Fiat TIPO 2015 Mode D'emploi page 130

The BCM manages the Logistic mode function. Some electrical loads are deactivated when the
function is active.
The Logistic mode can be deactivated using the diagnosis equipment (the command is in the
"miscellaneous functions" menu of the BCM).
The configuration of the vehicle on those with Next-Generation architecture is called PROXY. PROXY
consists of a computer file with a maximum of 255 bytes. All modules requiring configuration will store
a specific version of the PROXY file. All other modules store only the part of the file pertaining to that
module.
The BCM uses the PROXY file to perform a vehicle configuration check when the ignition key is turned
to the ON position. The BCM sends a PROXY configuration code to PROXY configured modules on all
the networks. PROXY configured modules will reply with their own configuration code. The BCM then
compares the codes. If a code mismatch is detected, the BCM will set a diagnostic trouble code
(DTC). If the DTC is present for three ignition cycles, the BCM sends a message to the IPC to flash
the odometer.
The following diagnosis functions are in the "Miscellaneous Functions" menu of the BCM:
1. Restore Proxy configuration
2. Proxy alignment
Restoring the Proxy configuration allows you to rewrite, via wiTECH connected to the web, the proxy
in the BCM.
Proxy alignment allows the BCM to send the appropriate part of the Proxy to each individual module.
For example:
If the ORC (airbag) module is replaced during servicing, it needs to receive the airbag Proxy
information from the BCM in order to configure itself.
The BCM extracts the part relating to the airbag module from the Proxy and sends it to the latter in a
file.
The Proxy alignment must always be carried out after running "restore vehicle configuration".
