I have a 98 Regal LS and Every once in a while the radio goes crazy and switches to CD then Gives an E22 Code? This code is not in my manual. I see E20 and a couple of others but not E22. It just happens by it self when I am driving down the road. Seems to be random. Doesn't Happen all the time.

Can anybody tell me what E22 means?:banghead:

Here are common AC Delco fault codes for the CD:

CD Errors
E20 : Focus Error Cause(s): The CD player cannot focus on the disc or there is an internal focus problem. Correction(s): Try cleaning the disc or using a new disc. Make sure the disc is loaded correctly. The road could be too rough or there is too much humidity. If the problem is not corrected, service the unit at an ACDelco® Service Center.
E21 : Tracking Error Cause(s): There is a problem with reading the disc Correction(s): Try cleaning the disc or using a new disc. Make sure the disc is loaded correctly. The road could be too rough or there is too much humidity. If there is still an error, service the unit at an ACDelco® Service Center.
E22: Motor Error Cause(s): The CD motor is not handling the compact disc properly. Correction(s): Service or exchange the unit at an ACDelco® Service Center.
E23 : Communications Error Cause(s): There is a vehicle/radio communication problem or an internal radio communication problem. Correction(s): Disconnect battery voltage to the radio and then reconnect after a few minutes. If there is still an error, send the unit to an ACDelco® Service Center.
