The ISG system is strongly networked with the power management.
In the event of battery replacement, disconnection of the battery terminal
or after changing the engine management system, the reference data regarding
the battery charge state and battery condition can be lost.
They are only available again a closed-circuit current measurement
of approximate 4 hours in which the vehicle may not be wakened. In this
time, the ISG system is inactive.

Fault in communication line (LIN/CAN)
Fault Electric oil pump
Fault ESC System
Fault Limp home mode

Fault brake booster vacuum pressure sensor
Fault Brake master cylinder pressure sensor
Fault Brake pedal switch

When the ISG related sensors or system error occurs, the ISG OFF
switch lights up. Especially when the battery sensor is replaced or
reinstalled, the vehicle must be placed in the ignition switch OFF for
about 4 hours for recalibration.
The ISG function is operated about 4 hours later normally. But
in the case of first 25 times, the ISG function can be operated regardless
of recalibration.
|
|
When the engine is in Idle stop mode, it's possible to restart
the engine without the driver taking any action.
Before leaving the car or doing anything in the engine room area,
stop the engine by turning the ignition key to the LOCK position or
removing it.
