NOTESConditions for applying fault finding procedures to stored faults:
Apply this fault finding procedure if the fault reappears as present or stored after it has
been cleared and the ignition has been switched off and on again.
Special note:
Run command AC021 Display test. Three colours are displayed on the screen: Red,
green and blue, and a black mosaic on a white background. If this is not displayed,
apply the fault finding procedure detailed below.
Use the Wiring Diagram Technical Note for the vehicle concerned.
Check the condition and connection of the video connector on components 261 (Trafic: 662) and 1127 (bent
pins, bad contacts, etc.).
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:
●connection code 46M,
●connection code 46N,
●connection code 46BG,
●connection code 46BH,
●connection code 46BK,
between components 261 (Trafic: 662) and 1127.
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.
Check for + 12 V on connections 46M and 46N of the connector of component 1127.
Also check for earth on connections 46BG, 46BH and 46BK of the connector of component 1127.
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.
If the fault is still present, contact the Techline.
AFTER REPAIRCheck that the screen is operating correctly using command AC021 Display test.
Deal with any faults displayed by the diagnostic tool.
Clear the faults from the 4R radio navigation computer memory using command RZ001

NOTESConditions for applying fault finding procedures to stored faults:
Apply this fault finding procedure if the fault reappears as present or stored after it has
been cleared and the ignition has been switched off and on again.
Special note:
If the vehicle does not have a fold-out unit, check the 4R radio navigation computer
configuration (see Configuration and programming).
The screen does not deploy or there is no display on the instrument panel.
Apply the following fault finding procedure only if the vehicle is equipped with a fold-out
unit and a dot matrix display on the instrument panel (top of the range Mégane II
phase 2).
Use the Wiring Diagrams Technical Note for the Mégane II.
Check the condition and connection of the connectors of components 261, 1303 and 247 (bent pins, bad
contacts, etc.).
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.
Manipulate the wiring harness in order to produce a change in the fault status (present → stored).
Check the insulation, continuity and the absence of interference resistance on connection 34GG between
components 261 and 1303.
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.
Check the insulation, continuity and the absence of interference resistance on connection 34GD between
components 247 and 1303.

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.
