I don't have an owners manual for my car. What does error 4 mean on the CD player of a Lexus 2004 rx 330?

Answer 1

I assume you meant he CD player is showing error 4. If this is correct your CD player has an mechanical malfunction. Owners manual may say something about this.

Actually you have two choices. You can go to the dealer and they will tell you (as they told me) that you must replace the entire unit ($750). There are a number of postings offering various solutions including removal of fuse #25 for several minutes then replacing it, and this somewhat longer one:

My CD on my RX is a bog standard but it gives me these errors from time to time, had a few the last month or so when the car is cold, may be the discs are too cold or when the car warms quickly there may be condensation on the disc which will give a read error.

The first few times I had a real problem ejecting the discs until I came upon a simple solution.

Turn the unit off

Then turn off the engine so that no lights are on on the dash

Push down and hold the power button on the CD player, whilst holding it down, turn the key to power up the unit.

Remove your finger from the power button, you may need to press again to switch it on. Error should now clear.

This has never failed to clear the faults I have had ranging from unreadable discs to un-ejectable discs.

I plan on trying this tomorrow - wish me luck
