Radio Error code 2 on a 93 500SEL
Hey all,
A buddy of mine just picked up a 1993 500 SEL with a brand new motor. Lucky him! We are fixing a few little things and this error code came up on the radio. The battery was disconnected and we had to enter the code that I got from dealership. Now the radio doesn't work at all and E 2 keeps flashing....
What gives? Do we need a new radio?
Thanks
EG

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 module, CD changer and trunk mounted tuner/amplifier. If a fault is detected, a DTC E1 thru E5 will appear on the radio display panel.
The code E 2 for the becker audio is as follows:
Possible Cause:
Radio control module, CD changer and tuner/amp will not turn on due to open circuit or poor BUS connection
No voltage
Remedey:
Check BUS cable connections on radio control module and CD changer
Check for continuity between pins on BUS cables
Check condition of fuse on rear of CD changer and tuner/amp
Check for circuits 15, 30 and 31 at the radio control module, CD changer and tuner/amp
Replace tuner/amp
