System outline
The high pressure injection system is designed to deliver a precise quantity of diesel fuel to the engine at a set
moment.
It is fitted with a BOSCH computer, type EDC16CP33.
The system comprises:
– a priming bulb,
– a diesel filter,
– a high pressure pump,
– a fuel pressure regulator (or actuator) on the high pressure pump (MPROP),
– a fuel pressure regulator (or actuator) mounted on the injector rail (DRV),
– an injector rail,
– a fuel pressure sensor,
– four piezoelectric injectors,
– a diesel temperature sensor,
– a coolant temperature sensor,
– an upstream air temperature sensor,
– a cylinder reference sensor,
– an engine speed sensor,
– a turbocharger pressure sensor,
– an exhaust gas recirculation valve,
– a recycled gas cooling solenoid valve,
– an accelerator pedal potentiometer,
– an atmospheric pressure sensor integrated into the injection computer,
– a flow sensor,
– a turbocharging limiter solenoid valve,
– a damper valve,
– a particle filter,
– a turbo upstream temperature sensor,
– a turbo upstream pressure sensor,
– a particle filter differential pressure sensor,
– a particle filter upstream temperature sensor,
– a particle filter downstream temperature sensor,
– an electric coolant pump (turbocharger),
– four thermoplungers.
The common rail direct high pressure injection system works sequentially (based on the petrol engine
multipoint injection).
This system uses piezoelectric injectors which enable a more precise injection since opening and closing times
are shorter compared to conventional solenoid injectors.
This injection system reduces operating noise, reduces the volume of pollutant gases and particles and produces
high engine torque at low engine speeds thanks to a pre-injection procedure.
The high pressure pump generates the high pressure and transmits it to the injector rail. The actuator located on
the pump controls the quantity of diesel supplied, according to the demand determined by the computer.
The rail supplies each injector through a steel pipe. The actuator located on the injector rail controls the pressure
of diesel fuel in the rail according to the demand determined by the computer.

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%
