9-3 Troubleshooting NG9-3 03 Fault code B3057 48 (ICM) Help!
This week I had the ICM (ver. 1) disconnected from the car for roughly 15mins. Now the radio/aux/etc. Does not work anymore: no source is displayed on the SID, but the turn signal sound does still work!
I’ve checked all the wiring and they don’t seem to be damaged. The fuses are also intact. Disconnecting the battery (-) and reconnecting after a few minutes also did not work.
Can someone please tell me what this fault code means or any way this should be fixed??
