BMW fault code 0001
Radio-control system
FBZV: fault saved
Module version: Radio-control system (FBZV)
In: 7 Series (E38) 1994–1998
Reading and clearing it
Fault code 0001 is a BMW code, stored in the car's radio-control system, not a generic OBD2 code (P0xxx): a generic OBD2 reader only reaches the engine's emissions faults, so it won't show it. AutoLingo for BMW reads it with BMW's own diagnostic protocols, in plain English, with the details the module stored about it, and clears it after a repair. If a fault comes right back after it's cleared, the problem is still there.
The radio-control system is on: 8 Series (E31), 5 Series (E34), 7 Series (E38)
