BECKER TWO - PIECE RADIO ERROR CODES
The Becker two - piece radio has a self-diagnostic system. The system verifies data exchange via the BUS cable between the dash mounted Radio control
unit (A2/4), CD changer (A2/6) and trunk mounted Tuner/amplifier (A2/3). If a fault is detected, an error code, E1 through E5, will appear in the radio
display. There is no procedure required to access radio error codes.
The Diagnostic chart below cross references error code - possible cause - remedy.
Note:
If more than one remedy is listed, they are to be performed in the sequence listed.
