Fault Recognition In Engine Control Unit

Fault recognition in engine control unit
The following faults are monitored in the engine control unit:

- Interface, i.e. line to EWS control unit: In this case, the check is carried out in order to establish whether a signal is received and whether this signal is not subject to excessive interference.
- Variable code: A check is conducted as to whether the variable code which is sent by the EWS control unit agrees with the value calculated in the DME(DDE) control unit.

Engine start is inhibited if a fault is detected.
