FIAT TIPO -55- REV 0.0
Conditions managed by the BCM
Battery not sufficiently charged or flat:
The BCM receives information from the IBS on the status of the battery charge.
If the IBS is being recalibrated, the engine cut-out is not allowed if one of the following conditions
occurs:
the battery Function Status (SOF) is below 8.3 V
the battery temperature is below −23°C
If the IBS is not being recalibrated, the engine cut-out is not allowed if one of the following conditions
occurs:
the battery Charge Status (SOC) is below 75%
the battery Health Status (SOH) is below 60%
the battery Function Status (SOF) is below 8.2 V
the battery temperature is below −23°C
IBS failure: the automatic engine cut-out is not allowed if an IBS malfunction occurs.
Voltage Stabiliser failure: the automatic engine cut-out is not allowed if Voltage Stabiliser
malfunction occurs.
Driver's door not closed: the automatic engine cut-out is not allowed if the driver's door is open.
Driver's seat belt unfastened: the engine automatic cut-out is not allowed if the driver's seat belt is
unfastened.
Outside temperature sensor: when the outside temperature sensor is fitted, the automatic engine
cut-out is not allowed if:
the outside temperature is lower than the limit Temp_min_1 (−14°C)
the outside temperature is higher than the limit Temp_max_1 (80°C)
NOTE. The temperature limits that have been set on the outside temperature sensor are "extreme"
and therefore must always be respected.
Automatic climate control: the automatic engine cut-out is not allowed if the difference between
the climate control temperature set by the customer and the temperature inside the passenger
compartment is greater than ± 4°C.
NOTE. in the case of manual air conditioning, the engine can always be stopped.
Alternator fault: the automatic engine cut-out is not allowed in the case of alternator malfunction.
Engine bonnet open: if the bonnet switch is fitted, the automatic engine cut-out is not allowed if the
bonnet is open.
Logistic Mode status active: the automatic engine cut-out is not allowed if the Logistic Mode status
is active.
SPM semi-automatic parking system: when the semi-automatic parking system is fitted, the
automatic engine cut-out is not allowed if the system is active.
Failure on BCM relay: the automatic engine cut-out is not allowed in the case of malfunction of the
start-up circuit relay operated by the BCM.
