LTA / Radar / Cruise Control Trouble Codes - Investigating

Started as a normal day...

I dropped my truck off for its 5k mile service today. I mentioned my issues with the intermittent LTA / Radar / Cruise Control warnings and my random wireless CarPlay connectivity issues when I dropped it off. To be honest, I haven't thought much about those issues because nothing has happened in about 3 weeks.

Fast forward 5 hours and I get a phone call at work. They pulled the codes from the computer, and they see a bunch of failure events in the history that have caused them concern. I'm picking the truck up today after work, but they want me to drop it off with them the middle of next week so they can spend a few days investigating the issue(s). Apparently, they can see events that in the computer history that did not pop up a warning light on the dash. I'm sure this is by design.

I'm not an alarmist. I'm not even all that upset. They'll fix it and it'll all work out. I'm just sharing because I know we've had a few threads on the forum about LTA / Radar / Cruise Control codes popping for folks. We'll see if I have the same DCM issue as some others have experienced.

We'll see what shakes out. More to come as I find out more next week.

 

I just got mine 1794 last week.
Here are a few issues and I called Toyota Support, they couldn't help me to troubleshoot this issue over the phone.

-Set LTA "Off"
-Set Sway "Off"

Every time I restarted the engine, sometime LTA is back "On" and Sway is "On" again every time.

I can't turn the Sway mode "Off" permanently :-mad:
