BATTERY VOLTAGE
NOTESThere must be no present or stored faults.
Use the Wiring Diagram Technical Note for the vehicle concerned.
Check the permanent + feed fuse of component 261 (Trafic: 662).
Check the condition of the connectors of components 710 (Laguna), 260 (Mégane II and Scénic) or
1016 (commercial vehicle) according to the location of the fuse.
If the voltage is at minimum:
Check the battery and the charge circuit (see Technical Note 6014A Checking the charge circuit).
If the voltage is at maximum:
Check that the charging voltage is correct with and without electrical consumers switched on.
AFTER REPAIRRepeat the conformity check from the start.

Run fault finding on the ABS system (see 38C, Anti-lock braking system).
If there is no ABS system fault indicated, check connection 47F between components 1094 and 261 (Trafic: 662).
If the connection is 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, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.

EXTERNAL TEMPERATURE
NOTESOnly apply the checks if the parameter is inconsistent.
There must be no present or stored faults.
Special notes:
On the Laguna, Trafic, Master and Master propulsion, the exterior temperature
information is supplied by the exterior temperature sensor.
On Mégane and Scénic, this information comes from the UCH.
Use the Wiring Diagram Technical Note for the vehicle concerned.
Only for Laguna, Trafic, Master and Master propulsion
Check the condition and connection of the connector of component 240 (component 239 for right-hand drive
vehicles) and the black 24-track connector of component 261 (Trafic: 662).
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.
Using the universal bornier, check the insulation, continuity and the absence of interference resistance on
the following connections:
Left-hand drive:
●47C connection code,
●47D connection code,
between components 261 (Trafic: 662) and 240.
Right-hand drive:
●47C connection code,
●connection code 47D,
between components 261 (Trafic: 662) and 239.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
AFTER REPAIRRepeat the conformity check from the start.

NOTESThere must be no present or stored faults.
Use the Wiring Diagram Technical Note for the vehicle concerned.
Check the condition and connection of the GPS coaxial connector of the following components (bent pins, bad
contacts, etc.):
Commercial vehicle: 662 and 886.
Mégane cabriolet: 261, 1551 and 886.
Mégane and Scénic: 886 and 261.
Laguna: 261 and 1551.
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.
Disconnect the GPS coaxial cable at the rear of component 261 (Trafic: 662) and measure the resistance between
the core and the shielding.
If the resistance is less than 30 ΩΩ Ω Ω
, disconnect the GPS coaxial cable from the cut-off plate at the rear and check
the insulation, continuity and absence of interference resistance on the GPS coaxial cable at the rear of
component 261 (Trafic: 662).
If the connections are not correct, replace the coaxial cable.
If the connections are correct, replace the GPS aerial.
