I had an audio shop install a subwoofer and amplifier today and the car is showing a RCTA error with a rear camera error. Any assistance to clear this would be great.

Could it be by them disconnecting the battery it caused this?

 

Did they unplug any wires? possibly could have been an unplugged wire or even a blown fuse?

 

They claimed that they did not,

 

Try resetting this?

 

I tried that and it still didn’t work

 

I also have the RCD error simultaneously

 

After trying the steering angle reset etc it’s still not working, when I shift into reverse I do have the grid lines etc, and do have reverse camera operation. I’m thinking when they disconnected the battery perhaps there maybe an electrical glitch. I did use a Launch Creader v2.0 as a diagnostic tool to attempt to clear the error but nothing productive. I am 1 step from taking it to the local dealer for assistance

 

Glitch? They cut a wire. Handing the car to you with the error tells you they are clueless.

 

I have an appointment at the dealership tomorrow morning. They claimed to have double checked everything. I should have some answers after that

 

This is a Lexus dealership you are working with?

 

I’m taking it to a Lexus dealer tomorrow

 

After taking the car to the dealer they determined that the car needed an entire floor harness at $6500 for the part and $6900 to install as there was evidence of what appeared to be a rodent chewing on it

 

That rat must've been a German car enthusiast. At least it didn't die somewhere difficult to track. Happened to my son with his Camry.
