Have a Parking Assist malfunction message with a large yellow triangle when I try to use Parking Assist. Took vehicle to Toyota dealer. They did diagnostic, and I got the following recommendation: Has C1611 for a ECU malfunction. Followed the DIAG chart and would not communicate to set the steering sensor valve due to a faulty camera. Also is having a low voltage issue due to a low battery issue. Needs both a new 12V battery and rear camera assembly. Will need the system re-checked after this. I declined the service because the rear camera is was working perfectly, and I wanted to get the battery checked myself. After checking, battery is also okay. Need a second opinion.
