Measure the resistance of component 240 (External temperature sensor) between the following connections:
●Connection code 47C,
●Connection code 47D.
Approximate temperature in ˚C Sensor resistance in Ω
between 0 and 5 between 5400 and 6200
between 11 and 15 between 3700 and 4400
between 21 and 25 between 2500 and 3000
between 31 and 35 between 1700 and 2100
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.
Replace the sensor if necessary.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.

NOTESSpecial note:
Attempt to apply forced + after ignition feed to update the faults.
Use Wiring Diagrams Technical Note for MEGANE II or SCENIC II.
CC.1
NOTESAttempt to apply forced + after ignition feed to update the
faults.
Check the condition and connection of the steering column lock connector.
If the connector is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
Check the condition and connection of connectors PE2, PP2 on the UCH and connectors PEH (UPC Vdiag 44)
or CT1 (UPC Vdiag 48) on the UPC (bent or broken tabs, etc.).
If the connector(s) is 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 and continuity of the following connections:
●Connection code 26I,
●Connection code 26AZ,
●Connection code 26BA, between the steering column lock (component code 1088) and the UCH
(component code 645)
●Connection code AP15, between the steering column lock (component code 1088) and the Protection and
Switching Unit (component code 1337)
If the connection(s) is faulty and if 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, contact the Techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.
