DTC B0022 CD Player Error

Conditions for Setting the DTC

With the ignition in either the Accessories position or the On position, DTC B0022 will set to indicate that an error message has been received from the CD Changer due to a disc playing error. This error is due to problems in reading the CD, and it may be set due to the following actions:

    • CD was loaded upside down.
    • CD mechanism was unable to play it.
    • Computer Data CD was loaded.
    • CD mechanism was unable to play it.
    • Disc was badly damaged and could not be read.
    • Disc was blank.
    • Conditions were too severe for the CD Changer to read the CD. For example, too much vibration.

The DTC will remain set even though a faulty CD might have been removed already or the fault was cleared.
