I am able to reproduce an error on my 2005's audio system. Does anyone know what "Error 4" means? I have to actually turn off the car to reset the CD player.

Here's how I reproduce it:

Background:

• It's a non-ML system
• 6-CD changer, cassette, AM/FM
• I have six CD's loaded into the system

Steps:

1. When listening to FM radio, push the CD button
2. Press the "Disk" up-arrow button rapidly (it is the radio station preset #4 button) to change disks. I usually cycle through five or six rapid disk changes, normally going from Disk 1 to Disk 6, in a fast manner.

Sure enough, after the fourth or fifth (maybe sixth) button press, "Error 4" flashes on the display. At this point, I can't do anything with the CD player. I can, however, switch to radio and listen as usual.

To reset the error message and to begin using the CD player again, I have to turn off the ignition. Turning off just the audio system doesn't reset the error.

It's annoying. I'm still under warranty, so should I take it in to be "fixed"?

does this happen when you scroll slowly?

 

My guess is that Error 4 means "stop doing that."

 

There you go, error 4 means, ho-ho-ho slow down....why are you in hurry anyway? But it does not hurt to show and tell when you come in to the dealer....the Manual will say: Advise the Owner to lessen caffeine intake.....

 

I've had that before, too!
I don't think I ever got it from scrolling through CD's too quickly, though.
It takes a while to go away.

 

Yes, it still produces the error.

I think I narrowed the problem down to a particular CD. While "turbo-scrolling", the error usually appears when switching to Disc #6. When I removed that CD, I could scroll as fast as I wanted through discs 1 through 5. When I put the CD back into slot 6, the error returned.

The uniqueness of this CD is that I had burned it myself. The other discs 1-5 are a combination of commercially burned CDs and CDs that were burned by my daughter.

Later, I'll reburn the CD and see what happens.

There you go....the power od deductive reasoning. Did you try using all OEM CD's? Bet you Error 4 is disc can not read...

 

hummm better get some technical advise from your daughter before you burn another cd.

 

leuxs systems tend not to like rewritable discs. They still work, but its a bit edgy

 

Try using cd-r, not cd-rw.

 

Exactly what I was thinking! LOL!

I'm not sure which discs I used. I'll check it out on the way home from work later.

Okay, the disc is a CD-R after all. However, once I took it out and reloaded it, I am unable to reproduce the error. No matter how fast I scroll through the CDs, it works!

Hmm...oh well, who knows what it could have been--at least things are working now.

Thank for all the suggestions!

According to my files, "Error 4" is a mechanical disc loading problem. The disc probably hasn't been seating in the #6 carrier properly, leading to some mechanical interference when it is selected. It would seem to be properly seated now, but next time you have it out you might check it on a perfectly smooth flat surface to be sure it is not warped slightly. Try another disc in that position, one you know to be trouble-free.

I burn a lot of discs for my clients and have never had a problem with the mid or high-grade discs from Taiyo Yuden, and others. Even lesser discs like Ritek perform fairly well. Some brands - usually the no-names - fail right out of the box. One of the problems seems to be that the cheapest discs are pretty thin and subject to mechanical problems like warping.

If you use "economy" discs particularly, be sure to put a label on them. Most of the cheap discs don't have much of a protective coat on top and scratching the top metal foil finish can lead to serious playback troubles as the disc is read by the laser from the bottom.. In addition to telling you what's ON the disc, the label helps protect that critical foil.

 

That's great information, Lil4X.

Thanks for the research into the error code (and for the "heads-up" on the various CD brands).
