Disconnect the GPS coaxial cable at the rear of component 261 (Trafic: 662) and measure the resistance between
the core and the shielding.
Is the value less than 30 ΩΩ Ω Ω
?
Yes No
Disconnect the GPS coaxial cable from the cut-off
plate at the rear and check the insulation,
continuity and the absence of interference
resistance on the GPS coaxial cable at the rear of
component 261 (Trafic: 662).
Is the check result correct?
No Yes
Replace the passenger
compartment GPS coaxial
cable.
Check the feed voltage on component 1551
(commercial vehicle, Mégane and Scénic: 886) (4.5 V
± 0.5 V) at the output of component 261 (Trafic: 662).
Is the check result correct?
Yes No
Replace component 1551.
Contact the Techline.
AFTER REPAIRCarry out a complete check with the diagnostic tool.

ALP 4 Poor radio reception
NOTESOnly check the customer complaint after performing a full check with the diagnostic
tool.
Use the Wiring Diagram Technical Note for the vehicle concerned.
Is the radio field intensity appropriate (see Interpretation of parameter PR010 Radio field
intensity)?Yes
No
Check the condition and connection of the connectors of component 261 (Trafic: 662) and
component 886.
Using the universal bornier, check the insulation, continuity and the absence of
interference resistance on the following connections:
●TB13 connection code.
●34AN connection code.
Between components 261 (commercial vehicle: 662) and 886.
Also check the feed to component 886 on connection 34AM (12 V ±± ± ±
1 V).
Are the connections faulty?
Yes No
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.
Has the fault been solved?
Yes No
End of fault finding.

Disconnect then reconnect component 1272.
Does the CD changer request its code?
("CD 0000")
No
Check the condition and connection of the connector of components 261 (Trafic: 662) and 1272.
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.
Has the fault been solved?
No
With the radio switched on, check for + battery feed
on connection 34BC and + accessories feed on
connection 34BD of the connector of
component 1272.
Are the + battery and + accessories feeds
present?
Yes
Contact the Techline.
YesRefer to ALP 10 The screen displays
"CD0000".
NoCheck the continuity, insulation and
the absence of interference resistance
on connections 34BC, 34BL and 34BD
between components 261 (Trafic: 662)
and 1272.
Yes Are the connections correct?
