Idle speed management
This programming is used to calculate the adapted idle speed according to the conditions of use (cold engine, air
conditioning requests, electrical consumer use etc.).
Air supply
This is managed by a motorised throttle valve which is controlled by the injection computer.
The injection computer also performs the following tasks using the motorised throttle:
– management of valve oscillations which can produce undesirable torque,
– management of valve movement subject to mechanical faults when the valve reaches its mechanical boundaries,
– management of acoustic faults by limiting throttle opening at a certain engine speed and when stopping the engine.
Torque management
The torque structure is the system for managing engine torque. It is necessary for some functions such as the
electronic stability program (ESP), automatic transmission (BVA) or sequential gearbox (BVR).
Each computer (ESP, sequential gearbox, automatic transmission) sends a request for torque via the multiplex
network to the injection computer. This arbitrates between the various torque requests and the driver's request
(made via the accelerator pedal or the cruise control/speed limiter).
The result of this arbitration gives the torque setpoint. The computer then calculates the throttle position setpoint, the
ignition advance and the wastegate setpoint (if a turbocharged engine) in order to provide the necessary torque.
Ignition management
Management of ignition advance enables the combustion quality to be managed and therefore engine operation to
be optimised. For a positive advance, the ignition point will be before TDC*, however the advance can have a
negative value.
TDC*: Top Dead Centre.
Fuel supply management
The fuel pump ensures the supply of fuel. It is activated for one second each time the + after ignition feed is switched
on. It ensures the correct level of pressure in the circuit and thereby achieves correct engine starting, particularly if
the vehicle has not been used for a long time. When the engine is running, the pump relay is controlled and
therefore the pump is always active.
The petrol vapour absorber enables petrol vapour to be collected in order to limit its release into the atmosphere.
Richness adjustment
Richness is managed using the upstream and downstream oxygen sensors located on the exhaust. For the sensors
to be operational quickly, they need to be heated by the exhaust gas and by a resistor internal to the sensor. These
sensors reflect the efficiency of combustion and, using information sent to the computer, they enable the quantity of
fuel injected to be managed in order to meet the emission control standards and to ensure optimum engine
operation.

THROTTLE VALVE REPLACEMENT OPERATIONS

– When replacing the inlet throttle valve, switch on the vehicle + after ignition feed, after replacing the part.
– Carry out resetting using command RZ031 Throttle stop programming.
– Switch off the ignition. The inlet valve will run a new programming procedure whilst maintaining the supply (power
latch) due to the reinitialisation phase.
– Check that the programming is correct using status ET051 Throttle stop programming, it must be at 1.
If programming was not performed correctly, repeat the operation from the start.
– If the fault is still present, contact the Techline.
OPERATIONS FOR REPLACING THE BRAKE PEDAL SWITCH
– When replacing the brake pedal switch, switch on the vehicle + after ignition feed, after replacing the part.
– Check that the switch statuses change as follows, when the brake pedal is activated:
–ET039 Brake pedal = 1 and ET799 Brake Wire Contact = 1 when the brake pedal is released
–ET039 Brake pedal = 2 and ET799 Brake Wire Contact = 2 when the brake pedal is depressed
OPERATIONS FOR REPLACING THE TDC (TOP DEAD CENTRE) SENSOR
– Switch on the vehicle + after ignition feed,
– Carry out resetting using command RZ037 Flywheel target programming.
Operation for Programming
– Decelerate a first time with injection cut-off (i.e. feet off the brake, accelerator and clutch pedals) between 3500 and
3000 rpm, in 3rd gear for a BVM* for at least 3 seconds.
– Decelerate a second time with injection cut-off (i.e. feet off the brake, accelerator and clutch pedals) between 2400
and 2000 rpm, in 3rd gear for a BVM* for at least 14 seconds (K4M, K7M engine) or 3 seconds (D4D, F4R, K4M
engine of Duster).
*BVM: Manual gearbox
The programming was successful when status ET089 Flywheel target programming has the value1.

TEST 14
CONTINUEDIgnition coil check
K7M engine
Visually inspect the condition of the connectors of the ignition coil, component code 778 (see MR 388 Mechanical,
17A, Ignition, Coils: Removal - Refitting).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector(s), otherwise replace the wiring.
Insert tool Elé. 1808 (1) in the cap of the wire of the plug concerned.
Fit the assembly in the plug well.
Start the engine and let it idle.
Apply light pressure to the assembly to hold the coil in contact with the tool.
Observe the glow from the electric arc on the spark plug well wall.
If the electric arc is not produced, replace the ignition coil (see MR 388 Mechanical, 17A, Ignition, Coils:
Removal – Refitting).
If the fault is still present, contact the techline.
D4D engine
– Switch on the vehicle + after ignition feed.
– Run command VP036 FUEL SUPPLY INHIBITION.
Put the vehicle under starting conditions:
– position of gear lever in neutral for a manual gearbox* or position "P" (Parking) for an automatic gearbox*.
– brake pedal depressed.
– Run command RZ003 ENGINE ADAPTIVES.
Remove the plugs from each cylinder and check, one after another, that sparks are present by bringing the plug
close to a chassis earth, with the starter engaged. If no spark is produced, replace the ignition coil, component
code 778 (see MR 388 Mechanical, 17A, Ignition, Coils: Removal – Refitting).
If the fault is still present, contact the techline.
