–Check the condition of the fuel pump relay connector (component code 236).
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Use the "universal bornier" to check the insulation and continuity of the following connection:
●3N between components 236 and 108,
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.
Carry out a fault finding procedure on the engine fuse and relay box to check the continuity of the following
connection:
●BP17 between components 120 and 597,
●BP17 between components 238 and 597.
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 it.
If the fault is still present, check the battery and run fault finding on the charging circuit (see Technical Note 6014A,
Checking the charging circuit).
–Clean the battery terminals and all connections to + and to Earth.
–Check the battery voltage.
–Check the charging circuit.
AFTER REPAIRFollow the instructions to confirm repair:
–If the fault is present, continue to deal with the fault.
–If the fault is stored, ignore it.
Deal with any other faults.
Clear the stored faults.

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.
Reconnect the Protection and Switching Unit connector and reconnect the battery.
With the ignition on, if there is no + 12 V on the connector of the quadruple ignition coil module, there is a fault in
the Protection and Switching Unit (see 87G, Engine Compartment Connection Unit).
If the fault is still present, replace the ignition quadruple coil module.

NOTESPriorities when dealing with a number of faults:
Deal with any other fault first.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after the engine starts.
Special notes:
The OBD warning light is lit.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,

Check the appearance and condition of the catalytic converter. Check there are no air leaks, thermal shock,
misfiring, coolant or oil consumption.
Run command SC006 Running OBD Test: catalytic converter. Before carrying out this test, repair all the
electrical faults and clear the fault memory. Check that fault DF436 Misfiring detection is not present and program
the engine flywheel target ET089 Flywheel target programming.
Carry out this test when the engine is warm, which reduces the time it takes for the catalytic converter to heat up.
At the end of this test, four different results are possible:
–Status 1: Fault finding not carried out/impossible to obtain the necessary conditions.
–Status 2: Component in an average condition.
–Status 3: Component in good condition.
–Status 4: Component in poor condition.
When fault finding is completed and the result read, stop the engine and start it again to establish normal operating
conditions.
If the result is status 1: check that there are no faults, and check the engine flywheel target programming using
ET089 Programming engine flywheel target.
If the result is status 2 or 4: replace the catalytic converter.
If the result is status 3: the catalytic converter is in good condition.
If the fault is still present, contact the Techline.

Clear the stored faults. Do not clear the programming.
To check that the system has been properly repaired:

system causing the EOBD pollutant emission thresholds to be exceeded.
The on-board diagnostic can detect:
–clogging of the injectors or an injector flow fault,
–a fault in the supply system (pressure regulator, fuel pump, filter, etc.),
–a poor connection in the petrol or injection circuits.
2.DEF: EOBD
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present with the engine running (wait for approximately
2 minutes).
Check:
–the fuel pressure,
–the fuel filter,
–the fuel pipes,
–clogging of the injectors or an injector flow fault (see MR 392 (Clio III), MR 385 (Modus), MR 411
(New Twingo), or MR 442 (E33), Mechanical, 13A, Fuel supply).
