911 Turbo Cabriolet (996) F6-3.6L Turbo (2004)
Function Monitoring
Besides the functions which control the engine operation, the Electronic Control Unit contains extensive monitoring functions which guarantee a fail-safe
vehicle operation in case of a fault.
These functions cover two errors:
-
Error detected in function monitoring (and not in the main function) which causes safety fuel cut-off. Safety fuel cut-off means that the throttle
blade is switched currentless and injection is cut-off long enough so that the engine speed decreases to a permitted non-critical value.
-
Error in torque comparison which le ads to safety fuel cut-off. This error is set when it is recognized that the actual torque of the engine exceeds
the requested torque.
