The core of the EMS is the engine control unit (ECU), which consists of
two modules. These modules will be denoted by LANE A and LANE B,
each one capable of taking over control, regulation and monitoring of the
engine. In error-free engine operation, both LANES are turned ON.
During engine control by LANE A, LANE B ensures that the engine ope-
ration can be maintained even after a failure or reduced functionality of
LANE A. Depending on the activity and the failure status of the two
LANES, the ECU automatically selects a LANE to take over control of the
engine.
