Cranking - Fiat TIPO 2015 Mode D'emploi

Engine automatically switched off conditions
When the engine has been automatically switched off for the Stop/Start function, a request can be
generated by a device/control unit, which requires the automatic restarting of the engine.
The BCM collects the information coming from the vehicle and, if necessary, requires the ECM to
automatically restart the engine (the ECM checks first whether safe automatic restarting conditions
are satisfied).
The decision to request or not request an automatic stop by the BCM is translated into a signal
produced by the BCM and sent, through the C-CAN, to the ECM.
The following flowchart describes the strategy used by the BCM to manage the information from the
IBS and the procedure for asking/not asking for an automatic stop.

Cranking

Key start-up is controlled by the user by placing the key in the starting position: under these
circumstances starting is managed by BCM, and by ECM.
Inside the BCM is a relay, R2, the power line of which is in series with the power line of relay R1
managed by the ECM.
