Emergency operation mode of the control unit (Nissan Serena C24)

When the emergency mode of the control unit is activated as a result of damage to the main sensors, control is carried out according to a pre-set program, while the engine (automobile) goes into safe mode and remains functional.

Status and indication

Note:

In case of simultaneous failure of the throttle sensor and the air mass sensor, the idle position is determined using the throttle switch (contact No.43 of the control unit: throttle switch signal).

In addition, depending on the state of the switch (ON or OFF.) the width of the fuel injection pulses changes. You can continue driving. However, at a speed of about 2400/min, the fuel supply is interrupted.
