PR037REFRIGERANT PRESSURE
PA R A M E T E R
DEFINITIONThis parameter indicates the refrigerant pressure in bar.
NOTESSee the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant temperature >
80°C.
The refrigerant pressure must be between 2 bar < PR037 < 27 bar.
Check the cleanliness and condition of the refrigerant pressure sensor and its connections, component code
1202 and the injection computer connections, component code 120.
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.
Disconnect the battery and the injection computer.
Using the universal bornier in place of the computer, check for insulation and continuity on the following
connections:
–38Y between components 120 and 1202,
–38X between components 120 and 1202,
–38U between components 120 and 1202.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, replace the refrigerant pressure sensor, component code 1202 (see MR 388 (Logan and
Sandero), MR 451 (Duster), MR 423 (Thalia 2/Symbol 2), MR 430 (Clio II F 6) or MR 374 (Kangoo VLL),

ALP 1 No dialogue with the computer
NOTESSee the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
Try to establish dialogue with a computer on another vehicle to make sure that the diagnostic tool is not faulty. If
the tool is not the cause and communication cannot be established with any other computer on the same vehicle,
it is possible that another computer is disrupting the multiplex network.
Check the voltage of the battery.
If the battery voltage is between 9.5 V and 17.5 V, run fault finding on the charging circuit.
– Check the presence and condition of the injection fuses on the UPC and in the engine fuse box.
– Check the connection of the computer connectors, component code 120.
– Check the injection computer earths (quality, oxidation, tightness of the earth bolts on the battery terminal).
– Check that the supply to the computer is correct:
–Earth on connection NH of component 120 (for Logan, Sandero, Duster, Kangoo VLL),
–Earth on connection N of component 120 (for Thalia 2/Symbol 2),
–Earth on connection NF of component 120 (for Clio II F 6)
–+ 12V on connection 3FB of component 120.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check that the diagnostic socket, component code 225 is correctly supplied:
–+ before ignition feed on connection BP56 of component 225 (for Logan, Sandero, Duster),
–+ before ignition feed on connection BP10 of component 225 (for Thalia 2/Symbol 2, Clio II F 6, Kangoo
VLL),
–+ after ignition feed on connection AP10 of component 225,
– Earth on connections MAM and NC of component 225 (for Logan, Sandero, Duster
),
– Earth on connections N and M of component 225 (for Thalia 2/Symbol 2, Clio II F 6),
– Earth on connections NA and MK of component 225 (for Kangoo VLL).
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If dialogue has still not been established after these checks, contact the techline.
