Radio and Tire pressure related?

Hi, I own a 2007 Toyota Corolla LE. I bought the car with a six cd changer in it, and now it doesn’t seem to work. Whenever I put a CD in it (mind you, these are purchased CD’s), it will either give me and error3 message or it will play the first track of the CD before it goes silent and ultimately shows an error1 message. I have tried using older and newer CD’s as well as having the car battery unplugged. This isn’t a urgent problem, but around the same time, the tire pressure warning light started to come on and will not turn off despite me checking tire pressure and resetting it several time. I’m concerned these are related.



Any advice?

Google is your friend. Try this link. It looks like the plastic tray is toast and that means the fix is a new radio, but read the link, I only skimmed it.

How many miles do you have on your odometer? If your car’s bumper-to-bumper warranty is still in effect, simply take it to the dealership for free repair.

If you are not sure about the duration of the bumper-to-bumper warranty, check your Owner’s Manual or other materials in the glove compartment for details.

Also–bear in mind that you are not required to provide a diagnosis to the dealership, and, in fact, they will undoubtedly ignore any diagnosis that you provide. The dealership is required to go through a standardized diagnostic protocol in order to avoid “throwing parts at the problem”, and following a diagnostic protocol is less likely to result in errors, as compared to following random suggestions.

I agree. This sounds like a warranty issue to me. Let the dealer replace the radio and figure out what’s going on with the tire pressure monitor system. Don’t guess.

Your tire pressure system (TPMS) might be reading a low spare tire. Don’t forget to check the pressure in your spare.
