DTC B1214 Short to B+ in Door System Communication Bus Malfunction
DTC B1215 Short to GND in Door System Communication Bus Malfunction
DESCRIPTION
DTCs B1214 and B1215 are output when a short to +B or the body ground occurs on the communication bus. Detecting this condition disables all the BEAN communication and outputs some DTCs.
