Question about Car Audio & Video

2 Answers

I own a Lexus RX 330 with a six disk CD player and I am having trouble loading CD's. After several attempt to load a disk it opens the door and allows one to load, but then produces error message 4. I have found it helpful to turn the cars ignition on and off during the process of trying to load the CD. Once it is loaded and does start to play, all is fine. I'm from the old school and feel like spying a can of WD-40 in it but have been advise by my 12 year old grandson that may not be such a good idea. And what's up with the Passenger air bag message on the dash board displaying passengers air bag off, even with a passenger (wife) in the seat with seat belt on asking, what does that mean? The message does go away after I start the car, but the questioner remains. Other then that I do enjoy this car. Any help would be helpful.

Hi! Please try this to resolve the problem. Open the hood and remove the positive battery connector and let it sit for atleast 5mins. then reconnect it again to reset the system and may resolve the problem. Hope this helps and thank you for using FixYa!

    It will reset everything once you disconnect the positive battery connector.



Open the fuse box under the hood and locate fuse #25, the audio fuse. Pull it out for ten minutes and this will reset your CD player and clear the error 4 message. If it still does not work then replace the fuse. A dirty or scratched CD will cause this error code to come up. The airbag light problem has a technical service bullentin from Lexus and you will need to take it in to have them fix that free of charge. Here is the TSB:
Lexus RX330 Technical Service Bulletins (Recent) Body, Interior & Misc.: AIR BAGS Service Bulletin Number: EL001-08 NHTSA Number: 10024642 Model Years Affected: 2007 Date of Bulletin: 05/2008 Bulletin Summary: REPAIR MANUAL SUPPLEMENT: SRS LIGHT [ON} - DTC B0111/B0116 - OPEN SIDE SQUIB CIRCUIT.

2004 lexus RX330. CD player has 6 cd's in it. Has one cd in it. Will not play or eject. Error 4

Something inside the cd player has broken and can most likely be sent off for repair but I don't know how much that would cost, but a new one can range anywhere from $500-$1,000.

As the consumer there is nothing U can do to fix this problem, the error code is for a radio technician with the right technical publications and tools to fix the problem, you will have to pull the radio/CD player and send it out for repair with an authorized Lexus sound system repair station.

Error 04 CD player's easy to fix. Open the fuse box under the hood. Find the audio fuse. Pull it out for 10-15 minutes to reset the cdplayer. Plug it back in and problem solved. If it still does not work just change the fuse. I had that problem and had to search high and low for a solution and found it
on some web site. IT WORKED...will save you $800 that Lexus charges to do the same thing.
