Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring may temporarily remove the cause of a fault.
Electrical measurements of voltage, resistance and insulation are generally correct, especially if the fault is not
present when the analysis is made (stored fault).
Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the fuses, insulators and wiring harness routing.
Look for signs of oxidation.
Physical inspection
While manipulating the wiring, use the diagnostic tool to note any change in fault status from stored to present.
Make sure that the connectors are properly locked.
Apply light pressure to the connectors.
Twist the wiring harness.
If there is a change in status, try to locate the source of the fault.
Inspection of each component
Disconnect the connectors and check the appearance of the clips and tabs, as well as the crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the sockets.
Check that no clips or tabs have been dislodged during connection.
Check the clip contact pressure using an appropriate model of tab.
Resistance check
Check the continuity of entire lines, then section by section.
Look for a short circuit to earth, to + 12 V or to another wire.
If a fault is detected, repair or replace the wiring harness.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault becomes present with the engine running and an air conditioning request.
Order of priority in the event of more than one fault:
Deal with fault DF049 Refrigerant sensor circuit first if it is present or stored.
Use the CLIO III, MODUS, MEGANE II ph2 and SCENIC II ph2 Wiring Diagrams
Technical Note.
When the fault is present or stored, the heating and air conditioning system is inhibited. There is no longer any air
conditioning.
Check the air conditioning fuse and check the air conditioning compressor connector, component code 171.
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the continuity and insulation of the following connections:
– 38R between components 171 and 1337,

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.
Manually check if the compressor is jammed (turn the clutch plate manually to check that there is no point of
resistance).
In the event of jamming, replace the air conditioning compressor (see MR 364 (Mégane II), MR 370 (Scénic II),
MR 385 (Modus), MR 392 (Clio III), Mechanical, 62A, Air conditioning, Compressor:

NOTESOnly address this customer complaint after a complete check with the diagnostic
tool.
Try to establish dialogue with a computer on another vehicle to check that the diagnostic tool is not faulty. If the
tool is not at fault, and dialogue cannot be established with any other computer on the same vehicle, the cause
could be a faulty computer interfering on the multiplex network.
Check the voltage of the battery.
If the battery voltage is not between:
9.5 V < Battery voltage < 17.5 V
Carry out fault finding on the charge circuit (See Technical Note 6014A, Checking the charging circuit or 87G,
Engine compartment connection unit).
Carry out a fault finding procedure on the multiplex network using the diagnostic tool.
– 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 and the condition of its connections.
– Check the injection computer earths (quality, oxidation, tightness of earth bolts on the battery terminal).
– Check that the supply to the computer is correct:
Earth on code connection N* 2 of the computer connector.
+After ignition feed on connection code AP of the computer connector.
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 power supply to the diagnostic socket is correct:
+ before ignition feed on track 16
+ after ignition feed on track 1
Earth on tracks 4 and 5
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 Techline.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
