5. FAULT FINDING LOG
You will always be asked for this log:
– when requesting technical assistance from Techline,
– for approval requests when replacing parts for which approval is mandatory,
– to be attached to monitored parts for which reimbursement is requested. The log is needed for warranty
reimbursement, and enables better analysis of the parts removed.
6. SAFETY INSTRUCTIONS
The safety instructions must be followed at all times when working on components, to avoid damage or injury:
– check the battery voltage to avoid incorrect operation of computer functions,
– use the proper tools.IMPORTANT!IMPORTANT
Any fault on a complex system requires thorough fault finding with the appropriate tools. The
FAULT FINDING LOG, which should be completed during the fault finding procedure, ensures a
record is kept of the procedure carried out. It is an essential document when consulting the
manufacturer.
IT IS THEREFORE ESSENTIAL THAT THE FAULT FINDING LOG IS FILLED OUT EVERY TIME IT IS
REQUESTED BY TECHLINE OR THE WARRANTY RETURNS DEPARTMENT

Fault finding – Function13B
AIR SUPPLY
Measurement of the fresh air flow
The flow of fresh air entering the engine is measured by a flow sensor (ratiometric hot-wire sensor).
A fresh air temperature sensor is integrated into the air flowmeter.
EGR valve control
The EGR (exhaust gas recirculation) system consists of a direct current EGR valve fitted with a valve position
sensor. The EGR valve is controlled in a closed-loop via the position sensor. Up to a certain rate, exhaust gas
recirculation enables nitrogen oxide (NOx) emissions to be reduced significantly.
Turbocharger control
The turbocharger system consists of a solenoid valve connected to the vacuum pump circuit, which controls the
vanes via a diaphragm to create an overpressure or a vacuum in the fresh air inlet circuit (the overpressure can
reach 2.6 bar).
Damper valve control (for Vdiag 44, 45, 48, 49 and 4D only)
By default the valve is open when in the rest position and is actuated only when the engine is switched off; this has
a damping effect and helps to stop the engine.
It also controls the flow of fresh air during regeneration.
IDLE SPEED MANAGEMENT
The injection computer regulates the idle speed according to the idle speed setpoint which it calculates.
The idle speed setpoint is dependent on:
– the coolant temperature,
– the emission control programs,
– air conditioning requirements,
– the gear ratio engaged (automatic or sequential gearbox),
– the electrical consumers,
– battery voltage.
ENGINE TORQUE MANAGEMENT
The torque structure is the system which translates the driver's request into a torque supplied by the engine. Certain
functions such as the electronic stability program (ESP), the automatic gearbox (BVA) or the sequential gearbox
(BVR), if fitted to the vehicle, use this information.
Each inter-system (ESP, automatic gearbox, sequential gearbox) sends the injection computer a torque request via
the multiplex network.
The injection computer arbitrates between the inter-system torque requests and the driver request (depressing the
accelerator pedal or setting the cruise control/speed limiter function). The result of the arbitration gives the torque
setpoint.
From this torque set point, the computer determines the quantity of fuel to be injected (injection duration and number
of injection processes) and the amount of air required (turbocharging pressure and EGR valve rate) so that the
engine is able to provide the torque required in the best possible conditions (in terms of smooth running
performance, pollutant emissions, etc.).

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.

COMPUTER REPROGRAMMING OPERATIONS
The system can be reprogrammed via the diagnostic socket using the RENAULT CLIP diagnostic tool (see
Technical Note 3585A, Computer programming and reprogramming procedure).
Note:
Before reprogramming the injection computer, move the main Cruise control - Speed limiter switch to the rest
position. The information about the cruise control or the speed limiter displayed on the instrument panel disappears.
Otherwise, if the main switch remains in the cruise control or speed limiter position during and after reprogramming,
the Cruise control/Speed limiter function will not be operational. The procedure for resetting the function is as
follows:
– Vehicle ignition on.
– Main switch in rest position (the computer then detects the rest position).
– Switch in Cruise control position to activate the Cruise control function.
– Switch in Speed limiter position to activate the Speed limiter function.
While the computer is being reprogrammed the fan assemblies are triggered automatically.
Before reprogramming the computer:
– Save the computer data to the diagnostic tool (engine adaptives) by performing command SC003 Save
computer data.
After any computer reprogramming operation:
– Switch the ignition off and then on again,
–Use the diagnostic tool to carry out the following procedures:
– run command RZ019 Programming reinitialisation.
– run command SC001 Write saved data to restore the engine adaptives,
– run command SC013 Enter VIN,
– start the engine (warning: the start-up phase may last up to 30 seconds),
– after injection computer reprogramming, stored faults may appear in other computers. Clear the fault memory of
these computers,
– carry out a road test followed by another check with the diagnostic tool.
DO NOT CARRY OUT ANY INJECTOR CODE WRITING ON THE SIEMENS SID304 AND 301 INJECTION
SYSTEMS.IMPORTANT
Switch on the diagnostic tool (mains or cigarette lighter supply).
Connect a battery charger.
Switch off all the electrical consumers (lights, interior lighting, air conditioning, radio CD, etc.).
Wait for the engine to cool (engine coolant temperature < 60 °C and air temperature < 50 °C).
