Conditions for applying the fault finding procedure to a stored fault:
– The fault is declared present if the EOBD (European On Board Diagnostic)
warning light is lit.
Check the multiplex network.
Check the condition of the automatic transmission computer connector (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, Espace IV ph2, component code 119).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, Espace IV ph2, 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, otherwise replace the wiring.
Check the insulation to earth, the continuity and absence of interference resistance on the following
connections:
•3MT between components 119 and 120,
•3MS between components 119 and 120.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Repairing

To interpret the result, apply the interpretation of command SC035 (see Interpretation of commands).
With the engine stopped and ignition on, view parameters PR035 Atmospheric pressure and PR041
Turbocharging pressure.
If there is a difference of > 100 mbar, check that the atmospheric pressure reading is consistent (by comparison
with another vehicle for example).
If atmospheric pressure is consistent, replace the turbocharging sensor.
If not, contact the Techline.
Use the Monitool application: MT001 Turbocharging function to check the entire air line (only for Vdiag 04 and
