b. The connections between the vehicle's various computers are multiplexed.
The electronic system fitted in this vehicle is multiplexed.
It enables dialogue between the various vehicle computers. As a result:
– the fault warning lights on the instrument panel are lit by the multiplex network,
– vehicle faults are displayed by the multiplex network,
– the vehicle speed sensor on the gearbox is not needed.
The vehicle speed signal on the instrument panel is sent by the ABS computer via the multiplex network. The vehicle
speed signal is mainly used by the injection computer, the airbag computer and the automatic transmission
computer (if the vehicle is fitted with this).
c. Functions hosted:
Air conditioning management assistance:
For vehicles with air conditioning, the EDC16C36 system provides the option of deactivating the air conditioning via
the UCH, under certain conditions of use:
– when requested by the driver,
– when starting the engine,
– if the engine overheats (in order to reduce the power the engine has to supply),
– when the engine speed is kept at a very high level (to protect the compressor),
– during transition phases (e.g. under heavy acceleration when overtaking, anti-stalling and moving off strategies).
These conditions are only taken into account when they do not occur repeatedly, in order to prevent system
instabilities (erratic deactivations), when certain faults appear.
Management of the damper valve:
The damper valve currently has three functions:
– the valve closes in order to block the passage of air towards the cylinders to shut off the engine. The aim of this is
to stop the engine as quickly as possible and to reduce instabilities as the engine is switched off.
– “valving” function depending on the engine operation: the damper valve closes by a few % to create a “'venturi”'
effect at the EGR valve passage section.
The aim of this is to accelerate the air flow of EGR gases and to reduce the emission of pollutants.
Thermoplunger management (only on certain F9Q816 engines in VDiag 48):
This vehicle is fitted with thermoplungers. They are managed and activated by the injection system.
There are two types of program:
– controlled by the injection system during particle filter regeneration,
– passenger compartment function; the air conditioning requests the injection to activate one or more thermoplungers
to raise the air temperature in the passenger compartment. The injection computer authorises the actuation or non-
actuation of the thermoplungers according to the operating phases and the power requirements of the engine.
The maximum number of thermoplungers that can be actuated is four. Their actuation depends mainly on the
coolant temperature (< 15°C) and the air temperature (< 5°C).

If all the criteria are met, the computer enters regeneration mode. The injection programming is adjusted in order to
raise the target exhaust gas temperature between 550 and 650°C.
This temperature allows the particles accumulated in the filter to be partially or completely burnt (regenerated).
Regeneration efficiency depends on the particle filter inlet temperature and the time spent in regeneration mode.
Regeneration can be carried out automatically when driving if the weight of soot is less than 70 g and if the number
of regeneration attempts when driving is less than 11 (only for Vdiag 48).
If the weight of soot is greater than 70 g, the user will have to request an After-sales regeneration.
This regeneration is carried out in the workshop. Always follow the instructions written in the interpretation of
commands (SC017 Particle filter regeneration) to perform regeneration in complete safety.
After an After-sales regeneration, always reconfigure certain parameters in the computer using command SC036
Reinitialise programming (see "interpretation of commands").
Warning light management:
Instrument panel display
The computer displays certain information on the instrument panel relating to engine operation. This involves six
functions:
– the pre-postheating warning light,
– the coolant temperature warning message,
– the level 1 fault warning light (non-critical fault),
– the level 2 fault warning light (emergency stop),
– the OBD warning light (European On Board Diagnostic),
– the particle filter specific warning light (F9Q816 engine only).
These six functions are represented by 6 warning lights and/or messages displayed by the on-board computer.
In addition, certain warning lights are, when lit, accompanied by a spoken message on vehicles fitted with a voice
synthesiser (refer to the driver's handbook).
A 3 second visual inspection (automatic test procedure managed by the instrument panel) is carried out by the
injection computer when the ignition is switched on.IMPORTANT
The particle filter must be replaced after a period of time which largely depends on the grade of engine oil used -
this information is in the driver's handbook.
After replacing it, always reconfigure certain parameters in the computer using command SC036 Reinitialise
programming (see "interpretation of commands").
