Special notes:
On the Laguna, Trafic, Master and Master propulsion, the exterior temperature
information is supplied by the exterior temperature sensor.

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:

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.

RADIO FIELD INTENSITY
NOTESThere must be no present or stored faults.
Engine stopped, ignition on.
Tune to a known FM or AM station with the vehicle in an open area if possible.
The "Radio field intensity" corresponds to the electrical intensity of the radio signal (FM or AM) received at the
radionavigation tuner input, at the frequency currently selected. It is expressed in dB µV.
It gives an indication of the radio reception level. Below 18 dB µV, the station is considered weak and does not
appear in the list of radio stations.
A low value (< 18 dB µV) on this parameter means that:
–Either the selected station has a weak transmission in the geographical area. This may be due to the
distance from the selected station's transmitter (far from urban area, on motorways) or obstacles interfering
with the transmission of radio waves (mountainous areas, buildings, deep valleys).
–Or, if the reception conditions are good in the geographical area for the selected station, there is a fault on
the vehicle's reception system: one of the components (aerial/aerial amplifier/coaxial connection/radio aerial
connector) is faulty. In this case, refer to ALP 4.
This parameter may be used to compare two vehicles in order to determine if there actually is a vehicle fault.
