VI - Pre-postheating actuation
Pre/postheating control involves actuating the heater plugs and the preheating indicator light on the instrument
panel (multiplex signal).
The heater plugs are actuated by a static relay.
After the ignition is switched on, a preheating delay is activated. The length of time that the warning light is lit
depends on the coolant temperature, air temperature, atmospheric pressure and battery voltage. When the coolant
temperature is below a certain threshold, a postheating function can be used to improve the combustion stability,
and consequently engine operation (reducing unburnt particles and pollutant emissions). Postheating can last up
to5 minutes.
IMPORTANT:
There are two types of heater plug: SLOW and FAST:
SLOW plugs are identified by a black ring.
FAST plugs are identified by a white ring.
The heater plugs fitted on the vehicle must be replaced with plugs of the same type; otherwise there is
a risk of the heater plugs deteriorating which could lead to engine destruction.
Only Vdiag 20, 24, 38 and 74:
when replacing heater plugs with plugs which differ from those currently fitted on the vehicle (replacement of
SLOW plugs with FAST plugs), the computer must be configured (see Replacement of components, Replacing
heater plugs) by running command SC036 Reinitialise programming and selecting Heater plugs if this choice
is available, then following the procedure.

COMPUTER REPLACEMENT OR REPROGRAMMING
Two operations must be performed when replacing or reprogramming the computer:
SC003 Save computer data and SC001 Enter saved data.
–Run SC003 before replacing or reprogramming the computer. This enables certain data to be saved in the
diagnostic tool so that the new computer* can be reconfigured like the old one. The saved data includes: injector
codes, EGR programming, specific data for particle filter operation and vehicle options.
–Run SC001 after replacing or reprogramming the computer. It enables you to rewrite the data (saved by
command SC003) to the new computer*.
Only Vdiag 20, 24, 38 and 74:
–Run SC036 Reinitialise programming and select Heater plugs (see Interpretation of commands); this will allow
you to configure the correct type of heater plugs fitted on the vehicle, if necessary.
If you cannot establish dialogue with the computer being replaced: you will not be able to save anything. After
replacing the computer:
– Write the IMA codes for each injector manually by reading the code on each injector; run command SC002 Enter
injector codes.
– Check the exhaust pipe for leaks or blockage. Repair if necessary.
– Perform an After-Sales regeneration, follow the procedure for command SC017 Particle filter regeneration (see
Interpretation of commands).
– It is essential to change the engine oil and oil filter.
– Enter the data specific to particle filter operation by running SC036 Reinitialise programming and selecting after
replacing injection computer with no save option.
– Enter the VIN into the computer, use command VP010 Enter VIN.
–Only for Vdiag 20, 24, 38 and 74: Configure the type of heater plugs fitted on the vehicle by running SC036
Reinitialise programming and selecting Heater plugs (see Interpretation of commands).
Exhaust gas recirculation valve data is programmed automatically the 1st time the new computer is turned on*.
* New computer or reprogrammed computer.
IMA*: Individual injector correctionOperations to be carried out before the injection computer is reprogrammed:
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.
• Position the cruise control/speed limiter switch in the rest position (the computer detects the rest position at that
moment).
• Position the cruise control/speed limiter switch in the Cruise control position to activate the cruise control
function.
• Position the cruise control/speed limiter switch in the Speed limiter position to activate the speed limiter function.

REPLACING THE EXHAUST GAS RECIRCULATION (EGR) VALVE
After the exhaust gas recirculation valve has been replaced, the computer must store the new valve offset, and the
offset measured when the ignition was last switched off (in power latch phase), which corresponds to the valve
closing.
Using this data, the computer can detect whether the valve is clogged or seized.
When the valve is replaced, clear the stored offsets so that the program uses the new valve’s offset value.
The data associated with this program is compiled in the Emission control / EOBD (European On Board
Diagnostic) sub-function.
–PR128: FIRST EGR VALVE OFFSET.
–PR129: LAST EGR VALVE OFFSET > or = PR128 if the valve is new.
Programming PR128 and PR129 must be cleared every time the exhaust gas recirculation valve is replaced.
PROCEDURE to be followed after replacing the exhaust gas recirculation valve:
- Run command SC036 Reinitialise programming.
- Select EGR valve as the operation type, then follow the instructions given by the diagnostic tool.
• When the command is finished,
–switch off the ignition,
– wait for the diagnostic tool message (maximum wait 8 minutes): Loss of dialogue with the computer: EDC16
CP33, check the tool connection and the computer supply.
The new EGR valve offset is automatically reprogrammed the next time the ignition is switched on.
– start the vehicle to enable the latest EGR valve offset to be programmed,
– switch off the ignition,
– wait for the diagnostic tool message (maximum wait 8 minutes): Loss of dialogue with the computer: EDC16
CP33, check the tool connection and the computer supply before switching the ignition back on.
The last EGR valve offset reprogrammed is stored on the computer.
– then check the system faults, and clear any stored faults,
– if there are faults, deal with the present faults,
– clear the faults from the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
End of the procedure.Note:
When reinitialisation is complete, the Emission control / EOBD sub-function displays: PR128 = PR129 = 0%
Note:
When the new EGR valve offset has been reprogrammed, the Emission control / EOBD sub-function will display:
10% < PR128 < 40%
PR129 = 0%
Note:
When the last EGR valve offset has been reprogrammed, the Emission control / EOBD sub-function will display:
10% < PR128 < 40%,
10% < PR129 < 40%

REPLACING THE INJECTORS
After one or more injectors have been replaced, enter the IMA codes again and then run command SC036
Reinitialise programming.
To do this, record the IMA code(s) etched on the injector bodies, and enter the codes into the computer using
command SC002 Enter injector codes, and follow the instructions given by the diagnostic tool. Run command
SC036 Reinitialise programming and select injectors, then follow the procedure. Note:
The "IMA" code (individual injector correction) is a calibration with corrective values unique to each injector,
and is used to adjust their flow accurately (injector classification). This correction takes into account mechanical
variances and the variances of the piezo actuator. An injector's class is determined by measurements taken at
different pressures on a test bench. The IMA class identification (7-character alphanumeric code) is then
engraved on the collar of the injector.
The IMA codes must be read from left to right:
– Foolproofing for reading the IMA codes is carried out using the low pressure return connector and/or the
electrical connector on the injector.
– This reading direction is valid when these connectors are located to the left of the cotech.
The IMA codes are read from left to right (see illustration in MR 402 (Vel Satis ph2), MR 395 (Laguna II ph2),
MR 364 (Mégane II ph2), MR 370 (Scénic II ph2), MR 405 (Espace IV ph2) Mechanical, 13B Diesel injection,
Diesel injector, Removal – Refitting)
Note: When entering characters, confusion can arise between:
– Figure 1 and the letters I and L,
– Figure 2 and the letter Z,
– Figure 5 and the letter S,
– Figure 6 and the letter G,
– Figure 8 and the letter B.
After programming or reprogramming the computer, it is essential to enter the 4 injector codes before confirming
the entry.
These individual corrective values are then written to the computer EEPROM, which can then control the injectors,
taking into account their manufacturing variation.
IMPORTANT:
Engines can only operate correctly if the correct IMA* codes have been entered. If no code has been
entered, or if an invalid code has been entered, fault DF066 Injector code(s) is present and the engine will
run in defect mode (engine speed limited significantly). If another injector's code has been entered, the
system will accept it but will make the wrong correction. This could lead to engine damage, loss of
performance and excessive pollution.
Always use the correct injector codes for the engine cylinder/computer.
Note:
On the M9R engine (Renault - Nissan partnership engine), cylinder no. 1 is located at the timing end.
