STOREDLEFT-HAND DIRECTION INDICATOR CIRCUIT
CO.0: Open circuit or short circuit to earth
1.DEF: Bulbs not working or open circuit
NOTESConditions for applying the fault finding procedure to a stored fault:
If the fault appears after action on the left-hand direction indicator control stalk, then
apply this fault finding procedure.
Special note:
The fault becomes stored after changing a bulb.
Use Wiring Diagrams Technical Note for MEGANE II or SCENIC II.
Check the bulbs.
Replace them, if necessary.
Check the condition and connection of the left-hand headlight connector, the left-hand repeater and the rear
left-hand light.
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 for earth on components 227 and 268.
If the connection 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 the wiring.
Check for earth on connection MZ of component 173.
If the connection 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 the wiring.
With the command running, check for + 12 V on connection 64C of components 227 and 268.
If the connection 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 the wiring.
Check the condition and connection of connector PP3 and connector PP2 on the UCH.
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 insulation and continuity of the following connection:
●Connection code 64C between components 645 and 173.
If the connection 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 the wiring.
If correct, check the connection between the UCH and front and rear lights (see wiring diagram), check the bulbs
again and if still not correct, replace the rear lights(s).
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.

NOTESAfter unlocking, opening a door causes timed supply, which is indicated by the starting
switch on the instrument panel lighting up.
Before any check on the UCH connections, unlock the vehicle.
Use Wiring Diagrams Technical Note for MEGANE II or SCENIC II.
Check the condition and connection of the connectors on the UCH and the connectors on the UPC.
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 for + 12 V on connection BPT of component 645.
If the connection is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check for earth on connection NAM of component 645.
If the connection is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
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.

IMPORTANT:
Wait 1 minute and 30 seconds before checking the change of status.
–If the original status is: over-inflated or under-inflated
Consult ALP 52 "Adjust tyre pressure" message appears (the wheel concerned is highlighted on the
display) and ALP 56 "Adjust tyre pressure" message appears (2 wheels are highlighted on the display).
–If the original status is: puncture
Consult ALP 56 "Stop! Tyre puncture" message appears (the wheel is highlighted on the display).
–If the original status is: absent
Consult ALP 54 "Tyre sensor fault" message appears (wheel warning light disappears) and ALP 55 "Tyre
sensor fault" message appears (4 wheel warning lights disappear).
If the status does not change, replace the sensor on the wheel concerned by following the instructions and the
programming procedure for the four valve codes, SC002 Program 4 valve codes (see Configurations and
programming).
AFTER REPAIRDeal with any other possible faults.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

ET047 Undetermined without depressing the pedal.
Check the condition and connection of the brake pedal switch 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 for + 12 V on connection BPT of component 160.
If not correct:
–Check the condition and connection UCH connectorPP3. 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.
–With the UCH and the brake pedal switch disconnected, check the insulation in relation to earth and the
continuity of the following connection:
●Connection code BPT between components 645 and 160.
If the connection 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 the wiring.
Remove the brake pedal switch and check the continuity between connections BPT and 5A of component 160
(switch piston pressed).
Only replace the brake pedal switch if it is not correct.
Check the condition and connection of the UCH connector PE2.
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.
With the UCH and brake light switch disconnected:
Check the insulation and continuity of the following connection:
●Connection code 5A, between components 645 and 160.
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.
The line is shared with the injection computer and the automatic transmission computer (if the vehicle is fitted with
an automatic transmission).
In the event of faulty insulation, it is therefore necessary, using a wiring diagram, to check the connections between
the brake pedal switch connector and these computers.
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.
