Audio System - Erroneous Radio trouble Code

NUMBER: 08-021-04

GROUP: Electrical

DATE: May 25, 2004

SUBJECT:
Erroneous Radio Diagnostic Trouble Code (DTC)

MODELS:

2005 (LX) 300/Magnum

DISCUSSION:

Navigation radios (Sale Code REC, p/n 56038646AJ, or Sales Code REJ, p/n 05091508AE) may log internal DTC B221E (Radio Internal Mechanical Failure) when the ignition is turned on, even though the CD/DVD mechanism is working properly and the vehicle operator has not experienced a CD/DVD malfunction.

The internal DTC B221E will be displayed as a "Stored" DTC. Sometimes, multiple B221E DTC's are displayed. They should all be in "Stored" status.

Do not replace REG or REJ navigation radios based solely on the radio internal DTC B221E. In most cases, this is an erroneous DTC with REG AJ level parts and REJ AE level parts. Ignore all internal B221 E DTC's in an LX vehicle and do not replace REG or REJ radios, unless a CD/DVD mechanical failure is confirmed.
