10. LANE A / LANE B Warning Light Illuminated or Flashing
The Lane warning lights can flash or be permanently
illuminated depending on the nature of the fault.
If a warning indicator remains on permanently, it indicates
that an error with higher severity (Failure) has been detected
by the internal testing procedures of the ECU. In this case,
the ECU will continue to operate in an alternative control
mode, which will transfer the control of ignition and injection
to the error- free Lane.
Regular operation as well as alternative control modes of the
ECU are able to represent the full engine power. The engine
is operated in power-mode with increased fuel consumption.
