Fault finding – Function13B
MANAGEMENT OF PRE/POSTHEATING
Pre-postheating management involves controlling the heater plugs and the heater plugs indicator light on the
instrument panel (via the multiplex network). The heater plugs are activated by a preheating unit and the power is
provided by the battery.
When the ignition is switched on, the preheating period is activated; the indicator light comes on for a period
dependent on the battery voltage, atmospheric pressure and coolant temperature.
When the coolant temperature is below a certain threshold, a postheating function enables combustion stability,
and thereby engine operation, to be improved (reduction in unburned fuel and pollutant emissions).
MANAGEMENT OF ENGINE COOLANT TEMPERATURE
Engine cooling is guaranteed by a 2-speed fan assembly (GMV) (slow: GMV1 and fast: GMV2).
The injection computer requests the UPC to actuate them via the multiplex network.
To provide cooling:
– Engine running:
GMV1 is activated when the coolant temperature exceeds 96°C and is deactivated when it drops below 94°C.
GMV2 is activated when the coolant temperature exceeds 104°C and is deactivated when it drops below 102°C.
If the engine coolant temperature exceeds the warning threshold of 120°C, the injection computer requests the
instrument panel computer, via the multiplex network, to switch on the coolant temperature warning light. The
warning stops if the coolant temperature drops below 117 ° C.
If the engine coolant temperature exceeds the threshold of 11 5 ° C, the injection computer requests the UPC
computer, via the multiplex network, to switch off the air conditioning compressor so as to reduce the load on the
engine and attempt to limit its rise in temperature. The cut-off request is cancelled if the coolant temperature drops
below 110°C.
If a fault in the coolant temperature sensor circuit is detected, the injection computer requests that the coolant
temperature warning light is lit and that GMV2 is activated.
In addition to engine management, the injection computer centralises the cooling requirements for the air
conditioning and automatic gearbox/sequential gearbox functions (if fitted to the vehicle).
OTHER HOSTED FUNCTIONS
The other functions hosted by the computer are:
– Multiplex line.
– ADAC (Trip Computer).
– Trip Computer Display.
– Engine immobiliser.
– Airbag.
– Engine stop management.
– Starter management.
– Air conditioning.
– Cruise control/speed limiter.

INTERSYSTEM EXCHANGES
The inter-system connections concerning the particular requirements of engine management are as follows:
●Request for injection computer to switch on the OBD warning light to warn of an OBD related pollution fault.
●Request to switch on the Level 1 warning light to warn of an operational safety fault with the engine
management system which may restrict performance.
●Request to switch on the Level 2 warning light to warn of an operational safety fault with the engine
management system which may result in the engine stopping.
●Request to switch on the Particle Filter and Service warning light to warn of an operational safety fault of the
particle filter system which may result in reduced performance or engine stoppage.
●Request to switch on the Engine overheating warning light to warn of an engine overheating fault or a fault
in the coolant temperature sensor.
●Request to switch on the Particle filter warning light to warn the driver that the particle filter is loaded with
particles (weight of soot more than 30.8 g). As soon as possible, the driver must drive at a speed of more than
25 mph (40 km/h) for 2 minutes to activate regeneration.
The driver must maintain a speed of more than 25 mph (40 km/h) until the particle filter warning light goes out
(Vdiag 45 and 49 only).
●Request to start the fan assembly for engine cooling and also for air conditioning purposes,
●Request to switch off the air conditioning compressor for engine programming requirements such as pulling
away, performance, anti-stalling, overspeed, etc.
●Request to switch off electrical consumers (passenger compartment heating resistor (if fitted), heated rear
screen, etc.) for engine operation purposes such as: pulling away, performance, anti-stalling,
overspeed, etc.
●Formulation of requests to engage electrical consumers and limit power as a function of rail conditions.
This last function is made possible with the introduction of alternator control. Formulation of requests enables
the smooth running of the engine to be improved in the critical operating phases, mainly at idle speed and
when pulling away. These requests pass via the multiplex network to the Protection and Switching Unit where
they are converted before being sent to the alternator.
In comparison to the version without a particle filter (K9K Step 2), the K9K Step 2 particle filter technical
specifications also include:
●Four temperature sensors spread along the exhaust system.
●One differential pressure sensor.
●One fuel injector with a dedicated electric fuel pump.
●An electric water pump (in addition to the mechanical pump) controlled by a relay to cool the turbocharger when
the engine is stopped (only for Clio III, Modus and Mégane II/Scénic II).
●Four heating elements and their control unit.
Oil Control System (OCS) (except Vdiag 44, 45 and 49)
This program takes into account the driving style of the user to warn him of the need for an oil change. This program
counts the number of miles since the last oil change, corrected by a factor which depends on the oil temperature.
When the number of miles exceeds a threshold, the customer is warned by a message to the instrument panel that
the drain must be performed.
After the oil change, the user must reset the oil change interval on the instrument panel.
