BMW Fault Codes
(DTCs)
Below is a comprehensive listing of

looks for feedback through
shunt resistor in harness to
determine if ignition actually
occurred.

DME final stage will set flag
whenever a short to ground, a
short to battery voltage or a
disconnection between output
transistor and component
exists.
