REFRIGERANT PRESSURE
NOTESThere must be no present or stored faults.
Perform this fault finding procedure after an inconsistency is displayed in the
Parameters menu or after a customer complaint (no air conditioning, etc.).
Step 1
– Start the engine, switch on the air conditioning and increase the engine speed to 1,500 rpm:
– Display PR037 Refrigerant pressure in the Cold loop function on the diagnostic tool:
If the pressure is greater than ~27bar, go to step 2.
If the pressure does not rise, or remains below normal:
– Ensure that the air conditioning compressor and the relay are operating correctly.
– Check the conformity of the refrigerant pressure sensor by comparing* the value displayed by the tool (PR192)
with the reading given by the charging station high pressure gauge.
If the pressure difference = ±1.5bar, (or 1500 mbar):
Check the continuity and the absence of interference resistance on the connections between:
Injection computer, grey 24-track connector C,
track C3Track A of the refrigerant pressure sensor
Injection computer, brown 48-track connector
B, track F1Track C of the refrigerant pressure sensor
Injection computer, brown 48-track connector
B, track F3Track B of the refrigerant pressure sensor
If these connections are not faulty, replace the refrigerant pressure sensor.
If there is no difference, the refrigerant pressure sensor is correct: go to step 2.
Step 2
– Perform fault finding on the air conditioning.
*Note:
The diagnostic tool displays the absolute pressure, the charging station high pressure gauge displays the relative
pressure.
The normal difference between the two is equal to atmospheric pressure, i.e. ~1,000mbar.
AFTER REPAIRRepeat the conformity check from the start.

Fault finding - Interpretation of commands
SC001
WRITE SAVED DATA
NOTESAll data must be backed up with command SC003 Backup computer data for this
command to be run.
Writing is carried out after the computer has been reprogrammed or replaced.
Confirming this command writes the data backed up using command SC003 Backup computer data.
The data is as follows:
– Vehicle-specific idle speed.
– Options available on the vehicle and managed by the computer (Example: Air conditioning).
– Injector calibration codes (if the vehicle is fitted with IMA).
– Programming of exhaust gas recirculation valve data.
They will configure the computer and will enable it to avoid:
– engine malfunction after reprogramming or replacing the computer,
– faulty interpretation of information provided by the CLIP tool.
AFTER REPAIRRestart the conformity check from the beginning.

SAVE COMPUTER DATA
NOTESThe data is saved before computer reprogramming or the computer is replaced.
Selecting this command saves the following vehicle-specific data:
– Vehicle idle speed.
– Injector calibration codes (if the vehicle is fitted with IMA).
– Programming of exhaust gas recirculation valve data.
– Options available on the vehicle and managed by the computer (Example: Air conditioning).
This information will be saved in the CLIP tool.
●Before replacing or reprogramming the computer:
–Select SC003 SAVE COMPUTER DATA.
– if the following message appears: backup file exists, do you want to overwrite it?:
(this file corresponds to the last save carried out on the tool)
Select YES.
When the save has been performed, replace the computer or carry out the programming then proceed to the next
step.
Once the backup is complete, run the command SC001 Write backed up data to reconfigure the computer.
AFTER REPAIRRestart the conformity check from the beginning.

RZ005
PROGRAMMING
NOTESThis command is only executed after replacing the computer.
Command RZ005 reconfigures the computer.
If the computer does not have any configuration data, run command RZ005 to enter the vehicle options:
– air conditioning,
– passenger compartment heating resistors,
– cruise control.
These options are detected by the computer even if command RZ005 is not used.
The computer is configured as soon as the one of the vehicle's optional system components is operated.
AFTER REPAIRRestart the conformity check from the beginning.
