Highland compensation (pending)
This feature allows the injection quantity to be controlled so that the emission of black smoke due to a low
oxygen concentration is minimized in high-attitude places. By default, the highland compensation feature
(pending) will be disabled.
Engine failure detection
The E-ECU accepts the connection of engine failure detection sensors as shown in Figure 2-51 . Actions to
be taken depending on the status of sensors can be programmed. The sensor status can also be sent via
CAN communication.
A failure lamp can be connected to each sensor. See Figure 2-51 . Be sure to connect a lamp or load
resistance (120
Ω
) to the pressure switch so that the contact current is 100 mA or higher.
