot and power-off reboot, to no avail.

Thanks!

I think I’m having this exact issue at the moment... noticed the “waves” for front when pulling out of a garage spot this afternoon.... hmm. My auto lane change and navigate on autopilot don’t work. Hasn’t for at least a week now.

I'm pretty sure there's a failsafe in there to disable auto-lane-change and navigate on autopilot if the sensors aren't working.

I have a ranger coming to visit on Tuesday, and I suspect they'll need to arrange it to visit a SC for the real repair. In any case, I'll report back what the cause was.

What software version?

What software version?

2018.50.6

Like I mentioned, it started when I had the car at the SC about a month ago, so I doubt its a direct result of the particular SW revision. That said, the front ultrasonics only working in reverse is a pretty good sign its SW related. But that doesn't explain the rear ultrasonics being completely off.

As I think about it, I think I saw them updating the SW while it was in the SC... so it could well be busted SW.

Maybe they are testing an early dev version of the new FSD software on you. Next is regulatory approval.

Sounds like I need to continue to keep my car out of the SC until Elon bends them to his will which he says is his #1 priority this year.

I have my appointment to have this all checked out on Wednesday afternoon... Crossing fingers here.

Service ranger was able to fix it. Found that one of the(or maybe the only) connector to the PDC(Parking Distance Control) unit was not fully inserted. Sounds like the PDC lives in the trunk somewhere, based on reports of where he was poking around. Betcha a parts list search could find it quickly.

I'm gonna open another thread for a windshield washer issue the SR was unable to fix. It wasn't on the official list of issues, but he looked at it anyway and was unable to explain it.

In any case, the ultrasonics are working fine now, and I have my auto-lane-change working again!

Not inserted correctly from delivery or that it came loose at some point? Dropping car off Monday after a botched service spot this past Wednesday... grrr

Sorry to say it was almost definitely a result of the service. It worked before service for sure, and auto-lane-change did not work after service(literally on the drive away from the SC). The fact that the PDC wasn't working was recognized shortly thereafter.

Interesting. Thanks for the update. Tomorrow I'll hopefully find out more... This, for me, just randomly popped up outta no where but very similar problems.
