Hello,
I have a 2014 LC that is having some parking sensor issues. I have attempted to disconnect the battery overnight, clear the codes and scan again, checked fuses, physical connections to the sensors, and the parking ECU ("Intuitive P/A") state - all looks good. Techstream continues giving me C1AEC and C1AED codes. When I click the parking assist button I get a warning stating that all sensors are having some issues, or in Toyota language "Check Sonar System". Backup/side/front cameras work fine. Sonar works and is able to keep appropriate distance from the vehicle in front as well.
I have found a similar question here, but it never got resolved:

Does anyone have suggestions on what I else I can check?
Any help is highly appreciated, thank you all.

2013 LC Intuitive P/A Error | TechStream Code C1AED | Repair Manual??
Hello, My rear park assist sensors are going crazy and I'm attempting to get them sorted. TechStream gave a C1AED error under Intuitive P/A, pointing at either a failed parking sensor or the Clearance Warning Computer failed. I'd like to replace the Clearance Warning, or even attempt to remove...

Does anyone have suggestions on what I else I can check?
