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).

Fault finding – Interpretation of statuses13B
ET415CRUISE CONTROL/SPEED LIMITER DEACTIVATION
STATUS DEFINITIONThis status varies according to engine specifications.
NOTESSpecial notes:
Apply the conformity check to see if the statuses are inconsistent with the operating
programs of the system.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
> 80°C
STATUS 1Traction control request.
STATUS 2Brake pedal depressed.
STATUS 3Clutch pedal depressed.
STATUS 4Suspend button pressed.
STATUS 5Cruise control or speed limiter monitoring.
STATUS 6Inconsistency between the request and the vehicle speed. Gear lever in neutral
(manual gearbox) or the neutral position (automatic gearbox).

ET415
CONTINUED 3
STATUS 3
Clutch pedal depressed
Manual gearbox ONLY
The cruise control function is deactivated when the gearbox is no longer coupled to
the engine (clutch pedal depressed).
Status ET415 becomes STATUS 3 when driving with cruise control active
(ET042 Cruise control/speed limiter: CRUISE CONTROL) and the clutch pedal is
depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
If status ET415 becomes STATUS 3 without the clutch pedal being depressed,
consult the interpretation of status ET405 Clutch pedal switch.
If the vehicle is fitted with an automatic transmission:
Test the multiplex network: check the configuration of the multiplex network in relation
to the vehicle's technical specification, especially the configuration of the automatic
transmission computer (see 88B, Multiplexing).
STATUS 4Cancel button pressed
The cruise control/speed limiter function is deactivated whenever the suspend button
is pressed.
Status ET415 becomes STATUS 4, when driving when:
– Either the cruise control is active, or
– the speed limiter is active
– and when the "0" button is pressed by the driver.
This action deactivates the Cruise control/Speed limiter.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
If status ET415 becomes STATUS 4 without pressing the 0 button, consult the
interpretation of status ET703 Cruise control/speed limiter buttons and run fault-
finding on the R/0 control button located on the steering wheel, to the right.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

STATUS 5
Cruise control or speed limiter monitoring
This status appears when the vehicle brakes or decelerates sharply without the
injection computer receiving a signal that the brake pedal switch has been pressed.
If status ET415 is STATUS 5, consult the interpretation of statuses:
– ET042 Cruise control/speed limiter
– ET703 Cruise control/speed limiter buttons
– ET704 Brake switch No. 1
– ET705 Brake switch No. 2
to test the cruise control/speed limiter system components and find the defective
component.
Also, check the operation of the accelerator pedal, and use the diagnostic tool to
check the presence of a fault connected with this component. Deal with them if
necessary.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
If status ET415 changes to STATUS 5, deal with faults present or stored in the
injection computer.
If the fault is still present, contact the Techline.
STATUS 6Gear lever in neutral (manual gearbox) or the neutral position (automatic
gearbox)
Status ET415 becomes STATUS 6, when driving with cruise control active
(ET042: Cruise control/speed limiter: CRUISE CONTROL) and:
– if the driver puts the gear lever in neutral position on a manual gearbox without
declutching or,
– if the gear lever is put in neutral on an automatic transmission.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
If status ET415 becomes STATUS 6 without shifting the gear lever into neutral on a
manual gearbox without declutching, or into the neutral position on an automatic
transmission, test the ABS computer and check the configuration of the tyre size
stored in the computer.
If the configuration is correct, contact the Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

Fault finding – Interpretation of commands13B
VP036INHIBIT FUEL SUPPLY
NOTESThis command enables you to disable the supply to the injectors.
This command is carried out with the engine switched off, and ignition on.
This command allows the injectors to be locked, so that starting is not possible.
Command VP036 allows the engine compressions to be checked in complete safety without disconnecting the
injector connectors or the TDC sensor.
Procedure to follow: (cylinder no. 1 is located on the flywheel end).
– Remove all the heater plugs, connect the compression gauge.
– Position the gear lever in neutral (manual gearbox) or on position P (automatic gearbox).
– Depress the brake pedal and maintain this position.
– Activate command VP036.
– Try to start the vehicle.
– Check the engine compressions.
Start the procedure again on another cylinder.
WARNING
Keep the brake pedal depressed for the length of the test.
Re-establish control of the injectors using command VP037 Stop fuel supply inhibition.

Apply Technical Note 5164A, Noise fault finding procedure.
Note:
Pay close attention to faulty components that might result in unjustified replacement of the turbocharger. For
example, whistling does not necessarily indicate damage to the turbocharger (this could be coming from the
exhaust, the timing, the gearbox, etc.).
